Electrical Engineering

A 10 hp, 415V, three-phase, 50 Hz, 1500 rpm, squirrel cage induction motor uses star-delta starting and the following data:

Average flux density in air gap = 0.45 Wb/m2 Ampere conductor per metre of armature periphery = 25,000 Full load efficiency = 82% Full load power factor = 0 85 lagging Winding factor = 0.955 Ratio of pole arc to pole pitch = 1.5 Current density = 4 A/mm2 Number of stator slots/pole/phase = 3

Determine the diameter of the stator, the axial length, number of stator turns, size of conductor, number of stator slots and air gap length of the machine.
