Abstract

The invention discloses a built-in magnetic steel permanent magnet motor rotor, a motor and a vehicle. The built-in magnetic steel permanent magnet motor rotor comprises an iron core, wherein a plurality of magnetic steel units are arranged in the iron core, each magnetic steel unit comprises a plurality of V-shaped magnetic steels, the V-shaped magnetic steels in the magnetic steel units are arranged in multiple layers from inside to outside, and the number of the V-shaped magnetic steels in each layer is gradually increased from inside to outside. The magnetic steel units comprising the plurality of V-shaped magnetic steels are in a multi-layer wild goose array shape; each magnetic steel unit is equivalent to a magnetic pole with different thicknesses; namely, the magnetic steel unit isequivalent to a magnetic pole; and magnetic steel consumption at the center of the magnetic pole is high, and the magnetic steel consumption on two sides of the magnetic pole is low, so the permanentmagnetic potential distribution of the magnetic poles of the built-in magnetic steel permanent magnet motor rotor in the circumferential range of the iron core is sinusoidal, the salient pole rate ofthe built-in magnetic steel permanent magnet motor is improved, and the magnetic field waveform and flux-weakening speed-expanding capacity of the motor are improved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a built-in magnetic steel permanent magnet motor rotor used for motors in vehicles. Background technique [0002] Electric motors as power sources are the main components of pure electric vehicles and hybrid vehicles. With the development of the trend of full electrification in the transportation field, there are various demands for improving the motors used in pure electric vehicles and hybrid vehicles. The demand characteristics of motors in the field of pure electric vehicles and hybrid vehicles are, first, higher power density, second, higher efficiency, and third, wider speed regulation range. Built-in magnet steel permanent magnet motors are widely used based on their own characteristics to meet the needs of pure electric vehicles and hybrid vehicles. [0003] The rotors of the existing built-in magnet permanent magnet motors are mostly single-layer "V"-shaped, "U"-shaped...
