electrical engineering, specifically, electric machines with excitation from permanent magnets. SUBSTANCE: rotor has inert poles 3, 6 made of magnetically soft material and radially magnetized permanent magnets 4, 7 alternating over circumference and installed with fitting to side faces. Rotor is manufactured from two magnetic circuits 1, 2 similar in axial length, shifted through 180 electrical degrees and separated by non-magnetic insert 9. Permanent magnets 4 of one of these magnetic circuits 1 are magnetized in opposite direction and are shifted through 180 electrical degrees with reference to permanent magnets 7 of the other magnetic circuit 2. EFFECT: simplified design of rotor and capability to compensate for leakage flux closing through bearings. 1 dwg
