AC
motor
•AC
motor have two types one is Induction
motor and
second is synchronous
motor.
•Induction
motor have two types one is single phase induction motor and second is three
phase induction motor.
•Single
phase induction motor is not self starting and three phase induction motor is
self starting.
•Based
on starting method single phase induction motor is further divided into four
types one is Split phase induction motor second is shaded pole induction motor
and third is capacitor start induction motor and fourth is capacitor start
capacitor run induction motor.
•Three
phase induction motor have two types of rotor one is slipring type and second
is squirrel cage type.
•Synchronous
means rotating magnetic field and rotor rotation speed is same.
•Synchronous
motor have both AC and DC supply stator have three phase AC supply and rotor
have DC supply.
•Synchronous
motor is use for constant speed.
•Synchronous
motor
have two types of rotor one is salient pole (low speed) and second is non
salient pole (high speed) rotor.
•Synchronous
motor is use for constant speed motor purpose and it is also use for power
factor improvement device (called synchronous condenser).
•Synchronous
motor is not self starting motor so using
external motor or we have to start it as induction motor.
