【摘要】 横向磁通电机以其高转矩密度的优势而得到了发展,但结构复杂也限制了其应用场合。文中采用轴向充磁的永磁体,实现了一种结构相对简单的新型横向磁通永磁电机。为解决电机磁场建模、分析复杂等问题,引入隔磁磁障实现了三维场到二维场的简化。为实现优化设计,对电机关键参数和尺寸进行了合理选取,最后给出了样机电磁方案。分析结果表明,这种新型永磁电机的制造工艺相对简单,适合中小功率低速直接驱动要求。更多还原

【Abstract】 Transverse-flux permanent magnet machine (TFPMM) is developed for its merit of high torque density, but its complex structure has limited its applications. The axial charge magnetism’s permanent magnet is used to construct a novel TFPMM with a simplified structure. Due to the complexity of modelling and analysing, a flux barrier is introduced to simplify 3D magnetic field to 2D. Besides, optimizations on machine structure, size and some critical parameters have been given, and a prototype scheme is presented in the end. Results show that this novel TFPMM producing technics is relatively and it meets the requirements of direct driving in low power occasion.更多还原
