Starting method of 1 phase I.M.
Split phase starting
Shaded pole starting
types of 1 phase I.M.
Resistor split phase motor
capacitor spit phase motor
Resistor split phase motors have poor starting torque
capacitor split phase motor, capacitor connect series with auxiliary winding make angle 90˚ result in optimum starting torque.
interpoles is widely use to improve commutation
place between main poles fitted to yoke
to neutralize armature mmf in commutating zone
to produce some flux in commutating zone
