Induction Motor
•Inductor is a coil of wire which possess
the property of inductance.
•Inductance is the property of an electric
conductor which generate electromotive force (EMF) by changing the current
flow.
•Induction is the production of electric or
magnetic state without contact in electric or magnetic body.
•Motor converts electrical energy into
mechanical energy in the form of rotation.
•Motor consists of two parts one is stator and second is rotor.
•Stator is a stationary part and rotor is rotary part.
•Both
the stator and rotor are inductively
linked means
there is no direct contact between stator and rotor.
•Induction
motor is a rotating
transformer.
•Machine
is of two types one is synchronous and second is asynchronous.
•Synchronous means stator rotating magnetic
field and rotor rotation is same and asynchronous means stator rotating magnetic
field and rotor rotation is different.
•Electrical
machine are of two types AC (single phase and polyphase) and DC.
•Induction
motor is a asynchronous AC motor it may be single phase or
polyphase.
•Single
phase induction motor is not self starting motor and three phase induction motor is self starting motor.
•Single
phase induction motor are classified as shaded pole induction motor, capacitor start induction motor, capacitor start capacitor run
induction motor, split phase induction motor.
•Three
phase induction motor are classified as slip ring induction motor and squirrel cage induction motor.
