Step forward motor single pulse/double pulse?
One coil is one phase, three coils, so three.I hope my answer will help you.
Refers to when the motor three-phase three-phase motor stator winding Angle of 120 degrees (the difference between electric), pass into the three-phase alternating current (ac), will produce a rotating magnetic field, the rotating magnetic field cutting rotor winding, thus produce induced current in the rotor winding, rotor winding is closed path).
The motor is in the circuit with the letter "G". Its main function is to use mechanical energy to convert into electricity, and the most commonly used is to use heat energy and water energy to push the rotor of the generator to generate electricity.
