A Three-phase four-pole AC machine has 60 coils in the stator and each coil has 100 turns. The coils are place in 60 uniformly distributed slots around the inner perimeter of the stator. The coil is also short-pitched (eg spam of two sides of one coil is 13 slots, less than the pole-pitch). The distribution factor of the phase winding is 0.9566 and the short pitch factor is 0.97814. What is the winding factor of the phase winding, and the effective number of turns for each phase winding.

Winding and Constructions

Alternating Current (AC) winding is generally of the 3-phase type due to the inherent advantages of the 3-phase machine. Armature coils must be connected to the yield balance (equivalent in magnitude and 2/3 of the series phase difference of the rod) 3-phase electromotive forces (emf). The armature should be divided into step-bands to start with slots around the perimeter.In the construction of AC machines, the frame is used as an external protective shield to protect it from environmental conditions. The frame also serves as the outer perimeter, allowing the interior to be easily placed. The static state section of the devices is the stator winding attached stator.
