The class of motor insulation for a given motor. The temperature capabilities of each insulation class is defined as being the maximum temperature at which the insulation can be operated to yield an average life of 2, hours (A = 15?C, B = 135?C, F =
Indicates the space relationships of windings and changing values of the recurring cycles of AC voltages and currents. The most common power supplies are either single- or three-phase.
The force that causes a current to flow in an electrical circuit. The voltage of a motor is usually determined by the supply to which it is attached. NEMA requires that motor be able to carry its rated horsepower at nameplate voltage plus or minus 1% al
This is a feature which protects the motor from overheating and thus prolongs service life of the machine. In the event that the motor approaches overheating the thermal protection cuts power and only returns it after a cooling period.
