A permanent magnet synchronous motor includes at least two series-connected windings for each phase, and is configured to be driven by selecting the windings using a multi-inverter driving device configured to switch between an inverter for low-speed drive and an inverter for high-speed drive. A ratio of an induced voltage constant of at least one group of windings constituting the windings for the high-speed drive and a d-axis inductance is larger than a ratio of an induced voltage constant of all the series-connected windings to the d-axis inductance.
