On Stability of Open‐Loop Operation without Rotor Information for Brushless DC Motors [PDF]
Mathematical Problems in Engineering, 2014 Open‐loop operation mode is often used to control the Brushless DC Motors (BLDCMs) without rotor position sensors when the back electromotive force (EMF) is too weak due to the very low rotor velocity. The rotor position information is not necessary in this mode and the stator windings are supplied with voltages under a certain ratio of the amplitude ...

Comparison of Fault-Tolerant Operations for Permanent-Magnet Hybrid Brushless Motor Drive [PDF]
IEEE Transactions on Magnetics, 2010 The permanent-magnet hybrid brushless (PMHB) motor adopts both DC field windings and PMs for excitation. It not only offers effective online flux control, but also flexible brushless DC (BLDC) or brushless AC (BLAC) operations. The key of this paper is to investigate two remedial strategies for fault-tolerant operations of the PMHB motor drive under ...
