Description

New energy automobile motor with magnetic suspension Technical Field The invention relates to the technical field of automobile motors, in particular to a new energy automobile motor with a magnetic suspension. Background With the rapid development of the new energy automobile industry, the performance requirement on a driving motor, which is a core component of the new energy automobile, is increasingly improved. During the operation of the motor, particularly during start-stop, acceleration and deceleration and load changes, significant vibration and noise can be generated. These vibrations, if transmitted directly to the vehicle body, can severely impact the NVH (noise, vibration and harshness) performance of the vehicle, reduce ride comfort, and can affect the fatigue life of the motor and its connected components. At present, the traditional motor suspension of the new energy automobile mostly adopts rubber suspension or hydraulic suspension. The rubber suspension has a simple structure and low cost, but the rigidity and damping characteristics of the rubber suspension are fixed, the rubber suspension cannot adapt to the requirements of the motor on the rigidity and damping change of the suspension system under different working conditions (such as no-load and full-load, stable running and violent acceleration), and the contradiction between the low-frequency vibration isolation effect and the high-frequency dynamic rigidity control exists. Although the hydraulic suspension improves the frequency-dependent characteristic to a certain extent, the hydraulic suspension has the problems of complex structure, high cost, liquid leakage, poor low temperature resistance, performance attenuation after long-term use and the like. To solve the above problems, magnetic levitation (magnetic vibration isolation) technology is introduced as an emerging solution. The principle that magnets repel each other in the same poles is utilized to provide non-contact supporting force, and the non-contact type magnetic iron has the advantages of being free of friction, long in service life, active and controllable in theory. However, the existing magnetic suspension schemes still have obvious limitations that the relative positions and the magnetic field directions of the magnets in most designs are fixed, so that the magnitude and the direction of the repulsive force generated by the magnets are not adjustable. Once installed, its suspension stiffness (i.e., force-displacement characteristics) cannot be changed. This makes it difficult for a single magnetic levitation suspension to adapt to complex operating conditions of the electric machine. For example, a high stiffness suspension designed to ensure support during full load would appear too "hard" when empty, resulting in reduced vibration isolation, whereas a soft suspension designed for comfort would not be able to effectively inhibit displacement of the motor during high torque output, affecting the stability of the drive train. In addition, even if some adjustable magnetic suspension structures exist, the adjusting mechanism is often complicated, and parts are required to be disassembled or special tools are required to be used, so that the quick and accurate debugging in the whole vehicle assembly line or after-sale maintenance is inconvenient, and the application of the magnetic suspension structures in practical engineering is limited.
