Abstract
The invention relates to electric engineering and may be used for synchronous electric machines. A rotor of an electric machine comprises soft-magnetic poles, prismatic magnets, a non-magnetic inside bushing, fixation for poles and magnets, which are made as two non-magnetic cups having C-shaped cross-section, inside of which butt-end parts of poles and magnets are mounted. Each soft-magnetic pole on an active surface of side parts has wedge steps located from different side parts. Points of wedge steps are opposite directed. Width of butt-end part of every step on the rotor active surface equals to tooth point of the stator. Length of every step equals to stator active length. The proposed rotor construction increases reliability of the electrical machine.
