Automatic voltage regulating system in brushless generator
First Claim
1. An automatic voltage regulating system in a brushless generator comprising a permanent magnet provided on the stator side and constituting a field of an exciter generator portion, an exciter generating coil provided on the rotor side, a rectifier for rectifying a voltage induced in the exciter generating coil, a field coil of the main generator provided on the rotor side and excited by the rectifier output, and an armature coil of the main generator provided on the stator side, wherein a permanent magnet and a control coil are provided in the exciter field, and an automatic voltage regulator portion is is provided for detecting the output voltage of the main generator and supplying a controlling current to the control coil so that fluctuations of the output voltage of the main generator is absorbed through the control of the control coil, wherein an auxillary coil whose electrical angle is 90°
- apart from that of the armature coil of the main generator is provided to supply a voltage induced in the auxillary coil to the automatic voltage regulator portion as a power source.
