摘要：
To realize the high performance magnetic suspension and drive control of three-phase bearingless induction motor, the problems of magnetic field orientation strategies for four-pole torque system and two-pole magnetic suspension system were studied in detail. Firstly, analyses and contrasts between air gap flux orientation and rotor flux orientation strategies of torque system were made. Then, the flux orientation strategy of magnetic suspension system was analyzed, and the induction compensation method for none pole-specific rotor circuits of magnetic suspension system was given. At the end, according to the operation characteristics of three-phase bearingless induction motor, rotor flux orientation strategy for torque system, air gap flux orientation strategy and induction compensation for magnetic suspension system were adopted, and simulation and experimental studies on the decouple control system of three-phase bearingless induction motor were made. Simulation and experimental results show that stable and reliable magnetic suspension control and higher decoupling performances can be achieved. The presented flux orientation strategies are feasible.
