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.

couplings

Electrical equipment; Motors

The mechanical connector joining the motor shaft to the equipment to be driven.

current

Electrical equipment; Motors

The time rate of flow of electrical charge and is measured in amps (amperes).

cycles per second (hertz)

Electrical equipment; Motors

One complete reverse of flow of alternating current per rate of time. (A measure of frequency.) 60 HZ (cycles per second) A.C. power is common throughout the U.S. and 50 HZ is more common in some ...
