could an induction motor be used for regenerative braking in electric-train control? in this type of application would some scheme have to be devised to obtain low synchronous speeds while braking? would induction-motor drive, therefore, be suitable for passenger service?

in cvt,there are two windings,1a,1n and 2a,2n.in my one project i use only one winding i.e.1a,1n. the other winding is not in use, so i connect it in open delta and want to close it by ibsertibg thermal resistor. the output of cvt is 132kv/115/sqrt3. plesae tell me exact value of resistor, so i may close it to avoid the resonance phenomenin. send me answer on this email adress please. aetcon-po@aetcon.com
