Senior Project, "Model Power System"

Senior Project designed by Andrew Farrington and Eric Dostie.

The Control Circuit we designed applies a voltage to a 24V DC motor. The motor belt drives a 55A alternator from a Geo Tracker. The alternator has had its diode pack removed, so it produces a 3 phase AC voltage. Once a field current is applied, the alternator produces roughly 40VAC phase-to-phase.

The voltage produced by the alternator then drives loads. When a greater load is put on the alternator, the alternator supplies more current. As it applies more current the AC voltage drops. This AC voltage is fed back into the control circuit. The control circuit detects the drop, and increases the DC voltage to the motor. The increase in voltage to the motor, speeds up the motor, and increases the power out of the alternator, which raises the voltage automatically.

You should feed a battery that powers the motor, that powers the alt to feed the batteries........

you should have left it 12v so you can charge a bank of batterys and the moter does not have to run all the time.

nice project!
