摘要： A rotor includes permanent magnets arranged such that magnetic poles of N poles and S poles are arranged alternately in a rotation circumferential direction. The permanent magnets form a plurality of rows in a rotation axis direction. The rotor includes a change section in which arrangements of the magnetic poles change with respect to the rotation axis direction due to the permanent magnets being arranged such that arrangements of the magnetic poles change, in the rotation circumferential direction, between the permanent magnets in the plurality of rows. A stator includes tooth sections opposed to the rotor to surround the rotor, and auxiliary slots each of which is selectively formed at one portion of a front end portion of each tooth section in the rotation axis direction such that substantially a center of the auxiliary slot in the rotation axis direction is opposed to the change section.
摘要翻译：转子包括设置成使得N极和S极的磁极沿旋转圆周方向交替布置的永磁体。永磁体在旋转轴方向上形成多列。转子包括变化部，其中由于永磁体被布置成使得磁极的配置在旋转圆周方向上在多个永磁体之间变化，磁极的配置相对于旋转轴线方向变化的行。定子包括与转子相对的围绕转子的齿部分，以及辅助槽，每个辅助槽在旋转轴线方向上选择性地形成在每个齿部的前端部分的一部分处，使得基本上辅助槽的中心位于旋转轴方向与变更部相对。
