ROTOR OF ELECTRIC MOTOR WITH PERMANENT MAGNETS Russian patent published in 2017 - IPC H02K1/27 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, namely to rotor of electric motor with permanent magnets. Rotor (101) of electric motor includes core (102) with permanent magnets (105), end surfaces (105q), which are in contact with main housing parts (117) of magnetic screening parts (107). Extending parts (127) of each magnetic screening part (107) are located in direction to outer periphery of core (102) of rotor (101) from external surface (105ou) of permanent magnet (105) pole between d-axis and q-axis of end surface of rotor core (102).

EFFECT: technical result consists in creation of magnetic field, close to sinusoidal form, reduced pulsation of moment from these harmonics and increasing mechanical strength of rotor core.
