i have two questions:-1) What is the main difference between an AC and DC motors in their construction?2) What makes an induction motor-turn?
1) DC motors have a commutator whilst AC motors do not. 2). The torque generated by current in the stator winding reacting with the magnetic field produced by current in the rotor. In the induction motor the rotor current is driven by voltage induced by the field produced by the stator winding currents - hence the name induction motor.
