Abstract

PURPOSE:To facilitate the repair of the commutator unit and to prevent the occurrence of spark during commutation by detachably providing the commutator to a motor body and providing the auxiliary contact piece having a predesigned circuit to the contact piece provided to the commutator. CONSTITUTION:In order to supply a current to an armature winding 10 by energizing a solid rotor coupled through nonmagnetic unit 3 to right and left rotary magnetic field iron cores 2, 1 and providing the winding 10 at the stationary side, a detachable commutator body 20 and a contact piece disk 40 rotating integrally with the rotating shaft 5 are provided at the motor body. Two adjacent contact pieces 42 are disposed at the disk 40. When the disk 40 moves, for example, rightwardly, it is provided to connect a high resistor 61 in the left side circuit of the contact piece 42. Thus, when the circuit of the left side contact piece 42 and the commutator brush 25 provided at the commutator body 20 are interrupted, the circuit having high resistance makes contact, thereby preventing the spark.
