Abstract
PURPOSE: To control electrical and mechanical noises without any additional parts by providing an insulating layer among windings of the coil part formed on the brush base and by holding the coil part with a cylindrical supporter.
CONSTITUTION: The commutator 1 is attached to the rotor shaft 2 of the small DC motor, the bracket 3 and the cylindrical supporter 3a are molded with insulator in a body. The coil 4a is formed on the base of brush 4 and is put onto the supporter 3a of the bracket 3 to hold itself, the insulating thin film 4c that is made thinner as much as possible is provided between the windings of the brush base. Also the rotor shaft 2 is held by the bracket 3 through the bearing 5. In this way, the electrical and mechanical noises produced by the sliding action between the commutator and the brush can be controlled.
