Low power motors for power tools, domestic equipment, refrigerators, vacuum cleaners etc are typically supplied at 220V a.c. 50/60Hz. Common types are: Split-phase induction motor... Read more
When motor direct-on-line started with the stator winding star connected, it will only take one-third of the starting current that it would take if the windings were delta connecte... Read more
When the 3-phase a.c. supply voltages are connected to the three stator phase windings, the resulting phase currents produce a multi-pole magnetic flux. This flux is physically rot... Read more
