摘要
提出了一种新型聚磁型无源转子横向磁通永磁电机。首先分析了该电机的基本结构和运行原理,借鉴永磁同步电机的成熟理论方程推导了该电机的电磁设计公式,并给出了相应的优化流程图。采用三维有限元方法分析了电机的磁场分布,给出了空载反电势、相电感及其齿槽转矩波形。该电机的气隙磁密比传统横向磁通永磁电机高,采用聚磁型结构提高了永磁体的利用率。漏磁严重使得横向磁通永磁电机的相绕组自感比较大,通过仿真分析了电枢反应对电机的影响。
A novel flux-concentrating transverse flux PM machine with passive rotor was proposed. Firstly, the basic structure and operation principle of the machine was analyzed. The electromagnetic formulae of the ma- chine was derived according to the mature theory formula of the permanent magnet synchronous motor, and the optimization flow chart was given. The phase no-load EMF, no-load inductance and cogging torque waveform were studied by 3-D FEM analysis. The air gap flux density of the machine is larger than traditional transverse flux PM machine, and improving the utilization rate of the permanent magnet with the flux-concentrating struc- ture. The serious magnetic flux leakage of the transverse flux PM machine makes phase winding inductance larger, and the influence of armature reaction on the machine was analyzed through the simulation.
