摘要： A double-stator motor of an example embodiment includes: an annular rotor connected to a rotary shaft and integrally rotates with the rotary shaft, an inner stator arranged radially inward of the rotor, and an outer stator arranged radially outward of the rotor. The rotor includes a plurality of segments annularly arranged in the circumferential direction, spaced apart from each other by a predetermined distance, and a plurality of permanent magnets each interposed between circumferentially adjacent segments, the permanent magnets being alternately magnetized in the circumferentially opposite direction. The rotor, the inner stator and the outer stator have the same number of poles. The inner and outer stator windings of the inner and outer stators, respectively, are connected so that their phases are reversed to each other. Thus, the magnetic fields generated by the magnetomotive forces of the inner and outer stators are applied to specific segments in parallel.

摘要： An electric motor includes a stator, a rotor, and multiple brushes. The stator forms multiple poles. The number of brushes is less than the number of stator poles. The rotor includes a commutator, windings, and equalizing units. The commutator includes segments electrically connected with the windings. Each of the equalizing units is electrically connected with multiple equipotential segments to make the equipotential segments have the same potential. Multiple parallel circuits are formed between the equipotential segments by the equalizing unit. The brushes are arranged to slidably contact the segments of the commutator.

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.
