Therefore, for a given DC generator, the induced EMF in the armature is directly proportional to the flux per pole and speed of rotation. A = 2 for wave winding. When choosing the generator output for commercial or industrial applications, select a rating that is approximately 20 to 25% higher than the peak load (for example, if the load is about 40 kilowatts, select a 50 kW genset). Calculate: 1) The starting current. The purpose of the stator is to provide a magnetic field in the region where the coil spins. Cutting magnetic flux by the armature produces EMF based on Faraday's Laws and electro induction. E is the induced e.m.f in any parallel lane within the armature.
