The aim of this study was to develop a new method to operate an interior permanent magnet synchronous machine (IPMSM) on the maximum torque per ampere (MTPA) condition. The characteristics of the MTPA condition were analyzed and the MTPA condition was derived based on the input electric power. The proposed method injects a small current signal used for tracking the MTPA operating point along with...
This paper presents a new maximum torque per ampere (MTPA) control method for Interior Permanent Magnet Synchronous Machine (IPMSM) drives. The proposed method uses the conventional speed control scheme, where speed control loop produces the magnitude of the stator current reference. According to the current angle in the rotor reference frame, ??, the current reference is decomposed to the d-/q-axis...
