Rotor for a rotating electrical machine

The invention relates to a rotor for a rotating electrical machine, comprising: a central shaft; an annular core coaxial to the shaft; a winding extending radially around the core; a first pole wheel and a second pole wheel arranged axially on each side of the core and the winding. The rotor is characterized in that each pole wheel comprises a plurality of triangular teeth having a base that is tangent to the pole wheel and comprising a first side, denoted a, and a second side, denoted b; the ratio of 1-a/b is between 0 and 0.5, or 0 and -0.5; and the tip of the teeth of one of the pole wheels is equidistant between the ends of the bases adjacent to the tip of the teeth of the other pole wheel. 本发明涉及种用于旋转电机的转子，包括：中心轴；与该轴同轴的环形芯体；围绕所述芯体径向地延伸的绕组；第爪极和第二爪极，轴向地布置在所述芯体和绕组的每侧上。转子的特征在于，每个爪极包括多个三角形齿，其具有与爪极相切的基部并且包括表示为a的第侧和表示为b的第二侧。1-a/b的比率在0至0.5或0至-0.5的范围内；以及爪极之的齿的顶部在与另爪极的齿的顶部相邻的基部的端部之间是等距的。
