DC motor with a positive temperature coefficient thermistor

A motor comprising:

• a motor frame;
• a shaft rotatably supported by the motor frame and extended in an axial direction;
• a bracket attached to the motor frame and including a penetration hole through which the shaft is passed and a groove;
• a positive temperature coefficient (PTC) thermistor having a first major planar surface and a second major planar surface opposite to the first surface, a first electrode portion is disposed on the first major planar surface and a second electrode portion is disposed on the same first major planar surface;
• a first terminal arranged in the groove and attached to a brush;
• and
• a second terminal arranged in the groove and arranged at a position away from the first terminal, the second terminal being configured to be coupled with an external terminal,
• wherein on the first major planar surface, the first electrode portion of the PTC thermistor is coupled to the first terminal and the second electrode portion of the PTC thermistor is coupled to the second terminal.

A motor comprising:

• a motor frame;
• a shaft rotatably supported by the motor frame and extended in an axial direction;
• and
• a bracket assembly attached to the motor frame,
• wherein the bracket assembly comprises:
• a bracket body having a penetration hole and a groove, the shaft is passed through the penetration hole;
• a first terminal arranged in the groove;
• a second terminal arranged in the groove;
• and
• a positive temperature coefficient (PTC) thermistor having a first major planar surface and a second major planar surface opposite to the first surface and arranged in the groove so that the first and second major planar surfaces are arranged at a plane parallel to the axial direction, only one of the first and second major planar surfaces being faced to both of the first and second terminals.
