CAR ENGINE ROTOR STAMPED SHEET WITH PERMANENT MAGNETS AND ITS STRUCTURE WITH INCLINED POLE Russian patent published in 2024 - IPC H02K1/276 H02K1/28 H02K15/03 

FIELD: electrical engineering.

SUBSTANCE: rotor stamped sheet includes an inner stamped sheet and an outer stamped sheet. In the center of the inner stamped sheet there is a mounting hole for attachment and installation of a rotating shaft. On wall of mounting hole for rotating shaft there are multiple key slots, on the outer wall of the inner stamped sheet there are multiple corresponding keys, on the inner wall of the outer stamped sheet there are corresponding keys. Internal and external stamped sheets are rigidly connected by means of interference fit by means of keys and corresponding key slots. On the outer stamped sheet there are first magnetic steel grooves distributed in a circle along the inner side, and the same number of second magnetic steel grooves distributed in a circle along the outer side. On external wall of external stamped sheet in direction of longitudinal axis there are longitudinal grooves, and in direction of transverse axis there are transverse grooves.

EFFECT: reduced pulsation of engine torque and reduced electromagnetic force of the engine.
