Abstract

PURPOSE:To stabilize the potential of the load which is connected to a rotating member by grounding a rotary shaft so as not to transmit electrical noises to the rotating member. CONSTITUTION:A current which is fed by lead wires 10 is supplied to a rotor 2 formed by a center-void coil through a current-feeding brush 9 and a commutator 8, and the rotor 2 is rotated by the magnetic field generated by a stator magnet 3 and the center-void coil. A rotary shaft 1 is rotated by the rotation of the rotor 2, and a driving force is given to a load. The potential of the rotary shaft 1 is maintained at the ground potential through a slip ring 6, a grounding brush 7, and a grounding lead wire 11. Therefore, electrical noises caused by the current induced in the rotary shaft are not transmitted to the load connected to the rotary shaft.
