Induction motor: "The single coil of a single phase induction motor does not produce a rotating magnetic field, but a pulsating field reaching maximum intensity at 0 degree and 180 electrical."
I understand that splitting the phase using capacitors produces a Rotating magnetic field in order...
thank you for your replies. I'm trying to get a picture in my mind but some pieces are missing in the puzzle.. During Machines class long ago, we had this diagram of phasors as shown in this link https://www.allaboutcircuits.com/vol_2/chpt_13/9.html . I once interpreted them but now seem to...
ok may I infer that Torque and current aren't directly proportional? Because the rotor resistance decrease the current but increases torque. I see from the source I posted(allaboutcicuits), that the resistance increase helps in shifting the occurrence of peak torque to the start. So maybe I...
I'm unable to find the link source which led me to ask this question, but I found a similar source:
**broken link removed**
I quote the second paragraph, "It can be seen from the plots that a high rotor resistance will provide a high starting torque, leading to rapid acceleration of the...
While trying to understand the concepts of Induction motor and the specifics, I read that resistance(a good/High value i.e.) is required so that good amount of torque is produced, to start the rotor..
Apart from the mathematics, is there any imaginative or analogy-type approach you could use to...
Thanks a lot!
From the replies, I'm getting a sense of where and why they're used. My understanding is that DSP is all about getting in some digital data and then performing some complex calculations as needed and get it to the output..More of repeated calculations in some sense..like music...
Hi
I have some basic idea about these processors and controllers. I find a lot of info on the internet and now I have an idea as to how they differ. DSPs and Microprocessors in their architecture and functionality and controllers with their ability to hold program memory, thereby execute more...
What does this mean? Also my question is for a single phase system, so As you've quoted, it does seem that the neutral traces its path to the power station(or in a Delta-star-neutral transformer feeding my home, neutral goes to the neutral of the star connected Low Tension side I assume) . Now...
In a three pin plug socket-the ones with earth, live(or hot) and neutral, I see the reason behind "earth" being grounded for safe passage of current that has leaked to the equipment's body to the earth. If that is right, then I learn that the "neutral" point is also grounded? If So, then how...
ok things seem clear now! I found Mutual inductance (the absence of it in DC) a good way to sum it up. And thus it seems AC shares but DC keeps everything for itself and burns!..That along with the details as pointed by all you edaboard members has clarified my doubt... Thanks everyone!
How does it avoid a short circuit condition in case of AC then? An explanation in Magnetizing and inductive components of current ..along with the reactance.. will be true right?? I know i'm kind of getting close to the logic but questioning things again!!!
Why does a transformer supposedly burn out when supplied with DC? I did do some searching and found explanations relating to emf as e=d(flux)/dt., i.e. change in flux for emf. Change in flux didn't happen in DC ...but what makes that the reason for transformer not to burn(or wear out) in AC...
So finally..will the fan roatate in the opposite direction with a starting "inductor" as it would with the usual capapcitor? Because the starting current would lead while using a capacitor and lag while using an inductor.. So does that have to do with direction of rotation?
thanks milind! but i felt so because as you mentioned, running winding current lags behind starting winding current because of the capacitor. Hence by replacing with inductor, the running current would lead right? So it would produce a rotating magnetic field in the opposite direction and hence...
