Simulation and fault diagnosis for BLDCM

2013 25th Chinese Control and Decision Conference (CCDC), 2013
Faults in BLDCM (Brushless Direct Current Motor) are difficult to avoid and may result in serious consequences. Effective FDD (fault detection and diagnosis) can improve motor reliability and avoid expensive maintenance. Therefore, the early examination and diagnosis to the motor common fault could prevent the disaster from occurring effectively, which

AC-DC PFC Converter Fed BLDCM Ceiling Fan

2021 International Conference on Sustainable Energy and Future Electric Transportation (SEFET), 2021
Abstract–An AC-DC power factor corrected converter (PFCC) fed brushless direct current motor (BLDCM) fan is presented with high-frequency transformer isolation. A front-end PFCC in series with a VSI (Voltage Source Inverter) is utilized to drive the BLDCM fan with enhanced PQI (Power Quality Indices) at the supply RMS voltage.

GA based PI control of BLDCM Drive

2008 27th Chinese Control Conference, 2008
The brushless DC motor (BLDCM) has a good control performance. The classical PI controller is widely used controller. But the determining of its parameter needs the mathematical model of the system. Usually the exact mathematical model of system is hard to known. This places a restriction on the applying of the commonly used Z-N method to determine the
