ROTARY ELECTRIC MACHINE Russian patent published in 2025 - IPC H02K1/276 H02K21/16 

FIELD: electrical engineering.

SUBSTANCE: rotary electrical machine comprises a stator and a rotor, the core of which includes a plurality of sets of permanent magnets. On both sides in direction of rotor rotation relative to each set of permanent magnets there is a first barrier for magnetic flux, as well as a first bridge provided outside the rotor core in a radial direction relative to the first magnetic flux barrier. First bridge includes front and rear bridges. To achieve the technical result, the circumferential position of the rear end of the front bridge is displaced backwards in the direction of rotation relative to the front support location, where the front support location is the point of intersection of the front imaginary line passing through the central axis and the front end along the circumference of the front magnet on the side of the front part of the electrical machine in the direction of rotation, and the outer circumference of the rotor core in the top view.

EFFECT: increased torque of electric machine.
