This paper exhibits a speed control technique for brushless dc motor (BLDC) drives by estimating speed using the hall sensor signals. Conventionally, the speed is measured using precision speed encoders. As these encoders cost is high and almost half of the entire drive system. As the sensorless method has algorithm complexity and catastrophic, there arises need of cost effective speed estimation technique. This is proposed by measuring the speed and position from hall sensors. Here a closed loop speed controller is proposed using PID controller and current controlled pulse width modulation (PWM) technique since BLDC motor is electronically commutated machine, the commutation period is determined by switching table that shows hall signal status. The entire system is simulated in MATLAB/simulink and the performance of the system is analyzed for different speed and references
