Motors

Torque

Electrical equipment; Motors

Turning force delivered by a motor or gearmotor shaft, usually expressed in lbs. ft derived by completing H.P. x 5250/RPM = full load torque.

Totally-enclosed enclosure

Electrical equipment; Motors

A motor enclosure which prevents free exchange of air between the inside and the outside of the enclosure but is not airtight. Different methods of cooling can be used with this enclosure.

Totally-enclosed air-to-air-cooled machine

A totally enclosed machine cooled by circulating internal air through a heat exchanger which, in turn, is cooled by circulating external air. Provided with an air-to-air heat exchanger for cooling ...

Reluctance synchronous motor

Electrical equipment; Motors

A synchronous motor with a special rotor design which directly lines the rotor up with the rotating magnetic field of the stator, allowing for no slip under load. The reluctance motors have lower ...

Resistance

Electrical equipment; Motors

The degree of obstacle presented by a material to the flow of electric current is known as resistance and is measured in ohms.

Resilient mounting

Electrical equipment; Motors

A suspension system or cushioned mounting designed to reduce the transmission of normal motor noise and vibration to the mounting surface. This type of mounting is typically used in fractional motors ...

Reversing

Electrical equipment; Motors

Unless otherwise specified, a general-purpose DC motor is reversible. A DC motor can be reversed by changing the polarity of the field or the armature, but not both. When rapid reversing is ...
