Abstract
The Permanent Magnet Brushless DC motor (PMBLDC) has a permanentmagnet rotor, and the stator windings are wound such that the back electromotive force (BEMF) is trapezoidal. Therefore it requires rectangular shaped stator phase currents to produce constant torque. The trapezoidal back EMF implies that the mutual inductance between the stator and rotor is nonsinusoidal.
The objective of this project is to develop a simulation of PMBLDC using Matlab / Simulink software. The result of this simulation is to show theperformance of the PMBLDC by referring its stator current, speed, torque and back electromotive force (BEMF). This result will be compare with the ideal waveform obtained from theory. In this simulation model, the PMBLDC is controlled by hysteresis current controller and PI controller for motor speed.
