Abstract

Synchronous motors are the most commonly used steady-state three-phase AC motors in electrical systems. The synchronous speed of these motors remains constant, being equal to the supply frequency and its rotational period corresponding to the integral number of AC cycles. So, these motors are mainly used to improve the power factor in power systems.

The paper focuses on field-oriented control of a permanent magnet synchronous motor to effectively control its speed and torque. AC motors only have stator currents, so separate control mechanisms such as vector controls are required to control the motor’s operation. Field-oriented control is the most commonly used vector control, which helps to control motor flux and torque independently, thereby controlling the motor speed.[1]

Simulation and hardware implementation of field-oriented control using Space Vector Pulse Width Modulation (SVPWM) is discussed in this paper. The system is modelled in MATLAB SIMULINK.
