Abstract
A washing machine capable of independently driving two rotors using one inverter in a simple configuration without supplying a composite current includes an outer rotor having a plurality of switching magnets arranged at intervals in the circumferential direction, and an inner rotor having a plurality of stationary magnets arranged to be radially arranged at intervals in the circumferential direction. When a magnetizing current is supplied to the coil of the stator, the magnetic pole of the switching magnet is inverted and the number of the poles of the outer rotor is switched.
