Beschreibung
Zusammenfassung:	A motor system of the present disclosure includes a permanent magnet motor including a stator having N-phase windings and a rotor having a permanent magnet, N being a natural number greater than or equal to three, an inverter that supplies N-phase drive currents for generating a rotating magnetic field to the stator, and a zero-phase current supply unit that supplies a zero-phase current to the N-phase windings of the stator. The motor system applies the zero-phase current to the N-phase windings in response to an inter-terminal voltage of the permanent magnet motor reaching a predetermined value of the inter-terminal voltage.
