Small 900 RPM Generator heads - do they exist ?
« on: April 17, 2022, 02:12:26 AM »
Is anyone aware of a supplier of 8 pole ( 900 rpm ) generator heads in the 2kw to 5kw range ..... anywhere on the planet ?
I would like to put one on my Listeroid.

Oh ! ... and if it's not to much to ask, I want 120/240 AC split phase  :laugh:

Appears that small 8 pole gen heads and hen's teeth are both made of unobtanium. Here's an LEF link from the distant past asking the same. https://listerengine.com/smf/index.php?topic=264.0
BTW, Veggie, if you find one, let us know. We're all interested!
Cheers

900 RPM single phase and 3 phase electric motors are quite available.
The problem as I recall it, is that an electric motor converted to a generator (with the addition of capacitors) is only effective at the load point that matches the capacitors  ???
So it can be done easily enough, but a constant load point must be maintained.
