Motors

peak torque (Tpk)

Electrical equipment; Motors

The maximum torque capability of a motor based on the maximum current limit (I m ). Tpk = K t I m .

power dissipated (PD)

Electrical equipment; Motors

Power loss due to energy expended in the motor stator and rotor. It appears as heat and is expressed in watts. P d = P in -P o

pull-in torque

Electrical equipment; Motors

(Synchronous motors) Pull-in torque is obtained by starting the motor from rest at a pre-set torque value and specified motor terminal voltage. The maximum torque setting which the motor will ...

pull-out torque

Electrical equipment; Motors

(Synchronous motors) Pull-out torque is obtained by steadily increasing the load torque from the normal operating range of a synchronous motor while maintaining specified terminal voltage. The ...

pull-up torque

Electrical equipment; Motors

(Induction motors) Pull-up torque is obtained by starting the motor from rest at a pre-set torque value and specified motor terminal voltage. The maximum torque setting which the motor will ...

rotor

Electrical equipment; Motors

The rotating element of the magnetic structure which is found in non-commutator machines.

skew

Electrical equipment; Motors

The angular displacement of the rotor or armature slots from one end to the other. It can be expressed in terms of the angular displacement from parallel. It can be expressed in degrees, bars or ...
