Research on Control Strategy of Axially-laminated Anisotropic Rotor Reluctance Synchronous Machine

为达到轴向叠片转子磁阻同步电机调速范围宽的目的,从相量图出发,通过对ALA转子磁阻同步电机的失量控制策略进行分析和实验验证,获得了最大电磁转矩、最高功率因数、最高转速同电流综合矢量超前d轴角度的关系,设计了以TMS320F2812 DSP处理芯片为核心的矢量控制平台,实验得到了2.8倍的调速范围。结果表明,矢量控制策略实现了电机快速响应、高效节能且调速范围宽的效果。

In order to obtain a wide speed range of axial laminated rotor reluctance synchronous motor, the re- lationship among the maximum electromagnetic torque, the maximum power factor, the maximum speed and the current synthetic vector leading d axis angle was obtained based on the phasor diagram through the vector con- trol strategy and experiments of ALA rotor reluctance synchronous motor. A vector control platform with TMS320F2812 DSP processing chip as the core was designed, and the 2.8 times speed regulation range was obtained in the experi- ment. The experimental results showed that the vector control strategy had realized the effect of electrical motor＇s fast response, energy- efficient and wide speed regulation range.
