Abstract

In this paper, a novel flux-weakening control method for Interior Permanent Magnet Synchronous Motors (IPMSMs) has been proposed. The proposed flux-weakening control method is discussed on the Maximum Torque Control (MTC) frame, which is possible to realize simple and robust sensorless control system. First, the proposed flux model for position sensorless control of IPMSMs has been reviewed, in which this model can approximately estimate the MTC frame, which stands for a new coordinate aligned with the current vector at the the Maximum Torque Per Ampere (MTPA) control. Next, a new flux-weakening method suitable for this flux model has been proposed. Finally, some experimental results demonstrate the effectiveness of the proposed method.
