This paper presents a significant improvement in sensorless control technique for a PMBLDC motor drive to enable the drive to work satisfactorily over a wide range of speed. The filters used in conventional techniques for filtering the back EMF obtained from the motor are designed for a particular speed having a particular value of time constant. Adaptive(More)
This paper presents a significant improvement in sensorless control technique of PMBLDC motor drive by making use of third harmonic component of back EMF to enable the drive to work satisfactorily over a wide range of speed efficiently. The resistance bank used in extracting the third harmonic component in the conventional technique results in high loss and(More)
