Abstract: The present invention is intended to provide a magnetic gear structure that realizes a magnetic gear that transmits a torque efficiently by reducing eddy currents generated in the interior of magnets. In order to solve the subject described above, in the magnetic gear structure, a structure in which magnets are arranged in the interior of an iron core in an inner rotor portion. Bonded magnets formed by molding, for example, NdFeB powder may be used as the magnets. Since the influence of the eddy current on the side of an outer rotor having a larger pole number is large, a structure in which the magnets are arranged in the interior only of an outer rotor portion having a larger pole number is also applicable. In addition, the magnets to be embedded may be divided into a plurality of pieces. The finer the division of the magnets, the less eddy currents are generated, so that a method of further fining down and assembling the same is also effective. Further reduction of the eddy currents is possible by laminating the plate-shaped magnets having a thickness equivalent to an electromagnetic steel plate in the axial direction.

Abstract translation: 本发明旨在提供一种磁齿轮结构，其实现了通过减少在磁体内部产生的涡流来有效地传递转矩的磁齿轮。 为了解决上述问题，在磁齿轮结构中，在内转子部分中的铁芯内部布置有磁铁的结构。 可以使用通过成型例如NdFeB粉末形成的粘结磁体作为磁体。 由于涡电流对具有较大极数的外转子侧的影响较大，因此也可以仅在具有较大极数的外转子部的内部配置磁铁的结构。 此外，要嵌入的磁体可以被分成多个部分。 磁体的分割越细，产生较少的涡流，因此进一步精细化和组装磁体的方法也是有效的。 通过在轴向上层叠具有与电磁钢板相当的厚度的板状磁体，能够进一步降低涡流。
