【Abstract】 The structure and principle of synchronous reluctance motors( SynRM) were briefly introduced. The relationship between main parameters of rotor such as number of barrier layers,the percent of barriers,the width of rib,and machine’s induction and saliency ratio was investigated using finite-element software. These works would provide reference for the design of SynRM. The SynRM’s characteristic of inductance and torque under different current load were also investigated,the simulation results indicated that the inductance and the current angle of Maximum Torque Per Ampere( MTPA) was influenced by current load. Finally,the prototype was made according to the result of simulation and the simulation results were proved to be correct by the experiments.更多还原
