A wye system allows the use of two different voltages from all three phases such as a 230400 v system which. Unbalanced load and cases of faults in electric power systems eg.

A three phase system may be arranged in delta or star y also denoted as wye in some areas.
Three phase induction motor wikipedia. Single phase split phase and shaded pole types and small polyphase motors. Unbalanced phasors can be represented by systems of balanced phasors. In two pole single phase motors the torque goes to zero at 100 slip zero speed so these require alterations to the stator such as shaded poles to provide starting torque.
In electrical engineering three phase electric power systems have at least three conductors carrying alternating current voltages that are offset in time by one third of the period. Fortescue stated his theorem. Using the theory of symmetrical components it is easier to analyze the problems of unbalanced systems eg.
A single phase induction motor requires separate starting circuitry to provide. There are three basic types of competing small induction motors. Sequence components were created to facilitate calculations in unbalanced circuits and systems.
