Ac motors
1. AC Motors
•Electric motors which run on AC supply .
•Classification
•Universal motor
•Induction motor
•Synchronous motors
•Universal Motors:
•Run on AC and DC supply
•Construction
•working
2.
3. Induction motor
• Construction and working principle.
• Motor Speed less than the synchronous speed.
• Synchronous speed- speed of the rotating magnetic field.
• SINGLE PHASE INDUCTION MOTOR – Not Self Starting
• THREE PHASE INDUCTION MOTOR –Self Strating
4. Three phase induction motor
• Construction:
Stator: made up of numbers of slots to construct a 3 phase winding circuit
which is connected to 3 phase AC source.
Rotor:cylindrical laminated core with parallel slots that can carry conductors
• Working
