提出了一种基于多路三相电压源逆变器的九相永磁同步电机驱动系统。研制了一种用于超高速电梯牵引电机的九相永磁同步电动机。通过系统的对称性，简化了电机的数学模型。利用该简化模型，驱动系统可以采用著名的d-q控制理论进行控制。在世界上最高的电梯试验塔上，实验验证了该驱动系统的可行性和有效性。此外，为了保证系统的容错能力，还进行了额外的实验。
This paper presents a nine-phase permanent-magnet synchronous motor (PMSM) drive system based on multiple three-phase voltage source inverters. The nine-phase PMSM was developed as a traction motor for an ultrahigh-speed elevator. The mathematical model of the motor was simplified through symmetry of the system. Using the simplified model, the drive system can be controlled by the well-known d-q control theory. The feasibility and validity of the drive system were experimentally demonstrated at the world's tallest elevator test tower. Moreover, an additional experiment was performed to ensure the fault-tolerance capability of the system.
