FAULT TOLERANT CAPABILITY FOR BRUSHLESS DIRECT CURRENT (BLDC) MOTOR USING PIC MICROCONTROLLER

In this paper presents the parameter monitoring and speed control of Permanent Magnet Brushless DC Motor (PMBLDC) which is one of the best electrical drives that have increasing popularity, high efficiency, reliability, good dynamic response and it has very less maintenance. Brushless DC motors become popular in every application from home appliances to aerospace industry. The PIC controller is used for speed control of BLDC motor along with fault tolerant. The drive system fed from the PWM based Bridge Inverter, which gate pulses to be controlled by duty cycle ratio. The complete mathematical model of the drive system is developed and simulated using MATLAB software
