Determining the Excitation Voltage of Axial Flux Wound Rotor Synchronous Generator
Abstract: The axial flux wound
rotor generator has field winding that must be connected to a dc voltage
source. By varying the excitation voltage, its electric performance might be controlled to meet the need of a load
voltage attached to its terminal. The designed generator is small-scale
capacity which has 1 kW, 380 V and 750 rpm. The generator has a single
double-sided slotted wound stator sandwiched between twin rotor. The effect of
excitation voltage changes on its performance can be seen from the result of
calculations using the given equations. The calculation results reveal electric
quantities suited with respect to performance of the machine. If the voltages
increase, the losses will decrease; but higher the excitation voltage, higher
the efficiency and the terminal voltage. It has been found out that for the excitation
voltage11 V, the efficiency and the terminal voltage are 85.12 % and 380V
respectively.
