Motors

Canopy (dripcover)

Electrical equipment; Motors

A protective cover placed on the top of a motor being mounted vertically to protect it from liquids or solids that might drop onto the motor. (It acts similar to an umbrella for the motor.

The rate at which alternating current makes a complete cycle of reversals. It is expressed in cycles per second. In the U.S. 60 cycles (Hz) is the standard while in other countries 50 Hz (cycles) is ...

Capacitor

Electrical equipment; Motors

A device which, when connected in an alternating-current circuit, causes the current to lead the voltage in time phase. The peak of the current wave is reached ahead of the peak of the voltage wave. ...

Front end of a motor

Electrical equipment; Motors

The front end of a normal motor is the end opposite the coupling or driving pulley. (NEMA) This is sometimes called the opposite pulley end (O.P.E.) or commutator end (C.E.).

Capacitor motor

Electrical equipment; Motors

A single-phase induction motor with a main winding arranged for direct connexion to the power source, and auxiliary winding connected in series with a capacitor. There are three types of capacitor ...

Full-load current

Electrical equipment; Motors

The current flowing through the line when the motor is operating at full-load torque and full-load speed with rated frequency and voltage applied to the motor terminals.

Capacitor start

Electrical equipment; Motors

The capacitor start single phase motor is basically the same as the split phase start, except that it has a capacitor in series with the starting winding. The addition of the capacitor provides a ...
