For the calculationof torque in synchronousmotors a local method is analysed, based on the Maxwell stress theory and the filtered contributions due to the harmonics of the magnetic vector potential in the motor air-gap. By considering the space fundamental field only, the method can efficiently estimate the average synchronous torque for a variety ormotor topologies, including concentratedwindi...

Abstract Nowadays, before the era of modern Steer-by-wire steering systems, most widely used technology is Electric Power Steering (EPS). This paper contains developing a Permanent Magnet Synchronous Motor (PMSM) control circuit for EPS in Matlab Simulink environment. The mathematical model was created via four equations that represent relation between fluxes, voltages and currents d-q referenc...

This paper investigates the design of a robust linear parameter-varying (LPV) controller for speed regulation surface permanent magnet synchronous motors (SPMSMs). Motor dynamics is defined in t...
