- Abstract
As for ordinary transverse-flux permanent-magnet motors,there is a problem that the flux unipolarity cannot make further improvement on the output power or torque. To slove the problem,the transverse-flux permanent-magnet motor with bipolar flux was proposed. The motor employs outer rotor and its armature windings and permanent magnets are located in the stator. The flux path analysis show that the winding flux is bipolar. According to the basic structure,working principle and the design theory of motor,relationship between motor power and its size was deduced,and influence of main dimensions of motor on permanent magnet flux linkage was analyzed through finite element method. The size of a threephase 600 W prototype was determined,and its static and transient characteristics were simulated through finite element method including the magnetic field distribution and the back EMF at no load. For the correctness of the theoretical analysis,the experiment on the 600 W prototype was carried out and its results are in good agreement with the theoretical analysis.
