Abstract

The invention provides a rotor structure, a permanent magnetism auxiliary synchronization magnetic resistance motor and an electric vehicle; the rotor structure comprises a rotor body having a magnetic steel slot set; the magnetic steel slot set comprises inner magnetic steel slots; the rotor body is also provided with a first fold slot and a second fold slot; the first fold slot is connected witha first end of the inner magnetic steel slot; the geometric center line of the first fold slot in the length direction and that of the first end of the inner magnetic steel slot in the length direction form a first inclined angle; the second fold slot is connected with a second end of the inner magnetic steel slot; the geometric center line of the second fold slot in the length direction and thatof the second end of the inner magnetic steel slot in the length direction form a second inclined angle; the first and second inclined angles are different. The first and second inclined angles are set to be different, thus optimizing the rotor structure magnetic path, increasing the rotor structure torque, reducing rotation pulse torque, improving the motor anti-demagnetism capability, and improving the motor efficiency.

Description

technical field [0001] The invention relates to the technical field of motor equipment, in particular to a rotor structure, a permanent magnet assisted synchronous reluctance motor and an electric vehicle. Background technique [0002] The torque output by the motor is not a constant value, but changes approximately sinusoidally as the rotor rotates in the stator. The ratio of the peak-to-peak value of the torque output waveform to the average value is called the torque ripple. The larger the torque ripple, the more unstable the output of the motor, and the greater the vibration and noise caused. Therefore, the size of the torque ripple is one of the important parameters to measure the quality of the motor. [0003] Permanent magnet reluctance motor is a new type of motor, because it can make full use of permanent magnet torque and reluctance torque, it has been widely used in modern production and life by more and more industries. For permanent magnet motors, the risk of ...
