Spitze 15 Gear Motor Manufacturers and Suppliers in China
Schnelle Antwort
China hosts over 3,000 gear motor manufacturers, with the top 15 suppliers controlling approximately 45% of export volume. The leading manufacturers—Greensky-Macht, Kinmore Motor, Ningbo Leison Motor, and Xiamen Dazhen Motor—distinguish themselves through IEC 60034-compliant efficiency ratings (IE2–IE4), ISO 9001 Qualitätssysteme, and full OEM/ODM customization capabilities. When sourcing gear motors from China, prioritize suppliers with verifiable CE/RoHS certifications, documented torque-density specifications, and minimum order quantities (MOQ) that align with your production schedule. Chinese gear motors typically cost 30–50% less than European equivalents while meeting the same NEMA MG 1 und IEC 60034 performance benchmarks, making them the preferred choice for global B2B buyers in robotics, industrielle Automatisierung, und Elektrofahrzeuganwendungen.
Was ist ein Getriebemotor??
A gear motor is an integrated electromechanical device that combines an electric motor (Wechselstrom oder Gleichstrom) with a gearbox (also called a gear reducer) in a single compact unit. The gearbox reduces the motor’s rotational speed while proportionally increasing its output torque, allowing the assembly to deliver high torque at low RPM—exactly what most industrial applications require. Entsprechend the International Energy Agency’s “Walking the Torque” report, electric motor-driven systems account for over 53% des weltweiten Stromverbrauchs, and gear motors represent a significant and growing segment of that total.
Key components of a gear motor include:
- Elektromotor — Provides the primary rotational power (AC-Induktion, Gleichstrom gebürstet, or brushless DC)
- Gear train — Reduces speed and multiplies torque through spur, spiralförmig, bevel, Wurm, or planetary gear configurations
- Gehäuse — Cast iron or aluminum enclosure providing structural integrity and heat dissipation
- Lager — Support the output shaft; SKF bearing life calculations are the industry standard for predicting service life
- Lubrication system — Grease-filled (sealed for life) or oil-bath lubrication for continuous-duty applications
How Gear Motors Work: Schritt-für-Schritt-Prinzip
Understanding the operating principle of a gear motor helps B2B buyers evaluate supplier specifications more critically. Here is the step-by-step power transmission chain:
Schritt 1: Electrical Input
AC power (single-phase 110/220V or three-phase 380/440V) or DC power (12V/24V/48V) is supplied to the motor’s stator windings. The input current creates a magnetic field that interacts with the rotor to generate rotational motion.
Schritt 2: Motor Shaft Rotation
The electromagnetic interaction produces torque at the motor shaft, typically at high speed (1,400–3,500 RPM for AC motors; 3,000–10,000 RPM for DC motors). This speed is far too high for most industrial applications, which is where the gearbox becomes essential.
Schritt 3: Gear Reduction
The motor shaft drives the input gear of the gearbox. Through a series of gear meshes (one or more stages), the rotational speed is reduced by the Übersetzungsverhältnis (ich). Zum Beispiel, a 3-stage helical gearbox with a ratio of 100:1 reduziert 1,400 RPM input to 14 RPM-Ausgabe.
Schritt 4: Drehmomentvervielfachung
As speed decreases, torque increases proportionally. The fundamental relationship is:
T_output = (T_motor × i × η_gearbox)
Where T is torque (N·m), i is the gear ratio, and η is the gearbox efficiency (typically 90–97% per stage). A motor producing 2 N·m of torque with a 100:1 ratio and 90% gearbox efficiency yields 180 N·m at the output shaft.
Schritt 5: Load Delivery
The output shaft delivers the reduced-speed, high-torque rotational power to the application—whether that is a conveyor belt, a lifting mechanism, a packaging machine, or a robotic joint. Der UNS. DOE’s Energy Conservation Standards require that gear motors sold in the U.S. meet specific efficiency benchmarks, with IE4 becoming mandatory for mid-range motors starting June 1, 2027.
