Claim 2:
3. The electric motor system according to claim 1, wherein:
the plural-phase windings respectively comprise forward windings and reverse windings which are not directly connected; and
the electric motor system comprises:
a first inverter to which respective first ends of the forward windings are connected, and which applies a current for generating rotating fluxes around the rotor to the forward windings;
a first zero-phase switching arm to which respective second ends of the forward windings are commonly connected, and which adjusts a zero-phase current flowing through a common connection point of the forward windings;
a second inverter to which respective first ends of the reverse windings are connected, and which applies a current for generating rotating fluxes around the rotor to the reverse windings; and
a second zero-phase switching arm to which respective second ends of the reverse windings are commonly connected, and which adjusts a zero-phase current flowing through a common connection point of the reverse windings.
