摘要
为了解决传统12极36槽的汽车永磁发电机电动势谐波含量大、绕组叠落难以提高槽满率、齿槽转矩大等问题,提出一种16极18槽分数槽绕组汽车永磁发电机。在给出分数槽集中绕组汽车发电机优点和永磁发电机的损耗模型的基础上,对比分析两种发电机的拓扑、感应电动势和关键部位的磁感应强度,并利用波托蒂铁心损耗模型计算了两种发电机的损耗。仿真结果和实验表明,16极18槽汽车永磁发电机具有更高的效率、更低的齿槽转矩和电动势谐波。
In order to solve the problem of high EMF harmonics, low slot full rate, and large cogging torque of the traditional automobile PM generator with 12-pole and 36-slot, a fractional slot automobile PM generator with 16-pole and 18-plot will be proposed. With the given advantages of the automobile generator with fractional slot concentrated windings and its loss model, the topology of the above two automobile generators will be compared. The EMF aud flux density of several important different places will be give, which will be used to calculate the iron loss with Bertotti＇s iron loss theory. The simulation and experiment result show that the 16-pole and 18-plot automobile PM generator has the character of high effwieney, low cogging torque and EMF harmonic.
