ROTOR OF ELECTRIC MACHINE Russian patent published in 2017 - IPC H02K1/28 H02K1/27 

FIELD: electricity.

SUBSTANCE: rotor comprises a shaft of soft magnetic material in the longitudinal grooves, which are arranged permanent magnets, fixed fixation means in the form of rods, the ends of which are closed in a single loop rings arranged at the ends of the rotor. The fixing means are laid in grooves that are located on the side surfaces of the longitudinal grooves and the permanent magnets opposite each other. The fixing means and rings are made of diamagnetic material, and the permanent magnets in the cross section have a rectangular shape, the outer plane being rounded along the radius of the rotor. Fixing means in the form of rods can reliably fix the magnets in the rotor. Shorted winding of diamagnetic material, and fixation means formed by rings creates conditions for a low-inertia direct starting of synchronous motors.

EFFECT: increasing the magnetic flux and improving the performance of the electrical machine.
