ELECTRIC MOTOR, HOISTING MECHANISM AND LIFT SYSTEM Russian patent published in 2015 - IPC H02K1/27 H02K26/00 B66B9/16 B66B11/00 

FIELD: electricity.

SUBSTANCE: invention is related to electric engineering, and namely to electric motors and mechanisms using them. The electric motor comprises stator; at that stator has slots (5) with concentrated winding installed in it. Besides, the electric motor comprises rotating rotor; moreover the rotor comprises permanent magnets placed in circumferential direction towards rotational motion. Ratio (L_M/L_R) of the permanent magnet width at the point (L_M) of the magnet central line and width (L_R) of the rotor magnet pole is equal at least to 2/3 and less than 4/5.

EFFECT: effective usage of inner space of the electric motor with permanent magnets, wherein vibration and noise generated by magnetic field harmonics are reduced by corrected placement and shape of permanent magnets at reduced pulsation of torsion torque and provided noiseless operation.
