1.5 kW BLDC Motor
1500 W of continuous brushless power for electric vehicles, AGV, industrial automation and pumps. Compared with a 1000 W motor, the jump is not only power: current, heat and controller sizing all change, and they decide whether the drive survives a full shift.
What 1.5 kW Actually Changes
Going from 1000 W to 1500 W is not a 50% bigger motor in the same envelope. At 48 V a 1.5 kW drive pulls around 31 A continuously — before any acceleration margin — so cables, controller and battery all have to be sized again.
The second change is thermal. At >90% efficiency the motor still has to shed roughly 150 W as heat, which is why the cooling method and the IP rating are chosen together rather than separately.
- Higher continuous current — plan the wiring and controller for the peak, not the average
- Heat has to leave the motor — air cooling or a sealed IP65 build are different designs
- Torque and speed are a trade — you cannot have 10 N·m and 6000 rpm from 1.5 kW at once
What we build in this class
- 1500 W continuous, 48 V / 60 V / 72 V windings
- 3000 – 6000 rpm, with FOC controller matched to the winding
- Air cooled or sealed IP65, depending on the environment
- Planetary or helical gearbox for low-speed high-torque duty
1.5 kW BLDC Motor Options
Standard 1500W Motor
Stable performance and reliable output for general industrial use.
The default choice when the duty is known and steady.
High Torque Motor
Enhanced winding design with heavy load capacity for industrial machines.
Lower base speed, more torque per amp at the shaft.
Geared BLDC Motor
Low speed high torque with precision control for automation systems.
Planetary or helical reduction at the output flange.
High Speed Motor
High RPM output for performance applications and EV systems.
Up to 6000 rpm, with rotor balance and bearing choice to match.
Torque and Speed at 1.5 kW
Power, torque and speed are locked together by T = 9550 × P / n. The datasheet range of 5 – 10 N·m and 3000 – 6000 rpm describes the two ends of that curve, not one operating point.
| Speed | Torque at 1.5 kW |
|---|---|
| 1500 rpm (base speed) | 9.5 N·m |
| 3000 rpm | 4.8 N·m |
| 6000 rpm | 2.4 N·m |
The three marked points come straight from T = 9550 × 1.5 / n. If your duty needs 10 N·m at the shaft, that lands near 1430 rpm — either a lower base speed winding or a reduction stage.
Why Choose Our 1.5 kW BLDC Motors
Higher Power Output
More usable torque than a 1000 W motor in the same class of machine.
Torque for Heavy Duty
Winding and magnet choice aimed at continuous load, not just start-up peaks.
High Efficiency
Above 90%, so less heat to remove and longer battery runtime.
Flexible Customization
Voltage, speed, shaft, mounting and gearbox matched to your machine.

Continuous current at 1.5 kW: about 31 A at 48 V, 25 A at 60 V, 21 A at 72 V. Size the controller and cable for the acceleration peak above these figures. A 1.5 kW build is configured winding-by-winding; the drawing set is issued against your duty, not taken from a catalogue page.
Send the voltage, the torque or speed your machine needs, and the duty cycle. We return the 1.5 kW winding, controller pairing and a drawing set — usually within 24 hours.

- Duty point — the torque and speed the machine runs at, and how long it holds them.
- Bus voltage — 48 V, 60 V or 72 V, and the battery or rectifier behind it.
- Environment — indoor, dusty or washdown, which settles air cooling versus IP65.
- Mounting — flange, shaft and whether a gearbox goes on the output.

FAQ – 1.5 kW BLDC Motor
What is the advantage of 1.5 kW over a 1000 W motor?
Higher torque and power output for heavy-duty and industrial duty, with headroom for acceleration. The trade is current and heat: at 48 V a 1.5 kW drive draws about 31 A continuously, so the controller and cabling are sized for more than the motor alone.
What voltage options are available?
48 V, 60 V and 72 V, depending on your application. The higher the bus voltage, the lower the current for the same 1.5 kW — about 31 A at 48 V against 21 A at 72 V — which makes wiring and controller choice easier.
Can torque and speed both be at the top of the range?
No. Power is the product of torque and speed: 1.5 kW gives about 9.5 N·m at 1500 rpm, 4.8 N·m at 3000 rpm and 2.4 N·m at 6000 rpm. If your machine needs 10 N·m and high speed at the same time, that is a bigger motor or a reduction stage, not a different winding.
Do you support OEM customization?
Yes — voltage and speed, controller and system integration, gearbox matching, thermal and efficiency optimisation, custom shaft and mounting, from prototype through small batch to volume production.
IP54 or IP65 — which should I take?
IP54 suits indoor machinery where dust and splash are occasional. IP65 is for washdown, outdoor and dusty environments, but a sealed housing holds heat in, so the cooling design has to change with it. Tell us the environment and we specify both together.
