Ac motors

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. 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

3. 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

4. Construction

5. single phase induction motor Construction Stator- single phase AC supply
