Mcculloch Mac 15rt Trimmer Manual download. I have a 45MW 13.8Kv 60HZ Generator with a Brushless Excitation system on it. The Generator is a 3600 rpm two pole machine. There is a PMG (Permanent Magnet Generator) mounted on the end of the Brushless Exciter that puts out 292Vac at 240HZ to a Brush Prismic A30 Automatic Voltage Regulator (AVR).

In the manual mode of the AVR we can slowly increase the DC current to the Pilot Exciter field from 0 to 5Adc. That DC current is used to excite four (4) stationary field coils around a shaft mounted 3 phase AC Generator. The AC Generator should produce 3 phsae AC voltage which is then full wave rectified by 6 diodes located on a diode wheel which in turn produces 0 to 350Vdc which is passed through to the Main Generator Field. download Compair C30 Manual Manual. The nameplate on the Generator indicates that approximately 2.5Adc should be enough to get to full voltage no load. As the Generator is accelerated to 3600rpm we can see a small amount of residual voltage buildup on the Generator stator.
