Abstract:
1. A motor comprising: a stator that is constituted by a stator main body having a plurality of slots formed on the circumference of a main body with equal intervals from each other and teeth each of which is located between the slots, and extends outward along the radial direction from the slot bottom face with a constant width, and a coil bobbin that is attached to each of the teeth of the stator main body, and is formed by winding a wire around a bobbin that has been preliminarily made from an insulating material in a concentrated winding system; and a rotor that has a gear shape and is maintained on the circumference of the stator concentrically with the stator main body, in a manner so as to face the stator through a predetermined air gap, wherein each of said teeth extends beyond an outer circumference of its respective attached coil bobbin toward the rotor.
