With the deepening of the global energy crisis,wind power generation,solar photovoltaic power generation,wave power generation,solar thermal power generation and other clean and renewable energy power generation have become research hotspots.The main content of this paper is a kind of transverse flux permanent magnet linear generator which is matched with the power generation system.Transverse flux permanent magnet linear motor is different from traditional motor in magnetic circuit structure.Armature winding and stator slot are perpendicular to each other in space,thus decoupling electric load and magnetic load is realized.Transverse flux permanent magnet linear motor not only inherits many advantages of permanent magnet motor,but also has the characteristics of transverse flux and linear drive.Therefore,transverse flux linear motors have broad application prospects in the fields of low speed and high thrust.In this paper,the transverse flux permanent magnet linear generator is taken as the research object,and its theoretical analysis and calculation are carried out.The main research contents are as follows:1.The research and development status of transverse flux permanent magnet linear motor at home and abroad are analyzed and investigated to provide theoretical basis for the research of transverse flux permanent magnet linear motor.2.The finite element simulation model of transverse flux permanent magnet linear generator is studied.Based on this model,the influence of various parameters on the motor is studied and optimized by analytical calculation,and the load characteristics of transverse flux permanent magnet linear motor are simulated and calculated.3.The equivalent circuit of transverse flux permanent magnet linear generator and its mathematical model are analyzed,and the simulation model of transverse flux permanent magnet linear generator is built in MATLAB/SIMULINK through the mathematical model,and the feasibility of transverse flux permanent magnet linear generator is verified through simulation.4.By comparing the results of finite element simulation and MATLAB/SIMULINK,the accuracy is analyzed,and the differences and deficiencies between the two are analyzed,which lays a foundation for the final motor experiment.5.Set up an experimental platform for transverse flux permanent magnet linear generator.Based on the simulation verification results of lumped parameters,the experimental data are verified.The rotating motor is used to replace the linear motor.The analysis of the experimental results provides an analytical basis for the research of transverse flux permanent magnet linear generator.
