A wheel hub motor for an electric vehicle includes eight sector-shaped through holes uniformly distributed in the circumference of a disc brake fixed to a shaft, and magnetic conductive ribs made of a magnetic conductive material arranged between two through holes. A stator core consists of nine square-C-shaped sub stator cores, each sub stator core surrounds two sides of the disc brake (6) and is fixed to a vehicle frame, adjacent sub stator cores are different by 30 degrees in a circumferential direction, a concentrated armature winding is wound around a yoke part at the middle portion of the sub stator core. A permanent magnet is fixed to a surface of an inner side of each sub stator core towards the disc brake, the brake caliper is fixed to the vehicle frame and is located at a position without the stator core in a circumferential direction.
