ータ。[Claims for Utility Model Registration] A motor is equipped with a stator having a permanent magnet for forming a field and a rotor in which a plurality of rotor windings are wound around a rotor core, and is supported within a motor cover plate. A small motor configured to supply current to the rotor winding through a commutator that is in sliding contact with a power supply brush, and equipped with a positive temperature coefficient thermistor that controls the current to the rotor winding, In addition to fitting the holding base into the motor cover plate,
This holding base is provided with a pair of terminals that penetrate the motor cover plate and protrude to the outer surface, and a pair of brush arms having brushes fixed to their free ends, and are provided with a pair of brush arms that penetrate the motor cover plate and protrude to the outer surface. A positive temperature coefficient thermistor is sandwiched between the holding base and the outer surface of the holding base, and the one terminal and the brush arm are electrically connected, and the other terminal and the brush arm are electrically connected via the positive temperature coefficient thermistor. A small motor equipped with a positive characteristic thermistor.
