AC Motors:

An electric motor which required an AC power supply are the AC Motors. AC Motors are having some below Categories: Single Phase, Three phase, Synchronous, Special Purpose Motors and Before we start Induction Motors first lets know what are the advantages are there over DC Motors of induction Motors:-

Ø The main advantage of induction Motors is that its lower cost in market due to which DC Motors are replaced by Induction Motors

Ø Size, shape and light weight

Ø Induction Motors can be operated in any atmospheric environments alongwith explosive conditions because brushes are not used in it so therefore there is no sparking issues.

Ø Induction motor rotates an much higher speed than that of DC motors its around 12000RPM

Ø Speed of an Induction Motor using a thyristor gives wide range of speed to it.
