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 permanent magnet slot set; the permanent magnet slot set comprises an outer permanent magnet slot; the rotor body is also provided with a first air slot; a first end of the first air slot and the end portionof the outer permanent magnet slot are connected or adjacent to each other; a second end of the first air slot extends to the outer edge of the rotor body and gradually gets away from the straight axle of the rotor body; when the first end of the first air slot is adjacent to the end portion of the outer permanent magnet slot, a first magnetic conductive channel is formed between the first end ofthe first air slot and the end portion of the outer permanent magnet slot. The rotor body is provided with the air slot that decides the direction of a rotor magnetic path, thus reducing magnetic flux leakage in a process in which the stator magnetic field reaches the rotor via an air gap, improving the magnetic field utilization rate, increasing torque output, minimizing demagnetization effect on the permanent magnet by a demagnetization magnetic field, and enhancing the anti-demagnetization capability.

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] Permanent magnet motors have the advantages of high efficiency and good mechanical properties, and are widely used in various fields of modern industry, but permanent magnets have inevitable demagnetization. Once demagnetized, it will lead to a decrease in the performance of the motor such as torque and efficiency. In severe cases, the motor may lose control and cause accidents. With the development of the times, permanent magnet motors tend to be miniaturized. Furthermore, the motors in the prior art still have the problem of low demagnetization resistance. Contents of the invention [0003] The main purpose of the present invention is to provide a rotor structure, a permanent magnet assisted synchronous reluctance motor and an electric v...
