Experimental performance examination of a coherence technique-based numerical differential current relay for AC machine stator windings protection

The technique develops a new design for quadratic tripping curves based on both auto-coherence and cross-coherence estimators, which is established to discriminate between turn-to-turn, internal, and ...

Experimental evaluation of differential voltage protection scheme based on a coherence function applied to AC machine stator windings

A coherence algorithm is used to detect and classify electrical faults in the stator windings of the induction machine in this paper. The approach can definitely define turn-to-turn and internal shunt ...

Making A Brushless DC Motor Winding Machine

Over on his YouTube channel our hacker [Yuchi] is building an STM32 BLDC motor winding machine. This machine is for winding brushless motors because manual winding is highly labor intensive. The ...
