Motors

The part of the motor housing which supports the bearing and acts as a protective guard to the electrical and rotating parts inside the motor. This part is frequently called the "end bracket" or "end ...

Armature reaction

Electrical equipment; Motors

The current that flows in the armature winding of a DC motor tends to produce magnetic flux in addition to that produced by the field current. This effect, which reduces the torque capacity, is ...

Constant speed

Electrical equipment; Motors

A DC motor which changes speed only slightly from a no load to a full load condition. In AC motors, these are synchronous motors.

Core

Electrical equipment; Motors

The iron portion of the stator and rotor; made up of cylindrical laminated electric steel. The stator and rotor cores are concentric separated by an air gap, with the rotor core being the smaller of ...

Counter electromotive force(CEMF)

Electrical equipment; Motors

The induced voltage in a motor armature, caused by conductors moving through or "cutting" field magnetic flux. This induced voltage opposes the armature current and tends to reduce it.
