Abstract
A bi-directional single-phase motor includes a stator, a rotor and a control circuit. The rotor is coupled to the stator and rotates along a first direction or a second direction. The control circuit is disposed in the stator and has a first inductive element and a second inductive element. When the first inductive element is on and the second inductive element is off, the rotor rotates along the first direction. When the first inductive element is off and the second inductive element is on, the rotor rotates along the second direction.
