BLOCK OF MAGNETS Russian patent published in 2018 - IPC H02K1/27 H02K29/03 

FIELD: electrical equipment.

SUBSTANCE: invention relates to electrical equipment. Electric machine with permanent magnets comprises annular stator with circumferentially distributed multiphase winding and cylindrical rotor, including the non-magnetic shaft and circumferentially distributed poles, containing magnetized in the tangential direction prismatic permanent magnets. Distributed around the circumference rotor poles are cylindrical shells, in which magnetized in the tangential direction permanent prismatic magnets are installed. Magnet in the pole fixing device is made in the form of enclosing the magnet cylindrical case, which walls from the ends and from the shaft side are made of non-ferromagnetic material. Case is installed inside the pole shell and fixed between the flanges. Rotor poles are fixed from the rotor ends with possibility of their extension in the axial direction.

EFFECT: technical result consists in increase in the rotor with permanent magnets manufacturability and poles with permanent magnets into the rotor installation simplification.