Gear Motor Types: Funktionsvergleichstabelle
Before evaluating specific manufacturers, it is important to understand the four primary gear motor architectures available from Chinese suppliers. Each type has distinct efficiency characteristics, Drehmomentdichte, and application fit.
| Besonderheit | Stirnradgetriebemotor | Stirnradgetriebemotor | Schneckengetriebemotor | Planetengetriebemotor |
|---|---|---|---|---|
| Gear Efficiency | 90–95 % | 94–98% per stage | 50–90 % (ratio-dependent) | 95–97% per stage |
| Drehmomentdichte | Niedrig–Mittel | Mittel–Hoch | Medium | Hoch (kompakt) |
| Geräuschpegel | Mäßig | Niedrig (smooth mesh) | Low–Moderate | Sehr niedrig |
| Gegenreaktion | 5–15 arcmin | 3–10 arcmin | Self-locking (no backlash) | 1–6 arcmin |
| Maximales Verhältnis (einstufig) | 5:1–8:1 | 5:1–10:1 | 5:1–80:1 | 3:1–10:1 |
| Cost Range | $ | $$ | $$ | $$$ |
| Typische Anwendungen | Förderer, simple drives | Industrielle Automatisierung, Pumps | Lifting, Tore, Lebensmittelmaschinen | Robotik, precision positioning, AGVs |
| Self-Locking | Nein | Nein | Ja (ratio ≥ 30:1) | Nein |

Technische Daten: Efficiency Standards, Temperaturgrenzen, and Torque Formulas
When comparing Chinese gear motor suppliers, three engineering parameters matter most: Effizienzklasse, thermische Grenzen, und Drehmomentabgabe. These are governed by international standards that all reputable manufacturers must comply with.
IEC 60034-30-1 Effizienzklassen
Die IEC 60034-30-1 standard defines four (soon five) efficiency classes for electric motors. Der UNS. DAMHIRSCHKUH 2027 rule will require IE4 for mid-range motors (100–250 hp), aligning U.S. standards with the EU’s existing IE4 mandate.
| IE-Klasse | Designation | Example Efficiency (4-Pole, 1.5 kW, 50 Hertz) | Regulierungsstatus |
|---|---|---|---|
| IE1 | Standardeffizienz | 77.2% | Phased out in EU and China for most ratings |
| IE2 | Hohe Effizienz | 82.8% | Minimum in many developing markets |
| IE3 | Premium-Effizienz | 85.3% | Current U.S. baseline (KEINE Prämie); EU-Minimum seitdem 2021 |
| IE4 | Super-Premium-Effizienz | 88.2% | UNS. DOE obligatorisch im Juni 2027 for 100–250 hp; EU mandatory for 75kW+ |
| IE5 | Ultra-Premium-Effizienz | ~91% (target) | Not yet mandated; under development by IEC |
Quelle: IEC 60034-30-1:2014 efficiency values; KEIN MG 1 Teil 12 alignment confirmed by the NEMA-IEC harmonization agreement.
IEC 60034-1 Temperaturgrenzen der Isolationsklasse
The thermal performance of a gear motor’s windings directly affects its service life. Pro IEC 60034-1, insulation classes define the maximum allowable temperature rise above ambient (40° C):
| Isolationsklasse | Maximale Temperatur (° C) | Temperaturanstiegsgrenze (K) | Typische Anwendung |
|---|---|---|---|
| Klasse A | 105° C | 60 K | Veraltet; legacy equipment only |
| Klasse E | 120° C | 75 K | Small appliances, low-duty motors |
| Klasse b | 130° C | 80 K | Standard-Industriemotoren |
| Klasse F | 155° C | 105 K | Most common; gear motors for continuous duty |
| Klasse H | 180° C | 125 K | High-temperature environments, heavy-duty gear motors |
Reputable Chinese manufacturers such as Greensky Power specify Class F insulation as standard, with Class H available for high-ambient-temperature applications like steel mills and mining equipment.
