What is the speed of 3 phase IM(Induction motor) at no load?
How will the Motor meet the increased load(Explain through
fundamental)?

according to this above question,when we are connecting a load across motor ,at the time motor will draw more amount of current which will dominant resistance present in the rotor,and hence the power factor will improved which will simultaneously improve the torque.because as we know torque in the induction motor is T=Er*Ir*cos&#966;.

Hi everyone, I'm Lachuu, recently joined automation company as PLC Engineer. I have certain basic question, I request all big gurus and seniors to answer these question. Because this will be very helpful to me as well starters like me. How to design a control circuit (ex: pick & place - my current project) Yamaha robot PxYx series controller RCX222, using 6 cylinder double acting, plc keyence kv p16r 2 expansion unit for input and output each. How to select panel terminal mcb elcb powersupply. My main concern in some projects how to select dc power supply, mcb rcb(I came across dif bt b c d curves, but stil confusing, pls help me :-(. I would really appreciate all who are going respond to this question.

Please help me regarding my one concern. - During earth pit testing we noticed that the Clean earth pit and dirty earth pit showing continuity (Resistance value - 5ohm) . I want to know that if both earth pit have separate location and there is not internal looping between PIT then why such continuity is showing on it . Because of this issue the field side all earthing point showing short. In PLC panel we are providing two types of earthing cable which is coming from separate earth pit (Clean and Dirty earth pit) because of earth PIT showing short our PLC is not complying spec . please help regarding this issues.
