INTRODUCTION
 The presentation is meant to control the speed of a
BLDC motor using closed loop control technique.BLDC
motor has various applications used in industries like in
drilling, lathes, spinning,electric bikes etc. The speed
control of the DC motors is very essential. This proposed
system provides a very precise and effective speed
control system. The user can enter the desired speed
and the motor will run at that exact speed
