The slip ring three phase induction motor are started by inserting resistances so, the stator winding can be connected either in star or delta. The winding wound on the stator of three phase induction motor is also called field winding and when this winding is excited ...
Electrical Signature Analysis (ESA) & Stator Winding Issues (Part III) Following publication of Parts I and II of this series (Oct. 3, 2020, and Oct. 9, 2020, respectively), we continued our literature search for information on stator analysis (from academic and other types of technical papers). And, unfortunately, we continued to come up with ...
asymmetrical winding arrangement AWA), or to set various stars that overlap in space [6]. It is possible to reconfigure a stator with SWA and even n, by swapping the polarity of opposite phases, so that it becomes equivalent to the last type (overlapping windings), as done in [23] for n = 6. This makes it possible to use just n/2
