Abstract

PROBLEM TO BE SOLVED: To provide a motor core which facilitates winding coils on its pole teeth and by which vibrations, etc., at the time of driving can be suppressed. SOLUTION: A belt-type core 1 consists of a plurality of unit yokes 1a, which are connected to each other with linkage parts 1b. The belt-type core 1 is bent into a circle with the respective linkage parts 1b as the centers of bending to form a core main part. Resin parts 5a are formed on the core main part, so as to cover the boundary parts between the adjacent unit yokes 1a and the linkage parts 1b. Consequently, since mechanical connection strength between the unit yokes 1a is improved, coils can be applied to pole teeth 1c easily. Further, as a magnetic connection strength between the unit yokes 1a is improved, electrical characteristics can be improved and vibrations, etc., can be suppressed.

For example, in a stator core, a belt-shaped core in which a plurality of unit yokes are connected to each other via a connecting portion is used, and the band-shaped core is bent from the connecting portion to form an annular core. Forming the body has been performed.
However, simply bending the band-shaped core does not sufficiently connect the unit yokes magnetically and mechanically, so when winding the coil around the magnetic pole teeth of the iron core body, the unit yoke is exposed to external force at the time of winding. There is a possibility that the electrical characteristics are deteriorated due to the positional deviation or the positional deviation of the unit yoke, and vibration and noise are generated. Further, when the unit yokes are welded to each other, since the core body is distorted by the heat generated during welding, a stable magnetic circuit is not formed, and there is a possibility that vibration or the like may occur.
