Abstract
DC motors using commutators have large rotors because the rotors comprise coils, and the overall size of DC motors is thereby increased. It is therefore difficult to reduce the size of DC motors. In addition, since salient poles of rotors are complex, the cost of the coils is high. The present invention provides a commutator in which slip rings (2) are provided on the sides of the commutator (1), the slip rings (2) are individually connected to the commutator by wires (3) (copper wires etc.), and brushes (4) are disposed on the slip rings (2). Permanent magnets can therefore be used in a rotor and electromagnets can be used in a stator, the current of the stator can be switched by the commutator to which the slip rings are connected, and the motor is thereby completed. As a result, a motor which is smaller and more powerful than conventional motors can be realized.

Since a DC motor using a commutator is wound (coiled) around the rotor, the rotor becomes larger and the whole becomes larger. For this reason, it has become an obstacle to miniaturization. In addition, the winding cost was high because the salient poles of the rotor were complicated.
