摘要
以1台4/2极结构高速开关磁阻电机(SRM)为研究对象,研究纳米晶铁心磁特性及其对电机性能的影响。将采用叠块切割法制备的纳米晶定子铁心与传统硅钢冲片铁心做对比测试。搭建电机测试系统,对分别装配两种定子铁心电机的静态特性和负载运行性能做对比分析。结果表明:纳米晶合金铁心具有高磁导率、低矫顽力及低损耗特性,在1 kHz、1 T条件下,其损耗仅为35W300硅钢铁心的1/20;纳米晶合金铁心提高了SRM在铁心不饱和区的相电感峰值,并在转速25 000 r/min负载运行下显著降低了电机温升和输入功率。研究结果可为高效、高速SRM设计提供参考。
With a 4/2 geometry high-speed switched reluctance motor(SRM), the magnetic properties of nanocrystalline stator core and their effects on the motor were analyzed. First, the stator core fabricated by wire-electrode cutting was tested and compared with the silicon steel core. Then, the motors were tested in static and running in load modes. Results indicated that the nanocrystalline core had higher magnetic permeability, smaller coercivity and lower core loss, with only 1/20 of 35 W300 silicon steel core loss under the excitation conditions of 1 kHz and 1 T. The motor with nanocrystalline stator core had higher phase inductance, in comparison with the silicon steel core motor, and both core loss and input power of which were reduced at a speed of 25 000 r/min and the same output power. Results could be used for the optimization and performance improvement of high speed SRM.
