The motor which runs at synchronous speed is known as the synchronous motor. The synchronous speed is the constant speed at which motor generates the electromotive force. The synchronous motor is used for converting the electrical energy into mechanical energy.
An induction motor may be considered to be a transformer with a rotating short-circuited secondary. The stator winding corresponds to the transformer primary and the rotor winding to the transformer
1. A synchronous motor can operate at (A) Lagging power factor only (B) Leading power factor only (C) Unity power factor only (D) Lagging, leading and unity power factor only
Electric Motors need maintenance regularly in order to avoid failure and prolong their lifespan. Generally, motors and motor parts should be maintained and tested at least every 6 months. Then
Insulation Resistance or IR Test is carried out by maintenance engineers to ensure the healthiness of the overall insulation system of electrical equipment. It reflects the presence or absence of
Before going to the operation and characteristics of split-phase induction motor we should first understand why single phase induction motor is not self-starting. To make a single-phase induction motor self-starting,
Single-phase motors are the most familiar of all-electric motors because they are extensively used in home appliances, shops, offices etc. It is true that single-phase motors are a less efficient
