ABSTRACT:
An armature for use in a motor has a plurality of teeth, a plurality of slots and coils of three kinds of phases. A plurality of the slots is formed between the coadjacent teeth. The coils of three phases are wound around the teeth. The armature has a coil structure, according to which radial force acting on a specific tooth is greater than radial force acting on another tooth. A peak value of the radial force acting on the specific tooth is approximated to a peak value of the radial force acting on another tooth in such a manner that a flux path in and/or adjacent to the specific tooth is made narrower than a flux path in and/or adjacent to another tooth.
