FIELD: machine building.
SUBSTANCE: invention relates to electric machine engineering and can be used in electric machines with permanent magnets. Electric machine rotor comprises shaft of magnetically soft material, permanent magnets arranged in lengthwise grooves and annular contour of diamagnetic material. Lengthwise grooves are made in annular circuit. Lateral longitudinal plane of the magnet is parallel to the plane passing through the longitudinal axis of the rotor and the lower face of the opposite to the longitudinal plane of the magnet. Circular loop can be rigidly fixed on cylindrical insert of imbedded electrical steel fixed on steel shaft.
EFFECT: technical result is increased magnetic flux and improved performance of electrical machine.
