Assume that a four-pole de machine has an armature with a radius of 15 cm and an effective length of 30 cm, and that the poles cover 70% of the armature periphery. The armature winding has 50 coils of five turns each and is wave-wound with a=2 paths. Assume that the average flux density in the air gap under the pole faces is 0.7T and determine the following: (a) The total number of conductors in the armature winding (b) The flux per pole

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.
