异步起动游标永磁电机研究

Compared to the normal line start permanent magnet machines (LSPMM), the line start permanent magnet vernier machine(LSPMVM) are to be with higher torque density and efficiency, which indicates significant socioeconomic benefits once it is widely used. we mainly focus on researches on the the key technology questions of LSMVM by the methods including fundamental theoretical analysis, simulations and experimental researches. Our main work includes four aspects as follows: a) analysis the harmonic characteristics of LSPMVM under different operating conditions to find the basic theories of LSPMVM; b) establish the dynamic analysis and simulation modelsconsidering strong interaction effect; c) research on the design methods of general topology, rotor type, stator winding and starting winding; d) propose a new topology of LSPMVM with both excellent starting and steady-state operation capabilities,which is hard to achieve because of the strong interaction effect. Based on above works, we can finally get a better analysis theory and design method of LSPMVM and those works will provide useful theoretical support for the development and application of LSPMVM.
