摘要
针对传统磁悬浮开关磁阻电机转矩与悬浮力的控制耦合问题,提出一种采用混合转子齿的新型16相磁悬浮开关磁阻电机。将转子齿划分为转矩齿和悬浮力齿,并增大悬浮力齿的极弧,消除了悬浮力调节对转矩的影响,分块转子结构和短磁路励磁消除了不同绕组间的磁力线耦合。在Ansys Maxwell 2D中建立样机模型进行磁链仿真,结果表明,该结构实现了转矩与悬浮力的解耦控制。求解了电机转矩和悬浮力的数学模型,通过有限元仿真软件验证了数学模型的正确性,为该电机悬浮力和转矩控制提供了依据。
Aiming at the control problem of coupling between torque and suspension force of traditional bearingless switched reluctance motor (BSRM), a new 16-phase BSRM with hybrid rotor teeth was proposed. The rotor teeth were divided into torque rotor teeth and suspension rotor teeth, and the pole arc of the suspension rotor teeth was increased to eliminate the influence of suspension regulation on torque. The coupling of magnetic induction lines between different windings was eliminated by the segmental rotor and short magnetic path. The prototype model was built in Ansys Maxwell 2D for flux linkage simulation, and the results show that the new structure has an ideal decoupling effect. The mathematical model of torque and suspension force was established, and the correctness of the mathematical model is verified by finite element software, which will provide a basis for the motor suspension force and torque control.