Essential Torque and Efficiency Formulas
For B2B buyers evaluating gear motor specifications, these formulas are essential for verifying supplier claims:
1. Output Torque from Gear Ratio:
T_output = (9550 × P_motor × η_gearbox) / n_Ausgabe
Wo: T_output = output torque (N·m), P_motor = motor power (kW), η_gearbox = gearbox efficiency (decimal), n_output = output speed (U/min)
2. Gear Ratio Calculation:
i = n_Motor / n_Ausgabe
3. Overall System Efficiency:
η_total = η_motor × η_gearbox × η_coupling
For a typical IE3 motor (h = 0.853) with a 2-stage helical gearbox (η = 0.96² = 0.922) and coupling (h = 0.99): η_total = 0.853 × 0.922 × 0.99 = 0.779 (77.9%)
4. SKF Bearing Life (L10h):
L10h = (10⁶ / 60N) × (C/P)^p × a_SKF
Wo: C = basic dynamic load rating (kN), P = äquivalente dynamische Belastung (kN), p = 3 für Kugellager bzw 10/3 für Wälzlager, a_SKF = life adjustment factor per SKF rating life methodology
5. Servicefaktor (SF) für NEMA MG 1:
SF = Nennlast / Actual Load
NEMA motors typically carry SF = 1.15, bedeutet a 1 kW motor can safely handle 1.15 kW continuously. IEC motors use SF = 1.0, so buyers must size IEC motors to the actual load without derating margin.

Step-by-Step Gear Motor Supplier Selection Guide
Follow this structured process to select the right Chinese gear motor manufacturer for your application:
Schritt 1: Define Technical Requirements
Document your required output torque (N·m), Ausgangsgeschwindigkeit (U/min), Nennleistung (W or kW), Stromspannung (v), Arbeitszyklus (S1–S10 per IEC 60034-1), und Umweltbedingungen (Temperatur, Feuchtigkeit, IP-Schutzart). Calculate the required gear ratio using i = n_Motor / n_Ausgabe and verify that the output torque meets your application’s peak load with a 1.5× safety factor.
Schritt 2: Shortlist 3–5 Suppliers
From the list above, select manufacturers whose product categories match your requirements. Prioritize those with relevant certifications (CE for Europe, UL for North America, ISO/TS 16949 für Automobil) and demonstrated export experience to your target market.
Schritt 3: Request Technical Datasheets
Ask each supplier for complete datasheets including: Nennmoment, Nenngeschwindigkeit, gear ratio options, Effizienzklasse (IE1–IE4), insulation class, IP-Schutzart, Geräuschpegel (dB), Gewicht, and dimensional drawings. Cross-check torque claims using the formula T_output = (9550 × P × η) / N.
4: Evaluate Sample Quality
Order 3–5 samples for testing. Measure actual torque output using a dynamometer, verify noise levels in a soundproof chamber, and run a 500-hour continuous-duty test to validate thermal performance. Check that measured efficiency falls within the IEC 60034-2-1 tolerance band (±15% of (1-Die) for motors ≤150 kW).
Schritt 5: Audit Manufacturing Quality
If your annual volume exceeds 10,000 Einheiten, conduct a factory audit (either in-person or via third-party inspection). Verify ISO 9001 Dokumentation, check incoming material inspection records, review final test procedures (100% testing is standard at top-tier suppliers like Greensky Power), and inspect calibration records for test equipment.
Schritt 6: Negotiate Commercial Terms
Standard MOQ for Chinese gear motor manufacturers ranges from 100–1,000 units, but most suppliers offer sample orders (1–10 units) at a premium. Negotiate payment terms (30% Hinterlegung, 70% before shipment is standard), lead time (typically 25–35 days for standard products, 45–60 days for custom designs), and warranty terms (1 year minimum is industry standard; 2–3 years for premium suppliers).
