Speed Gate Gearmotor: Ratio, Backlash, Fail-Safe
A 100:1 planetary in a speed gate gearmotor multiplies motor torque by roughly 88 and divides motor speed by 100, so a 0.10 N·m, 3,080 rpm motor becomes a 9.3…

9S10P vs 12S8P: Choosing a Robotic Mower Blade Motor
At equal copper and magnet mass, a 9-slot 10-pole (9S10P) stator makes about 9% more torque per ampere than a 12-slot 8-pole (12S8P) one. We chose 12S8P for a…

BLDC Motor for Barrier Gate: Sizing, Torque & Duty-Cycle Guide
For boom barrier gates, choose a 24V DC BLDC motor. Use 36V/48V only if the boom exceeds 5 m or open time must stay under 1 s. Calculate torque by adding…
Read moreBLDC Motor for Stairlift | 24V Quiet-Drive Specifications
A BLDC motor for stairlift use is a 24 V brushless DC motor coupled to a self-locking worm or compound-stage gearbox, dimensioned for cabin speeds of 0.10 to…

Micro Pump Motor Manufacturer: What OEM Buyers Should Consider
Choosing a micro pump motor manufacturer is an engineering decision, not a purchasing one: the motor and its driver — not the pump head — set the ceiling on…

How to Select a Pump Motor for High-Viscosity Fluids: Torque, Speed and Material Compatibility
Viscosity is a fluid’s resistance to flow, measured in centipoise (cP) or millipascal-seconds (mPa·s, numerically equal to cP). Water is ~1 cP; heavy oils…

Magnetic Drive Pump vs Mechanical Seal Pump: Sealless vs Sealed for OEM Fluid Systems
A magnetic drive (sealless) pump transmits torque across a static containment shell by magnetic coupling — it has no shaft seal, so leakage is zero by design .…

Custom BLDC Motors for Micro Pump Applications
A custom BLDC pump motor is a brushless DC (or PMSM) drive motor whose winding, voltage, feedback and thermal design are tuned to a specific micro-pump duty…

How Fluid Viscosity Affects Gear Pump Motor Selection
Fluid viscosity is the biggest non-obvious driver of gear-pump motor selection. Low-viscosity fluids (water, solvents) leak across clearances, dropping…

How Motor Speed Affects Micro Pump Flow Rate
The RPM → displacement → flow chain, and why flow diverges from linearity at the speed extremes.

BLDC Motor vs Brushed DC Motor for Micro Pumps: Which Should You Specify?
For a micro pump, a brushless DC (BLDC) motor is the stronger choice on every axis that matters in compact fluid systems. It delivers longer service life…

Pump Motor Torque: How Much Torque Does a Gear Pump Need?
A gear pump needs torque proportional to pressure and displacement: T ≈ Δp × V / 2π. For compact OEM micro gear pumps (0.6–5 mL/rev), torque is small—typically…

How to Select the Right Motor Speed for a Gear Pump: RPM, Slip & Cavitation
For compact, low-flow micro gear pumps the usable band is typically 800–4000 rpm; for larger industrial gear pumps, 600–1800 rpm. The single most important…

Magnetic Gear Pump vs Conventional Gear Pump: Sealless vs Shaft-Seal Compared
A magnetic gear pump and a conventional gear pump are the same positive-displacement machine — two meshing gears that trap and carry a fixed volume per…
