It is fixed by a field winding 3 formed by winding a wire around the outer diameter side of the field winding 3. A total of six cooling fins 4 are provided, three on each side of the magnetic pole core 1. Since the cooling fins 4 are fixed to the magnetic pole core 1 by the field winding 3 made of wire wound around the outside of the support plate 4b, there is no fear that the cooling fins 4 will pop out due to centrifugal force accompanying rotation.

の製作を簡単にすることができる。According to this invention, cooling fins are provided which are made up of an elongated support plate and a flat plate extending in a direction perpendicular to the support plate,
The support plate of the cooling fin is brought into contact with the magnetic pole insulation of the magnetic pole core, and a field winding is formed by winding a wire around the outside of the support plate.
Since the cooling fins are fixed to the magnetic pole iron core by the field winding,
There is no fear that the cooling fins will pop out due to centrifugal force. Also,
Since the cooling fins are inserted all the way to the inside of the field winding,
The cooling area of the cooling fins is increased to improve the cooling effect of the field winding. In addition, if cooling fins with a U-shaped cross section are used, the support plate is in contact with the magnetic pole insulation, and the wire is wound between the opposing flat plates to form a field winding, and the cooling fins are fixed, so centrifugal force is reduced. There is no danger of the cooling fins flying out. Furthermore, since the cooling fins penetrate inside the field winding, the cooling area is expanded and the cooling effect of the field winding is improved. Note that if cooling fins having a truncated cross section are used, the field winding is formed by winding wires on the outside of the support plate, and the cooling fins are fixed, so there is no fear that the cooling fins will fly out due to centrifugal force. Furthermore, since the cooling fins are inserted to the inside of the field winding, the cooling area of the cooling fins is increased and the cooling effect of the field winding is improved. Furthermore, manufacturing of the cooling fins can be simplified.
