摘要： Disclosed is a motor in which a commutator (10) is provided with connecting wires which short-circuit equipotential segments; brushes (21) are constituted by a low-speed brush (21a), a high-speed brush (21b), and a common brush (21c) used in common by the low-speed and high-speed brushes, and are juxtaposed along the circumferential direction. The circumferential brush width (W2) of the high-speed brush is set to be smaller than the circumferential brush width (W1) of the low-speed brush. The high-speed brush and the low-speed brush are formed so that simultaneous sliding contact with equipotential segments (15) can be avoided. Additionally, armature cores (8) are provided such that a plurality of teeth (12) is point-symmetrical about a rotary shaft (3) at equal intervals in the circumferential direction, and the teeth and slots (13) are formed so as to exist alternately at intervals of 90 degrees in the circumferential direction. By virtue of the above configuration, vibration and noise can be reduced while achieving miniaturization and high performance of a motor.

摘要： A brush-commutated direct-current motor comprises a stator with a plurality of exciter poles, a rotor with a plurality of pole teeth, which is rotatable relative to the stator about an axis of rotation, grooves arranged between the pole teeth, and coil windings arranged on the pole teeth and a commutator which is arranged on the rotor and a plurality of lamellae to which the coil windings are connected. For manufacturing such direct-current motor the coil windings are arranged on the pole teeth in winding cycles, in each of which a coil winding is wound onto each pole tooth. It is provided that on each pole tooth a first coil winding wound around the pole tooth in a first winding direction and a second coil winding wound around the pole tooth in a second winding direction opposite to the first winding direction are arranged.

摘要： The invention describes an electrical machine having an armature with armature slots for accommodating armature coils, and a commutator with commutator laminates. At least one armature coil is formed from two coil elements, which are arranged symmetrically with respect to one another in relation to the axis of rotation of the armature. The electrical machine is designed such that the number of commutator laminates is an integral multiple of the number of armature slots.
