FIELD: electricity.SUBSTANCE: invention relates to a rotor for a motor with built-in permanent magnets, which is used, for example, for electrical vehicles, hybrid vehicles and machines. The rotor for the motor with the built-in permanent magnets comprises an iron rotor core made by layering steel sheets of the base with the density of a magnetic flux of B8000 1.65 T or more when measured at the intensity of the magnetic field of 8000 A/m and coercitive force of 100 A/m and more. The rotor comprises also a multitude of openings for the insertion of permanent magnets placed at a distance from each other at the iron rotor core in a circular direction of the iron rotor core. The permanent magnets are placed in openings intended for the insertion of the permanent magnets.EFFECT: increased output torsion torque within the range of high revolutions.6 cl, 6 dwg |
