In today's time, to work in all fields, we need a motor with low power consumption and efficient work that is why BLDC motor is very famous in the new trend. Therefore it is important to understand the control techniques and have been explored electronic commutation method of BLDC motors. In this, the combination of traditional method and new method using hybrid commutation is understood. The traditional method is Zero Cross Detection Back EMF method and the innovative method is based on PID controller plus CPLD control technique. This paper shows the tabulation of torque and various features of PID plus CPLD control technique. Using these techniques together greatly improves the performance of the BLDC motor, discussed in this research work.
