摘要： Each permanent magnet formed in an open-letter shape is divided into a plurality of parts, the divided magnets are respectively fitted in open letter-shaped inserting portions, and ribs are respectively provided in dividing portions of the permanent magnets. Accordingly, it is possible to prevent the breakage of pole connecting portions at an outermost periphery of the rotor as adjacent inner peripheral-side permanent magnets directly come into contact with and push the outer peripheral-side permanent magnets. Alternatively, an annular nonmagnetic material is provided on an outer peripheral portion of the rotor so as to cover the open letter-shaped permanent magnets and magnetic material portions inside the open-letter portions, whereby the rotor core is made resistant against breakage, and the flux leakage is minimized.
摘要翻译：形成为开放字形的永磁体被分成多个部分，分割的磁体分别装配在开放字母形的插入部分中，并且在永磁体的分割部分分别设有肋。因此，可以防止在相邻的内周侧永久磁铁直接与外周侧永久磁铁接触并推动外周侧永久磁铁时，在转子的最外周的极连接部的断线。或者，在转子的外周部设置环状非磁性材料，以覆盖开放字母部分内的开放字母形状的永久磁铁和磁性材料部分，从而使转子芯抗破坏，磁通泄漏最小化。
