Windscreen wiper motor structure

The utility model provides a windscreen wiper motor structure, relates to wiper or similar device. Fold certain angle that staggers between rotor punching and the rotor punching and press together, after folding and press, a plurality of rotor punchings form the pyriform metallic channel, it is the chute structure that rotor punching pile pressure in -process changes the straight flute structure, along the motor shaft to, the metallic channel is in the angle in a rotatory groove of circumferencial direction, traditional motor form is continued to use to other parts of motor, the cost does not increase, the air gap field has still been optimized, winding back electromotive force higher harmonic has been reduced, the tooth's socket torque has been weakened, reduce electric magnetic vibration, reduce motor noise, improve riding comfort.
