Variable Speed BLDC Motor Drive Using PIC Microcontroller
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 1
Abstract
This paper aims to design and implementation of BLDC motor speed control based on the POT variation. This project is mainly concerned on BLDC motor speed control system by using microcontroller PIC 16F877A. Motor speed can be controlled with variable POT, based on which the PWM pulse is generated. So, this programming device can be used to control any motor and their speed. The POT is used to give the speed range to the controller. The heart of the circuit is the POT and microcontroller which controls all its function. The PIC microcontroller has 10bit resolution ADC, which is used to convert the POT’s analog signal into digital. The speed variation can be in large range (i.e, 1024 different speeds). A hall sensor is used for the feedback from the BLDC motor to measure the rotor position. Based on the rotor position the MOSFET switches in the VSI will be switched with the PWM pulse from the controller. The VSI has 6 MOSFET switches. The speed of the motor is displayed on an LCD. In this project, PIC 16F877A microcontroller can control motor speed at desired range with variable POT and rotor position.
