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.
Claims8
An armature for use in a motor, comprising:
- a plurality of teeth;
- a plurality of slots formed between the adjacent teeth;
- and
- coils of three kinds of phases wound around the teeth, wherein 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, and wherein 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 flux paths in and/or adjacent to another tooth.
An iron core for use in an armature of a motor, comprising:
- a plurality of teeth;
- and
- a yoke which connects outer sides of a plurality of the teeth, wherein a specific tooth in a plurality of the teeth is made narrower in flux path than another tooth in such a manner that a hole is formed in the specific tooth and/or in the yoke adjacent to the specific tooth.
An iron core for use in an armature of a motor, comprising:
- a plurality of teeth;
- and
- a yoke which connects outer sides of a plurality of the teeth, wherein each has a body portion radially inwardly extending from the yoke and a wide portion provided at a distal end of the body portion, and wherein a specific tooth in a plurality of the teeth is made narrower in flux path than another tooth in such a manner that a width of the body portion of the specific tooth is partially or wholly made smaller than a width of the body portion of another tooth.
