[Abstract]:Single-phase permanent magnet low-speed linear motor is a new type of motor. It can directly convert electrical energy into the mechanical energy of low-speed linear motion by the change of air-gap magnetic guided wave. It has a wide application prospect in engineering field. More and more researchers at home and abroad favor. Based on the previous theoretical research, this paper draws lessons from the design experience of axial excitation, low speed rotation and linear motor. The principle of single-phase permanent magnet low-speed linear motor, air-gap magnetic field distribution, electromagnetic design and finite element three-dimensional simulation analysis are systematically studied. This paper presents the basic model of single-phase permanent magnet low-speed linear motor and the split phase operation circuit, starting from the working principle and low-speed operating conditions of the motor. The axial excitation magnetic potential and the air gap magnetic field produced by AC windings and the distribution of axial magnetic flux in the air gap are deeply analyzed. Then the electromagnetic design of this kind of motor is carried out. At last, the prototype model is established according to the design parameters. Considering the particularity of the magnetic circuit of the motor, in order to get closer to the actual operation effect of the motor. In this paper, the static and dynamic characteristics of the prototype are simulated by using Magnet software. The simulation results show that the design of the prototype is correct and reasonable.
