- 摘要:
- 相较于表贴式电机,磁阻转矩是内置式永磁电机所特有的。磁阻转矩的分析对内置式永磁电机尤为重要。本文提出了一种精确的内置式永磁电机的模型,该模型基于冻结磁导率法可以实现内置式永磁电机的各个转矩分量的分离。同时还发现由于转子磁场与定子铁心中的不等d和q轴磁阻的相互作用,会产生附加的转矩分量。本文所提出的模型可以在任何负载条件下再现瞬时转矩波形,与传统方法相比,提供了更精确的磁阻转矩评估方法
- Abstract:
- Compared to surface-mounted permanent magnet machines, reluctance torque is unique to interior permanent magnet machines. Analysis of reluctance torque is especially important for interior permanent magnet machines. This paper proposed an accurate model which allows for separation of torque components based on frozen permeability concept for interior permanent magnet machines. An additional torque component due to the interaction of the rotor magnetic field with unequal d and q-axis reluctances in the stator iron was included. The proposed model can reproduce the instantaneous torque waveform at any load condition, and hence provides a more accurate means of reluctance torque evaluation compared with the conventional methods
