ROTOR WITH PERMANENT MAGNETS Russian patent published in 2015 - IPC H02K1/27 H02K21/12 

FIELD: electricity.

SUBSTANCE: rotor of electric machine comprises magnet core and permanent magnets placed in pairs inside the magnet core in direct vicinity to its outer surface in circumferential direction. Magnet pairs form the rotor poles. The magnet core is made with crosspieces between its outer surfaces and magnets and neighbouring pairs forming the rotor pairs. At that in the crosspiece made in the magnet core between neighbouring pairs of magnets there are permanent magnets mounted radially and magnetized in tangential direction. The magnet core comprises gaps made over butt end of radial magnets directed towards the side opposite from the rotor rotation axis, slots made perpendicular to butt ends of the magnet poles directed towards the side opposite from the rotor rotation axis and two slots made in the magnet core directly near butt ends of radially mounted permanent magnets directed towards the side of the rotor rotation axis.

EFFECT: increased efficiency of electric machine.
