<P>PROBLEM TO BE SOLVED: To provide a motor capable of efficiently using magnetic flux from a plurality of permanent magnet pieces and also having good assemblability. <P>SOLUTION: A motor 1 of the present invention includes a plurality of permanent magnet pieces 4a aligned along a rotation direction of a shaft 11 so as to surround an armature core 12, and a magnetic flux guide ring 5 arranged between the permanent magnet pieces 4a and the armature core 12 in order to guide a magnetic flux from the permanent magnet pieces 4a into the armature core 12. The magnetic flux guide ring 5 comprises: opposite parts 5a provided in each permanent magnet piece 4a; holes Ak formed between the opposite parts 5a and arranged at the same positions as boundaries between the permanent magnet pieces 4a; and coupling parts 5b adjacent to the holes Ak and coupling two adjacent opposite parts 5a. <P>COPYRIGHT: (C)2013,JPO&INPIT |
