Speed Control of Sensorless BLDC Motor

N. Kalpana

Abstract


This paper is designed to control the speed of a Sensorless BLDC motor using PIC micro controller. Through sensorless technology the reliability &performance of BLDC motor drivers have been improved as the conventional control and sensing techniques have been improved. BLDC motor has widely application used in industries like in drilling, lathes, spinning, electric bikes etc. it is very essential to control the speed of BLDC motor. This paper provides a very accurate and effective speed control system. The person can enter the desired speed and the motor will run at that exact speed.

 

Keywords: Brushless DC (BLDC) motor, electro motive force (EMF), permanent magnet (PM), synchronous motors (PMSM), PIC microcontroller
