Abstract

This paper presents the study on stability speed BLDC motors in general by means of the voltage source inverter, the inverter is an IGBT full bridge. By taking the signal from the Hall sensors which mounted in the rotor to generate control signals for the inverter. The output of the inverter is connected to the stator windings of motor. Electromotive force of the motor is controlled via the control switching modes of inverter bridge. The motor speed is stable through the automatic voltage regulator power supply.
