Design, Code Generation and Simulation of a BLDC Motor Controller usuuing PIC Microcontroller

Brushless Direct Current (BLDC) motor are one of the electrical drives that are continually gaining popularity in motion control applications due to their high efficiency, good dynamic response and low maintenance. Unlike DC motors and Induction motors, BLDC motors needs a controller as the motor runs in 3 phases but takes DC input. The controller converts DC power to 3 phase AC power suitable for the motor. This paper propose a design, code generation method and digital logic control of a BLDC motor controller for turning the rotor clockwise or counter clockwise. A Pulse Width Modulation (PWM) speed control strategy is performed to adjust the rotor speed. The framework is modelled and simulated by using Proteus software.
