if one of the phase is failed to 3 phase IM. what will happen?
Answer Posted / abhishek sinha
motor runs for some time with less speed because one of the
phase is gone and current increases in two phases,after
some time if no protection act than motor will burn.

what r PID controllers?why they r used?what is there purpose?plz Explain in detail
An 8 pole, 50 Hz, 3-phase IM is loaded to a poing where pull out torque will occur. The rotor resistance per phase is 0.3 ohm and motor stalls at 650 rpm. The slip when motor stalls is A 1 B 0 C 13.33% D 10.33%

I have 4 busbar of 1000 ampere. we use 4 busbar to make 4000 ampere in one phase.my problem is that when we applied 60% load on that then busbar produced high noise.what is the reason of that and how can i minimize that noise.
