Abstract : This paper discusses the causes of oscillation in ALA rotor motors under VVVF inverter power supply starting, pointing out that the oscillation is due to the low electromagnetic damping coefficient of the motor. By using a stepper motor to eliminate low-frequency oscillations and adding a mechanical inertial damper to the rotor, the anti-interference capability of the system is improved, and the variable frequency starting performance of the motor is significantly improved. Simultaneously, load performance experiments also prove that the inertial damper can significantly improve the load capacity of the motor.

The stator of this motor is similar to that of a conventional AC motor, while the rotor is composed of laminations of high-permeability materials and non-magnetic insulating materials, alternately and densely stacked along the axial direction, as shown in Figure 1. Its magnetic permeability exhibits high anisotropy, and the salient pole ratio Ld/Lg can reach 10-20 times that of Jintong motors. The motor thus possesses advantages such as high torque density, fast dynamic response, low torque ripple, and low loss, making it a promising candidate for high-quality AC variable speed drives. In prototype experiments, we found that two-pole ALA rotor motors may exhibit oscillation and asynchronous operation when started with inverter power. Specifically, when the power supply frequency exceeds a certain critical value, the motor loses synchronization and oscillates around half the synchronous speed. In the inverter starting experiment of a four-pole ALA rotor motor, the motor's operation improved somewhat due to the decrease in the salient pole ratio, but the oscillation and loss-of-synchronization problems persisted. To further advance this new type of motor towards practical application, the starting problem under inverter power supply must be solved. Therefore, this paper presents a comprehensive experimental study on the inverter starting performance of the prototype.
