: Hi, im building a rail gun and I am using capcitors to power it, but i
: also want to use a compulsator to compare the results and see which is
: better. If anyone has any detailed information about complusators by all
: means tell me. thanks.

: Pete,
: A compulsator is the short name for a Compensated Pulse Alternator, a
: special purpose high current device that's designed to rapidly convert
: rotational energy stored in a large flywheel into a huge pulse of
: electrical energy. The device uses very heavy windings and special
: inductance cancellation winding techniques that allow it to deliver a
: very fast rising heavy current to a low impedance load (such as a rail
: gun). Because they must handle extremely large magnetic forces and
: torques, compulsators are very heavy, custom made devices that are
: beyond the reach of a casual hobbyist. The world leader in compusator
: work is the Center for Electromechanics in Austin, TX.

: While it may be possible to convert a large (surplus) motor into a high
: power alternator, the challenges to convert it into a true compulsator
: would be formidable. For details about how compulsators work and how
: they are constructed see the following patents: #4200831 and 4935708.
: For considerably more technical discussions about some of the design
: considerations that go into building and using compulsators (from one of
: the experts at the Center for Electromagnetics), go here:

: As you can see, high voltage capacitor energy storage systems are
: child's play compared to the design and construction of large
: compulsators... :^)
