Motor system including reluctance motor

A motor system includes a reluctance motor and a circuit connected to the reluctance motor. The reluctance motor includes a rotor including N rotor salient poles where N is an integer of 2 or more, a stator including M stator salient poles where M is an integer of 3 or more, 3-phase coils to excite...

More Information
Summary:A motor system includes a reluctance motor and a circuit connected to the reluctance motor. The reluctance motor includes a rotor including N rotor salient poles where N is an integer of 2 or more, a stator including M stator salient poles where M is an integer of 3 or more, 3-phase coils to excite the stator salient poles, and a sensor to detect a rotational position of the rotor. The circuit applies 120-degree conduction to the 3-phase coils when the rotor is rotated in a first direction from a stopped state (initial position), and applies 180-degree conduction to the 3-phase coils when the rotor is rotated in a second direction that is opposite to the first direction from the stopped state.
