Chapter 13 – AC Motors

AC motors convert AC electrical energy to Mechanical energy. AC motors:
the armature of rotor is a magnet (different to DC motors).
the stator is formed by electromagnets (like in DC motors). Effects of AC Supply on Magnetic Poles Consider the rotor to be a permanent magnet.
Current flowing through conductors energize the magnets and develop N and S poles.
The strength of electromagnets depends on current.
First half cycle current flows in one direction.
Second half cycle it flows in opposite direction
