The aimed objective of this Research project is to control the speed and direction of brushless DC (Direct Current) motor, through RF (Radio Frequency) module. Microcontroller is the central part of this project which is controlling all the process i.e. checking for over current, under/over voltage and starting the auxiliary motor (for load sharing) in case of overloading etc. If the motor is having under or over voltage problems then it will automatically be stopped, to protect it from any damages. The process of speed control will be done by PWM (Pulse Width Modulation) technique. & lastly an advantage feature kept is the direction control of this motor.

Excerpt from the Book
Physical Modelling & Hardware Implementation Process
Before implementing the hardware, block diagram should be made to identify the path on which work will be continued. As shown in the above figure that microcontroller is the central part of the project which is used to receive the information about the speed and direction through RF receiver. Microcontroller controls the direction of motors through relays, where speed will be controlled through the PWM process. For load sharing process a comparator is connected with controller, which continuously measure the drop across the motor, in case the drop goes high it will turn on the second motor through relay, this motor will work parallel to the first motor, this make the load sharing between the two motors, which protect the motor from any damages. The under and over voltage protection is also available by using under and over voltage protection kit. This kit turns off the motor when it observe the abnormal behaviors.
