[sci.electronics] AC Drive controllers

nivek@rover.ri.cmu.edu (Kevin Dowling) (08/25/88)

Does anyone have pointers to circuits for AC motor controllers?
These are for adjustable frequency drives for AC motors that
are normally synchronous with 60Hz. Some commercial ones have
constant torque capabilities too.

Emerson makes a pretty good line but I'm looking for a cheaper solution!
(Even pointers to surplus or low cost ones would be useful.)

Thanks.
