Abstract: The motor of an anti-lock braking 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 about the teeth and electrically connect to a commutator fixed to a rotor shaft. A bearing is fixed onto one end of the rotor shaft. Pump pistons radially attach to the bearing. The mechanical centreline 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 so that the coils do not overlap with each other. The axial length of the motor is thus reduced.

Abstract: In a method of manufacturing a rotor of a rotary electric machine, a rotor core is formed by preparing a material sheet in a form of a belt. The material sheet has teeth extending from a first side of a middle portion of the material sheet and projections projecting from a second side of the middle portion in a direction opposite to the teeth. The projections define recesses therebetween. Each projection and each recess has substantially the same dimension with respect to a centerline between a first line passing through tops of the projections and a second line passing through bottoms of the recesses. The material sheet is helically wound so that the projections are located on an inner diameter side of a rotor core.

Abstract: The invention relates to a device for fixing permanent magnets inside the cylinder head of a field winding of an electric engine. The inventive device comprises spring clips (12) which are disposed between the permanent magnets in order to ensure the angular positioning and the axial and radial support of said magnets against the inner wall of the head. The end of each clip (12) which first penetrates the head when the permanent magnets are being inserted, comprises means for axially sliding on the inner cylindrical wall of the head, while preventing any contact with an end edge of the clip. Moreover, the clip is set apart from the head by means of at least one boss (17) which is provided on the core (16), and said boss is in turn set back from the edge and disposed between two fins (14) for the axial locking of the magnets.

Abstract: A stator of a direct current motor includes six magnetic poles. An armature of the direct current motor includes an armature core having eight slots, a plurality of windings wound around the armature core as concentrated windings, and a commutator having twenty-four segments connected to the windings. The plurality of windings are connected to one another to form a single closed loop. The direct current motor further includes an anode power supply brush and a cathode power supply brush that slidably contact the segments. The aspect ratio, which is the ratio of the diameter of the armature core with respect to the length in the axial direction of the armature core is set to a range of 3.2 through 5.6. This increases the constraint torque/mass ratio of the direct current motor.
