ABSTRACT:
The main objective of this project is controlling the speed of BLDC motor and displays its speed using an IR method of speed sensor mechanism. 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 increase or decrease the speed as per the requirement and the motor will run at that exact speed.The project is divided into three stages: input, processing and output stage. The microcontroller develops PWM pulses which are varied with switches to regulate the DC power to the motor such that the desired speed is achieved. The output stage uses a MOSFET is driven by the microcontroller output. An 8051 family microcontroller is used with a set of switches to increase or decrease the speed of the BLDC motor. This speed is sensed by the sensors and is given to microcontroller which in turn displays it on an LCD display. The above operation is carried out by using one optoisolator and a MOSFET for driving the BLDC motor. IR sensing is used for getting the speed reference to the microcontroller.
