Miniature motor having positive-coefficient thermistor

A miniature motor having a positive-coefficient thermistor comprising a stator having a permanent magnet as a field, a rotor formed by winding a plurality of rotor windings on a rotor core;

• current being fed to said rotor windings via a commutator making sliding contact with brushes supported by a motor cover plate, making contact with a commutator;
• and a positive co-efficient thermistor for controlling current to said rotor windings, in which said motor cover plate has a pair of terminal holders for holding terminals;
• said terminals including a pair of terminals made of an electrically conductive material and having engaging and locking portions for engaging with said terminal holders;
• said brushes including a pair of brush arms made of an electrically conductive material;
• connecting members disposed in such a manner as to come in resilient contact with any one of said brush arms and one of said terminals to ensure an electrical connection between said brush arms and said terminals;
• a first supporting member disposed in such a manner as to come in resilient contact with one of said brush arms to electrically connect to said brush arms;
• and ,
• a second supporting member disposed in such a manner as to come in resilient contact with the other one of said terminals are provided in said motor cover plate;
• said positive-coefficient thermistor being held between said first and second supporting members.
