RE: [TCML] Motors

The power needed for an RSG motor is dependant only on the mass, or more accurately, the rotational inertia, of the rotating disk.  The KVA of the coil is irrelevant.

I've always been bewildered by folks using HUGE motors on small coils.  From a purely aesthetic perspective, it seems silly to have the RSG motor consuming a significant portion of the total power.

For NST-powered coils, a propeller gap is adequate to handle the power and is much easier to build.  If you are leaning towards a sync RSG, you want either 1800 or 3600 (preferred) RPM.  With a propeller gap, you can use as small a motor as you can find, as the rotor is just a single welding rod.  My SRSG may be seen at http://www.laushaus.com/tesla/sync_gap.htm.
