Claims

[Scope of utility model registration request]

Support arms are arranged in the axial direction at multiple locations on the outer circumference of the spider rim of the rotor in the circumferential direction, and key grooves in the axial direction are provided on the outer circumference of each of these support arms. A large number of extracted rim plates are arranged in the circumferential direction, and the seams are shifted in the circumferential direction by one magnetic pole pitch for each layer, and are laminated to form an integrated cylindrical layered rim, and this layered rim has an inner circle. A large number of key grooves are provided around the periphery, which are fitted into each support arm of the spike rim, and a key is driven into and connected between the corresponding key grooves of both sides, and the outer circumference of the layered rim is In a salient pole type rotor in which a large number of magnetic poles are arranged and fixed on the support arm, one pitch of the keys of the stratified rim corresponds to the least common multiple of the number of magnetic poles and the number of keys of the support arm. A salient pole for a rotating electrical machine, characterized in that the key grooves on the arm are arranged in order by increasing and decreasing the interval between them, and the number of key grooves on the stratified rim is half of the least common multiple, and the key grooves are arranged at equal intervals. shaped rotor.
