Description

＜永久磁石およびコイルの配置の説明＞
再び図９および図１０を参照して、シュラウド１２には複数（たとえば８個）の永久磁石１７が埋設されている。複数の永久磁石１７は、隣接する磁極が互いに異なるようにして、等角度間隔で同一の円に沿って隙間を設けて配置される。換言すれば、モータ室８側にＮ極を向けた永久磁石１７と、モータ室８側にＳ極を向けた永久磁石１７とが等角度間隔で隙間を設けて同一の円に沿って交互に配置されている。 <Description of arrangement of permanent magnet and coil>
Referring to FIGS. 9 and 10 again, a plurality of (for example, eight) permanent magnets 17 are embedded in the shroud 12. The plurality of permanent magnets 17 are arranged with gaps along the same circle at equal angular intervals so that adjacent magnetic poles are different from each other. In other words, the permanent magnet 17 with the N pole facing the motor chamber 8 side and the permanent magnet 17 with the S pole facing the motor chamber 8 side are alternately provided along the same circle with gaps provided at equal angular intervals. Has been placed.
