Polyphase (three-phase) induction motors have a high starting torque, power factor, high efficiency, and low current. They do not use a switch, capacitor, relays, etc., and are suitable for larger commercial and industrial applications. Polyphase induction motors are specified by their electrical design type: A, B, C, D or E, as defined by the National Electrical […]

Types of single-phase motors are distinguished mostly by the way they are started and the torque they develop. Shaded Pole motors have low starting torque, low cost, low efficiency, and no capacitors. There is no start switch. These motors are used on small direct drive fans and blowers found in homes. Shaded pole motors should

The electric motor in its simplest terms is a converter of electrical energy to useful mechanical energy. The electric motor has played a leading role in the high productivity of modern industry, and it is therefore directly responsible for the high standard of living being enjoyed throughout the industrialized world. An electric motor’s principle of
