Abstract

The BLDC motor is an electronically commutated dc motor becoming very popular in many applications. There are various speed control methods used for BLDC motor. The performance of BLDC motor drives can be improved using sensored control t echniques over sensorless technology. This paper presents Brushless Direct Current motor drive system and its sensored speed control technique with PWM. Advantages and limitations of sensorless techniques are reviewed and then, sensored speed control tech nique is introduced with their advantages, performance analysis, practical implementation and applications. Torque and speed behavior during clockwise and anticlockwise motion, use of hall sensors to detect rotor position, speed control technique using PWM method are discussed in detail. Detailed hardware design its implementation and experimental results covered. This paper also covers performance analysis of BLDC motor using experimental results.
