ABSTRACT

The main subject of this paper is to optimize the design of permanent magnet linear oscillating motor . This paper can be divided into five chapters. Background and Significance problem starting the first chapter to start, and then describes the research status quo and development trend of the linear oscillating motor. Finally details the purpose and content of this paper. The second chapter introduces the basics of linear motor, from the traditional squirrel-cage rotary motor to the linear motor and then to the linear oscillating motor. The third chapter describes in detail the modeling of permanent magnet linear oscillating motor studied in this paper, setting parameters, simulation and analysis of simulation results, the basis for the optimization design behind it. The fourth chapter describes the optimization of the permanent magnet linear oscillating motor, mainly from changes in the parameters of the motor 4 to discuss. The fifth chapter is the last references and acknowledgments. The main focus of this paper is the third chapter of simulation design and the optimization design of chapter fourth.

In the simulation design, respectively, when the motor load positioning force, the three-EMF mover movement position, velocity, electrical magnetic field lines and magnetic flux density distribution to inspect, focusing on positioning force and three potential two opposite amount. And then by the three-EMF no-load current draw should be added to the initial phase excitation, and finally get current excitation expression statements, by controlling the current to control the permanent magnet linear oscillating motor sport.

In the optimized design, based on the positioning of the force and the thrust of permanent magnet linear curve oscillation motor idling and join current excitation, combined with related linear oscillating motor optimization design knowledge, respectively, gap width, the size of the current amplitude, coils the number and quality of the mover of the four factors that affect motor performance to be investigated. Finally, get some optimization design ideas.

Keywords：Permanent magnet linear oscillating motor, Ansoft Maxwell FEM, Linear motor design, Linear motor Optimization
