ROTOR MAGNETIC SYSTEM Russian patent published in 2021 - IPC H02K1/27 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, to the design of the magnetic systems of the rotors of electric machines with excitation from permanent magnets and can be used in electrical engineering in the production of electric motors and generators. The rotor magnetic system contains permanent magnets installed in two rows and made with different permissible operating temperatures. The upper row is made of high-temperature permanent magnets with the ability to reduce losses for eddy currents and hysteresis, and the lower row is made of one-piece permanent magnets with higher energy characteristics, but with a lower operating temperature and is located in the axial direction with alternating poles.

EFFECT: increases energy properties of the rotor magnetic system.
