Abstract

The present disclosure includes a washing machine including an inner rotor and an outer rotor. An outer rotor and an inner rotor may be rotated in a synchronous rotation mode or a counter rotation mode by converting the number of magnetic poles of the outer rotor. When the outer rotor becomes inoperable when the outer rotor is set to the number of magnetic poles for performing the counter rotation mode, it is converted to the number of magnetic poles for performing the synchronous rotation mode while the outer rotor is stopped.
