<p><P>PROBLEM TO BE SOLVED: To provide an anti-lock brake system for a vehicle, and to provide an electric motor used for the anti-lock brake system. <P>SOLUTION: The motor of the anti-lock brake system comprises a stator having six stator poles and a rotor with a rotor core having nine teeth. The rotor is rotatably mounted to the stator with the rotor core confronting the stator poles. Rotor windings are wound around the teeth and electrically connected to a commutator fixed to a rotor shaft. A bearing is fixed to one end of the rotor shaft. Pump pistons are radially attached to the bearing. The mechanical centerline of the bearing is offset from the rotational axis of the rotor shaft so that the pistons are driven by the bearing when the rotor turns. The windings comprise a plurality of concentrated coils where the coils do not overlap with each other. The axial length of the motor is thus reduced. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
