Patent Searching and Data


Title:
磁気回路構造、これを用いた発電装置、モータ、及び電子機器
Document Type and Number:
Japanese Patent JP3610906
Kind Code:
B2
Abstract:
Convex and concave structures formed in an end portion 22b of a stator yoke 22 and an end portion 23b of a magnetic core 23 are mated in a staggered manner and are joined. An upper projecting portion 22b-1 of the stator yoke 22 is fitted in a recessed portion formed on a lower projecting portion 23b-2 of the magnetic core 23, and the lower projecting portion 23b-2 of the magnetic core 23 is fitted in a recessed portion formed under the upper projecting portion 22b-1 of the stator yoke 22. In this state, the stator yoke 22 and the magnetic core 23 are fixedly fastened by a joint screw 24 and a tube 26. This structure makes it possible to reduce magnetic resistance in a magnetic circuit structure and to improve power-generating efficiency of a power-generating device using the structure.
