phase convertor

<< < (10/10)

DavidA:
Back to the phase convertor theme; well, nearly.

In the book on single to three phase conversion the author also briefly mentions using a three phase squirrel cage motor as a generator. His example has the motor driven by another motor, but a single phase one.

As there seems to be no electrical connection between the two, I assume that the three phase motor (with it's added capacitors) could be driven by, say, a small Diesel engine: or even a steam engine.
You would, of course,  have to set up governor to keep the engine a the required speed as the load changed.

But it has the advantage of having true 120 degree phase shift between all phases.  And with a bit of additional plumbing it could keep your shed warm.

Has anyone tried this ?

Dave.

Three phase electric motors are frequently used in small hydro-electric systems in the third world. I seem to remember that the only modification is capacitors across the three windings

Andrew,

Thanks for the links.

Yet something else to add to the 'future project' list.

Dave.
