ム１側に磁束が漏洩するおそれはない。 In the above configuration, a magnetic flux is formed between the rotor 24 and the field core 28 during power generation, but since the second bearing holder 22 and each screw 31 are made of a non-magnetic material, the magnetic flux is transmitted to the second frame. There is no leakage to the second side. In addition, the first bearing holder 18
Since it is also made of a non-magnetic material, there is no risk of magnetic flux leaking to the first frame 1 side.

Although the magnetic flux leaks to the second frame 2 side through the screw 31 to some extent, this does not cause any practical problems.
