PMSM Mathematical Model Comparison with Simulink Model

Presence of permanent magnets in its rotor assembly the power density of permanent magnet synchronous motor is higher than one of induction motor with the same ratings due to no stator power is dedicated to the magnetic field production. PMSM has more advantages like compact form with high torque density and less weight, higher continuous torque over a wider range of speeds, lower rotor inertia, higher dynamic performance under load, higher operational efficiencies with no magnetizing current, and the corresponding absence of heat due to current in the rotor, low torque ripple effect, more robust performance compared to dc motors, because of these advantages Permanent magnet synchronous motors are increasing applied in several areas such as traction, automobiles, robotics and aerospace technology. In this paper mathematical modelling of PMSM is done and simulation results compared with MATLAB SIMULINK model.
