Problema 105-1    Source:   Adapted from Example 3-2 - page 177 - CHAPMAN, Sthephen J. -    Book: Fundamentos de Máquinas Elétricas - 5ª Edição - Ed. McGraw-Hill - 2013.

Let's assume a simple two-pole generator. The magnetic induction field of the rotor, B_R, is worth 0.2 T and the mechanical rotation speed of the shaft is 3,600 rpm. The diameter of the machine stator is 0.5 m, the length of its coil is 0.3 m and there are 15 turns per coil. The machine is connected to Y. Determine:

a) What are the three phase voltages of the generator as a function of time?

b) What is the effective phase voltage of this generator??

c) What is the effective voltage at the terminals of this generator??
