FIELD: electrical engineering.
SUBSTANCE: invention relates to electric machine rotor. Rotor for electric rotary machine comprises rotor core with at least one section with low rigidity, multiple magnets, rotor shaft, washer tightly contacting with at least one end surface of rotor core determined in axial direction and nut. Outer peripheral end of washer is located in radial direction closer to centre of rotation, than holes for magnets. Washer has outer circumferential shape with recesses and projections, in which distance from centre of rotation to outer peripheral end of washer varies periodically. Distance from the outer peripheral end of the washer to each section with low stiffness is greater than the distance from the outer peripheral end of the washer to each hole for the magnet.
EFFECT: technical result is higher reliability of rotor.
