The objective of this invention is to provide a motor which can reduce occurrence of a torque reduction in the overload, and also lower the temperature of a motor main body immediately even in the case of a temperature rise in the motor main body. This motor comprises: a stator 20 that is constituted by a stator main body 1 having a plurality of slots 4 formed on the circumference of the main body with equal intervals from each other and teeth 3 each of which is located between the slots 4, and extends outward along the radial direction from the slot bottom face of the slots 4 with the same width, and a coil bobbin 7 that is attached to each of the teeth 3 of the stator main body 1, and is formed by winding a wire 6 around a bobbin 5 that has been preliminarily made from an insulating material such as a resin, in a concentrated winding system; and a rotor 2 that is maintained on the circumference of the stator 20 concentrically with the stator main body 1, in a manner so as to face the stator main body 1 through a predetermined air gap 19.
