Find the rms value of the induced emf per phase of a 10 pole, three phase, 50 Hz alternator with 2 slots per pole per phase and 4 conductors per slot in two layers. The coil span is 150°. The flux per pole is 0.12 Wb (a) 994 (c) 1020 53. (b) 864 (d) 960

Your company is to supply a 50 Hz alternator to a European company. The stator is wye connected with each phase winding having 28 turns of wire. The rotor is supplying 0.173 Wb of flux in the center of pole face. What is the RMS value of the output voltage if measured line to neutral?

A 60 Hz alternator stator is wye connected with each phase winding having 24 turns of wire. The rotor is supplying 0.103 Wb of flux in the center of pole face. What is the rms value of the output voltage if measured line to neutral
