[Abstract]:With the continuous rapid development of the national economy and the continuous improvement of people's quality of life, people not only improve the size of the internal space and environmental considerations, but also have higher and higher requirements for the vehicle's tire runout and body vibration. Because it's about the ride comfort of the driver and the ride comfort of the car. The stability and reliability of suspension system are very important. Compared with other motors, cylinder linear motor has the advantages of simple structure, high efficiency, good stability and fast response speed. Therefore, cylinder linear motor has a good prospect in the field of suspension system. In this paper, two kinds of fault-tolerant permanent magnet cylinder linear motors are analyzed and designed. The simulation model of the two motors in Maxwell software is constructed; the optimal size of the motor is determined; the static characteristics of the two motors are analyzed; the parameters of the motor are optimized and a prototype is made. The fabrication process of the prototype is described in detail, and the experimental results show that the proposed permanent magnet cylinder linear motor has better characteristics than the ordinary cylinder motor. In order to solve the problem of poor fault-tolerant performance, a new type of permanent magnet linear motor with fault tolerance is proposed, which has the following four aspects: 1) according to the current research situation of cylinder linear motor, a new type of permanent magnet linear motor with fault tolerance is proposed. The working principle is described in detail, the parametric analysis model of the five-phase cylinder motor in Maxwell simulation software is set up, and the static characteristics of the surface-mounted cylinder linear motor are analyzed by using finite element method to calculate and optimize it. This paper presents a new type of permanent magnet embedded cylinder linear motor, and establishes the Maxwell parametric simulation analysis model of the motor, including the distribution of magnetic force line, no-load backEMF, positioning force, thrust and inductance, etc. The static characteristics are analyzed, including magnetic force line, inductance, no-load backEMF and harmonic, positioning force and fault-tolerant ability, and the relative static characteristics of the two kinds of cylinder motor are compared and analyzed. According to the structure and parameters of the proposed motor and the machining characteristics of the cylinder linear motor, the machining details of the proposed prototype are described in detail, including primary, secondary, and so on. Coil .4) the mathematical models of the motor in two different coordinate systems are studied, the control strategy used in the experimental control of the prototype is described, and the experimental test of the machined motor is carried out.
