hi everyone...m doin a project on deriving torque expression as fn of slip involving v/f const for a 3 phase induction motor (based on equivalent circuit)..i just need a little guidance or even ideas to start.i really appreciate the help thnk u..tc

 

There was some good discussion of three-phase motors in the LT-Spice forum, at http://www.yahoogroups.com , a while back. You could search the group's message (and files) archive(s) and maybe also email the guys involved.

Also, search at http://groups.google.com and http://www.google.com .
