1. Differentiate the working principle of Direct-Current Motor, Single-Phase Motor and Three-Phase Induction Motor. Please use suitable diagram. [25 Marks) 2. Determine the synchronous speed of a 3-phase induction motor having 20 poles when it is conne...
A shaded pole motor is a single-phase induction AC motor. The secondary winding composed of a copper ring is called a shaded pole coil. In order to provide a magnetic field to the rotor, the current in this coil delays the magnetic flux of that part of the pole. The direction of rotat...
Fans are made of an electric motor and rotor blades. The fan is usually a single-phase induction motor and the rotor blades are optimized aerodynamically. The fan uses electricity to rotate the blades which then drive air in the room ventilating it....
