Abstract |
|
This paper presents a novel method for sensorless brushless dc(BLDC)motor drives, Based on the characteristics of the back electromotive force(EMF), the rotor position signals would be constructed. It is intended to construct these signals which make the phase difference between constructed signals and back EMF controllable, then rotor position error can be compensated by controlling the phase difference angle in real time. In this paper, the rotor position detection error is analyzed. Experiments are implemented on a 16F877A Microcontroller chip as a control core to demonstrate the feasibility of suggested sensorless control. |
