<p>A motor capable of suppressing the occurrence of lowering of a torque at the time of overloading and immediately lowering the temperature of a motor body even if the temperature of the motor body is increased, comprising a stator (20) having a stator body (1) with a plurality of slots (4) formed equally-spaced in the outer periphery of the body and teeth (3) extending outward from the bottom face sides of the slots (4) with a same width and along the radial direction between the slots (4) and coil bobbins (7) formed by winding, by a concentrated winding system, lead (6) on bobbins (5) formed of an insulator such as a resin beforehand installed on the teeth (3) of the stator body (1), and a rotor (2) held concentrically with the stator body (1) on the outer periphery of the stator (20) and opposed to the stator body (1) through a specified air gap (19).</p> |
