BLDC MOTOR SPEED CONTROL WITH RPM DISPLAY
ABSTRACT
The main objective of this project is controlling speed of BLDC motor and displays its
speed using an IR method of speed sensor mechanism. The DC motor has various application
used in industries like in drilling, lathes, spinning, elevators and 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 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 input
stage consists of entering the required speed through switches. The processing stage provides
RPM reference of the motor, by a shaft mounted IR sensor interfaced to the microcontroller in
the circuit. 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 being driven by the microcontroller output. An AVR 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 a LCD
display. The above operation is carried out by using one opto-isolator and a MOSFET for
driving the BLDC motor. IR sensing is used for getting the speed reference to the
microcontroller.

1. What microcontroller using? And why?
Ans: We are using AURDINO , (ATMEGA family, AVR)
 Because “Arduino is an open-source
 Electronics prototyping platform based on flexible, easy-to-use hardware and software.
 It’s intended for artists, designers, hobbyists, and anyone interested in creating
interactive objects or environments.
 “Arduino can sense the environment by receiving input from a variety of sensors and
can affect its surroundings by controlling lights, motors, and other actuators.
