Abstract
A study on position and speed is made on BLDC (Brushless DC motor) in this research. The study is performed based on the sensor less technology which includes background investigation. Compared to the conventional method, the reliability and the performance of BLDC motor is improved using the proposed design. In the simulation, controlling the speed of BLDC motor is performed. In simulation, the speed of the BLDC motor remains constant even when the voltage varies. Further in the real time experimentation sensor less are studied in terms of merits and demerits, further an analysis is made on design parameter, issue in implementation and the application. The study includes an Electro Motive Force sensing methods, Terminal Voltage Sensing and Terminal Current Sensing. Using microcontroller (Atmega8A) board and Electronic Speed Controller, the speed of the motor is controlled by varying the 10k potentiometer. The parameter like speed and rpm are obtained and shown in the load display.
