Claims

[Scope of utility model registration request]

(1) A plurality of magnetic pole cores attached to the outer periphery of the body of the rotating shaft, field windings attached to each of these magnetic pole cores, and a field winding placed between these adjacent field windings and attached to the body. , a plurality of coil holders for holding down both field windings and the outside; provided on the body portion spanning below the adjacent field windings, and spaced apart from the coil holders in the axial direction; A plurality of spring holders each having force holes corresponding to the lower portions of both field windings, and a plurality of spring holders fitted into the counterbore holes of these spring holders to press and fix the field windings from below. 1. A salient pole rotor comprising a pressing spring, and wherein the body is provided with an axial ventilation groove twice the amount corresponding to the lower part of the coil presser to form an axial ventilation passage.

(2) The scope of the utility model registration claim, characterized in that the ventilation groove is passed through the body over the entire length in the axial direction, and a spring receiver formed separately from the body is attached to the ventilation groove. The salient pole rotor according to item 1. −

(3) The spring receiver is formed integrally with the body, and the ventilation groove is provided in the axial direction except for the above (the spring receiver is provided in the axial direction except for the above part). Salient pole rotor.
