Motors
Hysteresis loss
Electrical equipment; 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. ...