Common Sourcing and Engineering Mistakes
B2B buyers frequently make these avoidable errors when sourcing gear motors from China:
| Fehler | Auswirkungen | Correct Approach |
|---|---|---|
| Selecting motor by rated power only, ignoring torque-speed curve | Motor cannot deliver required torque at operating speed | Always request the full torque-speed curve and verify torque at your application’s operating RPM |
| Overlooking service factor differences (ES GIBT KEIN 1.15 vs IEC 1.0) | IEC motor overheats under continuous peak load | Size IEC motors to actual load without derating; add 15% margin if switching from NEMA spec |
| Ignoring gearbox efficiency losses in total system efficiency | System efficiency 15–25% lower than expected | Calculate η_total = η_motor × η_gearbox; account for 3–10% loss per gear stage |
| Choosing worm gears for high-duty-cycle applications | Übermäßige Wärmeentwicklung, premature wear, efficiency as low as 50% | Use helical or planetary gears for continuous duty; reserve worm gears for intermittent or self-locking applications |
| Not specifying insulation class for high-ambient environments | Winding insulation failure at ambient >40° C | Specify Class H (180° C) for ambient temperatures above 50°C; derate motor by 1% per 100m above 1,000m altitude |
| Skip sample testing for large orders | Mass-production defects discovered after full shipment | Always test 3–5 samples with dynamometer and thermal testing before placing volume orders |
Gear Motor Troubleshooting Guide
| Problem | Wahrscheinliche Ursache | Lösung |
|---|---|---|
| Excessive noise and vibration | Worn gear teeth, misaligned coupling, or bearing failure | Inspect gear mesh for wear patterns; check shaft alignment with dial indicator; replace bearings per SKF L10h calculation |
| Output torque lower than rated | Insufficient motor power, gearbox efficiency degradation, or incorrect gear ratio | Verify motor voltage and current; measure actual gearbox efficiency; recalculate gear ratio using i = n_motor / n_Ausgabe |
| Motorüberhitzung (thermal trip) | Überlast, inadequate ventilation, or wrong insulation class for ambient | Measure actual load current vs. Typenschild; verify ambient temperature ≤40°C; upgrade to Class H insulation if needed |
| Gearbox oil leakage | Worn seals, overfilling, or breather vent blockage | Replace shaft seals; fill oil to specified level (sight glass); clean or replace breather vent |
| Output shaft won’t turn (motor runs) | Gear tooth breakage, seized bearing, or foreign object in gear train | Disassemble gearbox; inspect for broken teeth and bearing condition; flush and relubricate |
| Motor starts but gearbox output is erratic | Keyway wear, loose coupling, or intermittent gear engagement | Inspect key and keyway for wear; tighten coupling bolts; check for gear tooth damage |
| Excessive current draw at startup | High starting torque requirement or insufficient gear ratio reduction | Use a motor with higher starting torque (NEMA Design C) or increase gear ratio; consider VFD soft-start |
| Premature bearing failure | Inadequate lubrication, contamination, or overloaded bearing | Follow relubrication intervals per manufacturer; verify bearing load using SKF L10h formula; upgrade to sealed bearings if contamination is present |
FAQ
What is the difference between a gear motor and a regular motor?
A regular electric motor produces high rotational speed (1,400–3,500 RPM for AC, 3,000–10,000 RPM for DC) with relatively low torque. A gear motor integrates a gearbox that reduces the output speed while proportionally increasing torque. Zum Beispiel, a 1.5 kW motor at 1,400 RPM erzeugt ungefähr 10.2 N·m of torque; mit einem 50:1 Getriebe (95% Effizienz), the gear motor outputs 28 Drehzahl bei 485 N·m—nearly 48× the torque at 1/50th the speed.
Which Chinese gear motor manufacturer offers the best customization?
For full OEM/ODM customization, Greensky Power and Nanjing FASTECH stand out. Greensky offers integrated motor + Regler + sensor solutions with 8 PhD-level engineers and 10% revenue reinvestment in R&D. FASTECH provides one-stop service from mold development to mass production and serves as OEM for Western brands including Regal Beloit Group’s MARATHON line.
What certifications should I look for when importing gear motors from China?
At minimum, require ISO 9001 (Qualitätsmanagement), CE (European market access), and RoHS (hazardous substance compliance). For North America, look for UL certification. For automotive applications, ISO/TS 16949 is mandatory. For environmentally regulated markets, ISO 14001 is a plus. For explosion-proof applications (Bergbau, chemisch), ATEX or IECEx certification is required. All reputable manufacturers should also comply with IEC 60034 efficiency standards and NEMA MG 1 if exporting to the United States.
