Abstract


The transverse flux permanent magnet synchronous motor with a special magnetic circuit structure , easy- made ??multi-pole multiphase motor , suitable for applications in the field of low - speed large torque . This paper presents the structure of a two-way cross-linking transverse flux permanent magnet synchronous motor , the combined analysis by magnetic circuit analysis and finite element simulation method to improve the torque density of the motor as the goal , and analysis of the size of the motor parameters of motor revolutions the moment density summarized such motor design , developed an experimental prototype . The main research work include the following parts : First, put forward a two-way cross-linked structure of the transverse flux motor , so that the rotor permanent magnets are fully utilized , the stator core has a simple design, process , modular features . Analysis of the principle of operation of the motor through the magnetic circuit of analytical method to establish the three-dimensional magnetic circuit of the motor model, deduced the counter electromotive force of the motor unloaded equation, the torque equation , the establishment of a mathematical model of the motor , and analyzes the inductance parameters . Then, on the basis of the front magnetic path resolved to derive the formula of the main dimensions of the motor , and analyzed the relationship between the parameters and performance of electric machinery structure , in order to improve the torque density of the motor stator unit core size , winding size goals discussed , the size of the permanent magnet design . Finally, the establishment of a three-dimensional finite element analysis model of the motor , the motor distribution of the magnetic field strength , as well as no-load back-EMF motor output torque , positioning torque and leakage magnetic changes . According to the theoretical analysis and finite element simulation , design an experimental prototype for two-way cross-linking transverse flux motor structure , machining and assembly process of the main components of the motor . Its prototype experimental study to verify the feasibility of the design method and finite element simulation .
