Choosing the right size
Size a drive on the motor nameplate current at your actual supply voltage, not on kW alone. Constant-torque loads (conveyors, mixers, hoists, compressors) need the heavy-duty / high-overload rating; variable-torque loads (centrifugal fans and pumps) can use the light-duty rating. If you are unsure, send us the motor nameplate details and the application and we will confirm the right Danfoss drive.
