ELECTRIC MACHINE WITH ROTOR MADE AS PER HALBACH CIRCUIT Russian patent published in 2020 - IPC H02K21/12 H02K16/02 H02K1/27 

FIELD: electrical engineering.

SUBSTANCE: electric machine with a rotor made according to the Halbach scheme includes a winding assembly consisting of a plurality of coils, wherein a plurality of coils are arranged in the form of a ring, and a rotor including a plurality of external magnets in form of an external Halbach ring, a plurality of internal magnets, made in form of internal Halbach ring, note here that winding is arranged between multiple inner and outer magnets. Magnets of the external Halbach ring have the following sequence of magnetization direction: tangentially, counterclockwise; radially from center; tangentially, clockwise; radially to center. In the inner Halbach ring, the magnets are magnetized in the following order: tangentially, clockwise; radially from center; tangentially, counterclockwise; radially to center. Directions of magnetization on inner and outer rings of Halbach are matched so that magnetic flux created by permanent magnets of inner and outer rings is added.

EFFECT: improved energy characteristics.
