Title:
MOTOR
Document Type and Number:
WIPO Patent Application WO/2017/014211
Kind Code:
A1
Abstract:
This motor includes a stator having a winding, and a rotor. The rotor rotates by being subjected to a rotating magnetic field generated when a drive current is supplied to the winding. The winding includes a first winding and a second winding. The first winding and the second winding are energized with the same timing by the drive current, and are connected in series. The rotor includes magnetic poles comprising permanent magnets, and magnetic flux permitting portions. In a rotor rotational position in which the magnetic poles oppose the first winding, the magnetic flux permitting portions oppose the second winding and permit the generation of an interlinkage magnetic flux arising as a result of a weak field current in the second winding.
