Detailed Analysis of Torque Ripple in High Frequency Signal Injection based Sensor less PMSM Drives
Abstract:
High Frequency Signal Injection based techniques are robust and well proven to estimate the rotor position from stand still to low speed. However, Injected high frequency signal introduces, high frequency harmonics in the motor phase currents and results in significant Output Torque ripple. There is no detailed analysis exist in the literature, to study the…
