摘要
横向磁通永磁电机具有电及磁负荷解耦、功率密度转矩密度高的优点,极适合低速直驱场合。本文基于小型风力发电提出一种新型盘式横向磁通永磁发电机,由于采用了软磁复合材料与叠片硅钢材料组合定子铁心盘式结构,电机在具有横向磁通电机优良性能的基础上,还具有低的轴向长度和很低的漏磁和较高的运行效率。本文首先介绍了该电机的结构和原理,并给出了尺寸方程的推导公式,基于此,利用三维电磁场有限元方法分析了该电机空载状态下的气隙磁密、磁链、空载反电势波形及负载输出转矩波形。最后,根据理论计算,设计研制了一台盘式横向磁通永磁发电机样机,并进行了初步试验,进一步验证了电机性能的优越性。
Transverse flux permanent magnet motor has the advantages of decoupling electrical and magnetic loads,high power density and torque density,which is very suitable for low-speed direct drive applications.In this paper,a new type of disk type transverse flux permanent magnet generator based on small wind power generation was proposed.Due to the stator core disk structure composed of soft magnetic composite material and laminated silicon steel material,the generator has low axial length,low magnetic leakage and high operation efficiency.First,this paper introduced the structure and principle of the motor,and gave the derivation formula of the dimension equation.Based on this,the air gap flux density,flux linkage,no-load back voltage waveforms and and load output torque waveform of the generator under no-load state were analyzed by using finite element method.Finally,according to the theoretical calculation,a prototype of disc-type transverse flux permanent magnet generator was designed,and the preliminary test was carried out,which further verified the superiority of the motor performance.
