This paper intends to develop a three phase Y-connected Brushless DC (BLDC) motor controller by using low cost PIC 18f4431 microcontroller. Unlike a brushed DC motor, the commutation of a BLDC motor is controlled electronically. To rotate the BLDC motor, the stator windings should be energized in a sequence so it is important to know the rotor position in order to understand which winding will be...
