Motors

Phase

Electrical equipment; Motors

Indicates the space relationships of windings and changing values of the recurring cycles of A.C. voltages and currents. Due to the positioning (or the phase relationship) of the windings, the ...

Reconnecting a motor's winding in reverse to apply a reverse braking torque to its normal direction of rotation while running. Although it is an effective dynamic braking means in many applications, ...

Totally-enclosed fan-cooled enclosure

Electrical equipment; Motors

Provides for exterior cooling by means of a fan(s) integral with the machine, but external to the enclosed parts.

Totally-enclosed non-ventilated enclosure

Electrical equipment; Motors

Has no provisions for external cooling to the enclosing parts. The motor is cooled by heat radiation from the exterior surfaces to the surrounding atmosphere.

Totally-enclosed pipe ventilated machine

Electrical equipment; Motors

A totally-enclosed machine except for openings so arranged that inlet and outlet ducts or pipes may be connected to them for the admission and discharge of ventilating air. Air may be circulated by ...

Totally-enclosed water air-cooled machine

Electrical equipment; Motors

A totally-enclosed machine cooled by circulating air which, in turn, is cooled by circulating water. Provided with water-cooled heat exchanger for cooling ventilating air and fan or fans, integral ...

Transformer

Electrical equipment; Motors

A device which converts electrical power (alternating current) to electrical power of a different voltage. In this device both primary and secondary windings are usually stationary, and are wound on ...
