Abstract:
A rotor in a rotary electric machine, comprising:a plurality of slots which are formed axially of the rotor; windings which are inserted into said slots; wedges for holding said windings which are fitted in said slots, said wedges each having slant faces formed at a predetermined angle relative to a radial direction of an iron core of the rotor; and teeth which are formed between adjacent said slots, said teeth having slant faces for abutment against said slant faces of said wedges to retain the wedges each in a fitted state between adjacent said teeth, a rising position of each said slant face in said teeth being formed in an arcuate shape; wherein, in a predetermined number of said teeth which are located near magnetic pole portions in said rotor core portion, the arcuate shape at each said slant face rising position has a radius of curvature larger than that of the arcuate shape at each said slant face rising position in the remaining teeth.
