Dynalco DYNA-GEN Flywheel Generator System - Manual (Page 3)

System Overview
The FWG-1200 Flywheel Generator System is designed to provide power to medium and high
speed industrial engines. There are no wearing parts because there are no bearings, shafts, or
couplings. The FWG-1200 can simultaneously power other products including engine shutdown
panel, air/fuel ratio controls, and other auxiliary components. The FWG-1200 is CSA approved for
Class I, Division 2, Groups A, B, C & D hazardous locations.
The FWG-1200 is made up of three subassemblies: the Rotor Assembly, Power Coil and Power
Supply Module. The FWG-1200 obtains power from the changing magnetic field created by
magnets (mounted in the rotor assembly) passing by the power coil. The output of the Power Coil
is wired to the Power Supply Module which provides a nominal 12 VDC output. The FWG-1200
flywheel generator system provides up to 8.0 Amps total depending on engine RPM. There are (2)
outputs which combine to provide the 8 Amp output current. The “Ignition” output is rated at up to
2.0 A which is used to provide power to the ignition system only. The “Main” output provides up to
6.0 A for providing current to the engine panel, including AFR controller, shutdown devices,
scanner / annunciator as well as supplying battery charging requirements.
