Abstract
A permanent magnet motor has a rotor and a stator. The rotor has a shaft, a rotor core and commutator fixed to the shaft, and rotor windings wound about poles of the rotor core and electrically connected to the commutator. The stator has an axially extending round housing, a ring magnet member fixed to an inner surface of the round housing, an endcap, and at least one pair of brushes in sliding contact with the commutator. A chamber is formed by the housing and the endcap. The commutator is disposed in the chamber. A window lift device incorporating the motor is also provided.
