成果简介	NOVELTY - The rotor has a rotor core (1) with incorporated permanent magnets (2-4), arranged in groups around a circumference in close proximity to an outer surface of a magnetic circuit. Grooves (8) are made on the outer surface of the magnetic circuit in spaces between poles perpendicular to end parts of the poles. The core is made from a package of thin-sheet laminated electrical isotropic steel plates, electrically insulated from each other. The pole is formed by a group containing three permanent magnets incorporated into the rotor core, located at two levels relative to a rotor rotation axis. Two permanent magnets of identical size and characteristics are located in each group at a level closest to the rotor rotation axis. The permanent magnets are made in form of a set of plates connected to each other in a permanent connection by gluing, where internal cavities (6) are placed with ferromagnetic gaps (5) in the rotor core between the poles. USE - Rotor for an electric machine. ADVANTAGE - The use of groups of individual magnets instead of single magnets of a same volume allows to reduce losses from eddy currents in magnets and to increase length of leakage field closure. The presence of two levels of placement with permanent magnets allows to improve shape of electromotive force in air gap of the electric machine. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a rotor segment. 1Rotor core 2-4Permanent magnets 5Ferromagnetic gaps 6Internal cavities 8Grooves
