Motors

Brakes

Electrical equipment; Motors

An external device or accessory that brings a running motor to a standstill and/or holds a load. Can be added to a motor or incorporated.

A type of coil in which each winding is individually formed and placed into the stator slot. A cross sectional view of the winding would be rectangular. Usually form winding is used on high voltage, ...

Braking torque

Electrical equipment; Motors

The torque required to bring a motor down to a standstill. The term is also used to describe the torque developed by a motor during dynamic braking conditions.

Fractional-horsepower motor

Electrical equipment; Motors

A motor usually built in a frame smaller than that having a continuous rating of one horsepower, open construction, at 1700 -1800 rpm. Within NEMA frame sizes FHP encompasses the 42, 48 and 56 ...

Frame

Electrical equipment; Motors

The supporting structure for the stator parts of an AC motor; in a DC motor the frame usually forms a part of the magnetic coil. The frame also determines mounting dimensions (see frame size).

Breakdown torque

Electrical equipment; Motors

The maximum torque a motor will develop at rated voltage without a relatively abrupt drop or loss in speed.

Frame size

Electrical equipment; Motors

Refers to a set of physical dimensions of motors as established by NEMA. These dimensions include critical mounting dimensions. 48 and 56 frame motors are considered fractional horsepower sizes even ...
