The cooling type determines the motor’s continuous torque capacity during sustained operation. The increased thermal dissipation from surface or liquid cooling allows higher torque output without thermal derating.

The continuous current depends on the winding resistance and thermal management during zero-speed torque production. The lower winding temperature achieved through liquid cooling improves efficiency and current tolerance.

The winding inductivity defines the current ripple and affects drive controller tuning stability. The controller must compensate for inductance lag to maintain precise torque response.

The rated frequency aligns with the motor’s magnetic design to ensure consistent field rotation. The mismatch between inverter output and rated frequency may cause torque pulsations.

The permissible ambient temperature and altitude determine heat dissipation and insulation life expectancy. The restricted operating range ensures stable torque and protects winding insulation from degradation.
