Abstract
An automatic voltage regulating system in a brushless generator comprising a permanent magnet provided on the stator side of a main generator and constituting a field system of an exciter generator portion, an exciter generating coil provided on the rotor side of the main generator, rectifier for rectifying a voltage induced in the exciter generating coil, a field coil of the main generator excited by the output of the rectifier and provided on the rotor side, and an armature coil of the main generator provided on the stator side, and characterized in that the permanent magnet and a control coil are provided on the exciter field system, and an automatic voltage regulating portion which detects the output voltage of the main generator and supplies the control coil with a controlling current is provided so that fluctuations of the output voltage of the main generator can be absorbed by the control coil.
