THIS WILL GIVE THE EASY UNDERSTANDING OF BRUSHLESS DC MOTOR AND OPERATIONS IN EASY MANNER....
The proposed sensorless method closely resembles the conventional DTC scheme used for sinusoidal
ac motors such that it controls the torque directly and stator flux amplitude indirectly using d-axis current. This method does not require pulsewidthmodulation and proportional plus integral regulators
and also permits the regulation of varying signals. Furthermore, to eliminate the low-frequency torque oscillations, two actual and easily available line-to-line back EMF constants (kba and kca)
