Magnetostrictive behavior of the electrical steel cores of transformers and electrical machines has been studied under well-known excitation waveforms, e.g., purely sinusoidal. However, the magnetization may contain higher harmonics due to the grid harmonics for the application in transformers or due to pulse width modulation excitation in the case of induction machines. We have reported the presence...
Sensorless control of permanent magnet synchronous machines (PMSM) is often carried out by evaluating current ripples resulting from the supply of high-frequency voltage test pulses. Simulations of a sensorless drive are usually based on a state-space model with constant q and d inductances and no mutual inductances. In this paper, this technique is improved by calculating the inductance matrix from...
