Next, a motor generator of a reference form will be described. The motor generator of the reference form is obtained by changing the configuration of the rotor core with respect to the motor generator of the first embodiment. Specifically, the configuration of the members forming the rotor core is changed. Except for the rotor core, the configuration is the same as that of the first embodiment. Therefore, the same components as those in the first embodiment are denoted by the same reference numerals, and the description of the components is omitted unless necessary. Further, since the operation is the same as that of the first embodiment, the description thereof is omitted.

なお、第１〜第６実施形態及び参考形態では、爪状磁極部１１１ｅ、１１１ｉがそれぞれ８個ずつ設けられている例を挙げているが、これに限られるものではない。それぞれ同数設けられていればよい。 In the first to sixth embodiments and the reference embodiment , an example is provided in which eight claw-shaped magnetic pole portions 111e and 111i are provided, but the present invention is not limited to this. It is sufficient if the same number is provided.
