WebJan 26, 2024 · The synchronous velocity of the moving magnetic field in an induction motor can be calculated by { N }_{ s }=\frac { 120f }{ P } (RPM) where f is the frequency of the system and P is the number of poles in the stator. The synchronous velocity varies with the change in the frequency of the system. WebThus, the advantage of the combined method for the low-speed area against resistance variation is kept. Various hardware-in-the-loop experimental studies and comparative analysis show that the proposed method with a permanent flux linkage variation back EMF compensator achieved an excellent sensorless control performance for IPMSM.
