Study of Modeling and Simulations of Permanent Magnet Synchronous Motor

Arun Kumar Yadav, Arvind Kumar, Anurag Dwivedi

Abstract


The modeling of permanent magnet synchronous motor field-oriented control is used for the operation
of the drive. The simulation includes all realistic components of the system. This enables the calculation
of currents and voltages in different parts of the inverter and motor under transient and steady
conditions. The losses in different parts are calculated, facilitating the design of the inverter. Closed
loop control system with a proportional integral (PI) controller in the speed loop has been designed to
operate in constant torque and flux-weakening regions. Implementation has been done in Simulink. A
comparative study of hysteresis and pulse width modulation (PWM) control schemes associated with
current controllers is made in terms of harmonic spectrum and total harmonic distortion. Simulation
results are given for two speeds of operation, one below rated and another above rated speed.
