Vector Control of Sensorless BLDC Motor

BLDC motor is widely used in industrial drive applications due to high efficiency, high power and easy maintenance. However position and speed sensors generally used in BLDC motor increase drive cost, and reduce application range. This study describes sensorless speed control using instantaneous voltage-current equation, and presents the results of computer simulation.
