An induction motor may be considered to be a transformer with a rotating short circuited secondary. The stator winding corresponds to transformer primary and rotor winding to transformer secondary. However, the following differences between the two are worth noting: 1. Air Gap Unlike a transformer, the magnetic circuit of a 3-phase induction motor has an air gap. … [Read more...] about Comparison between Induction Motor and Transformer
Single Phase Motors
A stepper motor is an electromechanical device which converts electrical pulses into discrete mechanical movements. The shaft or spindle of a stepper motor rotates in discrete step increments when electrical command pulses are applied to it in the proper sequence. The motors rotation has several direct relationships to these applied input pulses. Types of Stepper … [Read more...] about Types of Stepper Motor
Shaded pole motor is a split phase type single phase induction motor. The shaded pole motor is very popular for ratings below 0.05 HP (~ 40 W) because of its extremely simple construction. It has salient poles on the stator excited by single-phase supply and a squirrel cage rotor. A portion of each pole is surrounded by a short-circuited turn of a copper strip called … [Read more...] about Shaded Pole Induction Motors – Working and Construction

The capacitor start single phase induction motor is a type of split-phase induction motor. Capacitors are used to improve the starting and running performance of the single-phase inductions motors. The capacitor start motor is identical to a split-phase motor except that the starting winding has as many turns as the main winding. Why Single Phase Induction Motor is not … [Read more...] about Capacitor Start Single Phase Induction Motor – Working and Characteristics
