In order to promote the development of green energy applications, this paper selects a 4-pole 24-slot surface-mounted permanent magnet synchronous motor and performs finite element simulation optimization design on it. Firstly, analysis is carried out, performance verified by simulation. Then, parameterized sensitivity cogging torque three-phase current are performed selecting variables thickne...

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...
