ABSTRACT:
Magnetic fluid is inserted between slip rings of a rotor and brushes of a stator. The magnetic fluid is held by magnetic force generated by permanent magnets and yokes mounted on the stator, so as to be sidable relative to the slip rings. In this state, in accordance with rotation of the rotor, the brushes and the slip rings are rotated without direct contact with each other via the magnetic fluid. Thus, the brushes and the slip rings are electrically connected to each other.