How much does a gear motor cost from Chinese suppliers?
Pricing varies widely by type and power rating. Small DC spur gear motors (6–12mm) start at $2.80–$4.80 per unit (MOQ 100). Mid-range AC gear motors (25W–370W) range from $20–$100. Industrial planetary gear motors (500W–3kW) cost $150–$800. Large industrial gearboxes (10kW+) can exceed $2,000. Chinese gear motors typically cost 30–50% less than European equivalents (Sew-Eurodrive, Siemens, Nord) while meeting the same IEC efficiency standards.
What is the typical lead time for gear motors from China?
Standard (catalog) gear motors typically ship in 25–35 days. Custom-designed gear motors with modified shafts, mounting flanges, or gear ratios require 45–60 days. Suppliers in Guangdong and Zhejiang industrial clusters can often expedite urgent orders within 72 hours for an additional fee. Always confirm lead times in writing and build a 15% buffer into your production schedule.
Are Chinese gear motors as reliable as European or American brands?
When sourced from reputable manufacturers with proper certifications (ISO 9001, CE, UL), Chinese gear motors achieve comparable reliability to Western brands. The key is to verify compliance with IEC 60034 und NEMA MG 1 Standards, request 100% individuelle Prüfung (standard at top-tier suppliers like Greensky Power and Kinmore Motor), and conduct sample testing before volume orders. Der IEA reports that motor system efficiency improvements of 10–15% are achievable globally, and Chinese manufacturers are increasingly producing IE4-class motors that match or exceed Western efficiency benchmarks.
Warum sollten Sie sich für Greensky Power entscheiden??
Among the 15 manufacturers profiled above, Greensky Power occupies a unique position in the Chinese gear motor market. Here is what differentiates Greensky from other suppliers:
1. Vertically Integrated Manufacturing: Greensky operates four specialized subsidiaries covering stepper motors and BLDC controllers (Jinhua Greensky), micro AC motors and gearboxes (Shaoxing Fuhua Pump), Drehmomentsensoren (Sky Magnetic Tech), and North American service (United Motion Inc.). This vertical integration means buyers can source complete motion systems—including motors, Getriebe, Controller, and sensors—from a single supplier, reducing integration risk and lead time.
2. Engineering-Driven Culture: Mit 8 PhD-level engineers and 10% of annual revenue reinvested in R&D, Greensky approaches motor manufacturing from an engineering-first perspective rather than a pure cost-optimization model. Their advanced testing facilities include high-low temperature chambers, Koordinatenmessgeräte (CMM), stille Räume, and dynamometers—equipment that many competing Chinese manufacturers lack.
3. 100% Individual Product Testing: Unlike manufacturers that perform batch sampling, Greensky tests every single motor before shipment. Das 100% inspection rate ensures consistent quality and dramatically reduces the risk of receiving defective units in volume orders.
4. International Standards Compliance: All Greensky products are manufactured in compliance with IEC 60034 efficiency standards, CE certification, und ISO 9001:2015 Qualitätsmanagement. Ihre AC and DC motors meet NEMA MG 1 performance benchmarks, and their stainless steel gearboxes are designed for food-grade and pharmaceutical washdown environments.
5. Global Trade Show Presence and Local Support: Greensky has exhibited at the Vietnam Industrial Expo, Germany SPS IPC Drives (2017, 2018, 2019), and Thailand Manufacturing Expo. For North American customers, United Motion Inc. provides local technical response, Unterstützung bei der Probenprüfung, Lieferkoordination, and after-sales warranty support—eliminating the communication and timezone barriers that plague many China sourcing relationships.
6. Produktionsmaßstab: Mit 1.5 million gear motors and 4 million controllers produced annually, Greensky has the capacity to serve both low-volume custom projects and high-volume OEM contracts. Their product range spans AC right-angle gear motors, 24V DC brushless gear motors, motor variators, Kegelradgetriebe, und single-phase motors—covering applications from industrial automation to high-torque lifting systems.
