4 13107xplain in detail d pr. of synchronous motors? why syn. generators r used for the production of electricity?
4 4496what is the exact direction of current? as we know current travels from higher potential to lower potential,so if we take battery +ve to -ve implies current direction is from positive terminal to negative terminal.,whereas electrons flow from negative to positive as they are attracted by positive ions.current will be the plow of charge but not flow of positive ions.please clarify my doubt friends.

As per the Anchor capstan motor specification, full load current is 200A. starting current is 1750 A and acceleration time is less than 8 seconds. Please guide for selection of cable size.
would the same effect be achieved by reversing the connection to one winding of the induction motor 3-phase?
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
