Motors

The resistance offered by materials to becoming magnetised (magnetic orientation of molecular structure) results in energy being expended and corresponding loss. Hysteresis loss in a magnetic circuit ...

Identification

Electrical equipment; Motors

In most instances, the following information will help identify a motor: 1. Frame designation (actual frame size in which the motor is built). 2. Horsepower, speed, design and enclosure. 3. Voltage, ...

Inductance

Electrical equipment; Motors

The characteristic of an electric circuit by which varying current in it produces a varying magnetic field which causes voltages in the same circuit or in a nearby circuit.

Induction motor

Electrical equipment; Motors

An induction motor is an alternating current motor in which the primary winding on one member (usually the stator) is connected to the power source and a secondary winding or a squirrel-cage ...

Inertial load

Electrical equipment; Motors

A load (flywheel, fan, etc.) which tends to cause the motor shaft to continue to rotate after the power has been removed (stored kinetic energy). If this continued rotation cannot be tolerated, some ...

Insulator

Electrical equipment; Motors

A material which tends to resist the flow of electric current (paper, glass, etc.) In a motor the insulation serves two basic functions: 1. Separates the various electrical components from one ...

Insulation systems

Electrical equipment; Motors

Five specialised elements are used, which together constitute the motor's INSULATION SYSTEM. The following are typical in an AC motor: 1. TURN-TO-TURN INSULATION between separate wires in each coil. ...
