Very great lecture sir. You're one of the few who seem interested in the subject your teaching which is very refreshing. It will be nice to see a video on Synchronous AC Machines.
sir thanks for your explanation in direction of motor rotation. i have doubt in electrical concept. since rotor core in mounted shaft. rotor shaft also carry electrical current. then why we does not fell shock in motor shaft. motor shaft and stator frame also conduct electricity. the why it is not causing electric shock in stator motor frame and rotor shaft. can explain this.....
Dear Satish, appreciate your query: Rotor core is made up of silicon sheet lamination, which does isolate the current flow. Consequently, rotor and shaft are not connected electrically though connected physically. Hope this helps.
thanks for reply sir. but my doubt is not cleared sir - if stator and rotor core is made of silicon lamination which isolate current flow then how eddy current loss happen in stator and rotor core ? if current flow happen in stator core why frame is not getting shock? sorry if i have asked you silly question to you - it is my eager to clear the concept of IM motor.
@@sathishlakshmanan9317 current always follows a less resistance path. as the end rings are shorting the conductors at both ends, so this end ring path will have very less resistance than the core.
