Magnetic Field for Single-Phase Motors In order for the rotor to move, the stator must produce a rotating magnetic field. With a single source of AC voltage connected to a single winding, this is not pos-sible. A stationary flux field is created which pulsates in strength as the AC voltage varies, but it does not rotate.
