Electrical equipment; Motors

An electronic device that converts fixed frequency and fixed voltages to variable frequency and voltage. Enables the user to electrically vary the speed of an AC motor.

jackscrew

Electrical equipment; Motors

A device used for leveling the positioning of a motor. These devices are adjustable screws fitting on the base or motor frame. Also a device for removing endshields from a motor assembly.

Since the watt is a relatively small unit of power, the kilowatt (kw), 1,000 watts, is used where larger units of power measurements are desirable.

locked rotor current

Electrical equipment; Motors

Steady state current taken from the line with the rotor at standstill (at rated voltage and frequency). This is the current seen when starting the motor and load.

locked rotor torque

Electrical equipment; Motors

The minimum torque that a motor will develop at rest for all angular positions of the rotor (with rated voltage applied at rated frequency).

A motor converts electrical energy into a mechanical energy and in so doing, encounters losses. These losses are all the energy that is put into a motor and not transformed to usable power but are ...
