MOTOR

摘要

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.
