Motor Pairing Considerations

Most customers speak to us before purchasing to ensure compatibility with:

  • Load profile: Is the motor driving a constant load, variable load, or shock loads?
  • Duty cycle: Continuous vs intermittent use, peak vs average power demand.
  • Environment: Marine (corrosion, humidity), agriculture (dust, mud), motorsport (heat, vibration).
  • Power/torque curve (does the motor deliver the torque at the speed you need?).
  • Cooling requirements (air vs liquid cooled, ventilation needs).

Contact us for any questions on motor pairing!
