FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering and can be used in electric machine building in the production of electric motors. Magnetic system of the rotor with incorporated permanent magnets contains prismatic permanent magnets mounted in the rotor magnetic path. On the outer side of the circumference of the magnetic circuit of the rotor there are electrically conductive rods, short-circuited by means of electrically conducting rings located at the ends of the magnetic circuit, with the possibility of providing a synchronous motor with an asynchronous direct start. Incorporated magnets are made in the form of a sector of circles of a hollow cylinder, which form an n-pole magnetic system. According to the first variant, the coupling between the magnets and the magnetic core provides titanium plates rigidly connected to the magnetic circuit by means of a "dovetail" and with electrically conductive rods by means of closed electrically conducting rings located at the ends of the magnetic circuit. In the second variant, the coupling between the incorporated magnets and the rotor magnetic circuit provides short-circuited electrically conductive guides, located at the periphery of the pole divisions, which are rigidly coupled to the rotor magnetic circuit by means of a dovetail connection and with closed electroconductive rings located at the ends of the rotor magnetic circuit.
EFFECT: technical result is an increase in power, mechanical torque, efficiency at a decrease in weight and size indicators.
