    Reading (understanding) electric motor data?

    Thank you very much! ...again! You made it much more clearer for me. The main problem comes from bulgarian/english translation. I mean, here we call "coil" to the "group". And "coil" we called it "section"...but this is not so important. What isn't clear for me is..How did you understand...

    Reading (understanding) electric motor data?

    Hello! I have problem in understanding electric motor data, which is given in the samples calculations of EASA's "AC Motor Redesign" book. Please help me read it. Here are some samples. Bolded are the problem terms. 1) Data: 36 slots, 18 coils, 45 turns per coil, 1#19 wire AWG, spans for two...

    Wire Size Change in Electric motor

    My english is not good enough or my knowledge, but I still cannot get it :( Maybe the first sentence from the scanned page is the explaination? "Whenever the turns in a coil are changed, the wire size usually changes to provide the same slot fill" maybe I should read (translate) it as: If...

    Wire Size Change in Electric motor

    Thank you very much for your answers! So if I understood you correct...The following example is true? If I have to rewind a motor with original data: 1 wire X 0,90 mm diameter, 100 turns it will not change if I made it with 1 wire X 1,00 mm diameter, 90 turns ? http://eldvigateli.com -...

    Wire Size Change in Electric motor

    Hello! The first formula which I read in EASA's "AC Motor redesign" book seems very strange to me. You can check it the attached file or: CM2 = CM1 X (T1/T2), My question is, ok if I change the lenght (turns) and the area of the wire. I am changing also the resistance of the winding, correct...

    AC Motor Verification & Redesign Program

    You have no longer access to the software? Don't tell me you mean, that we should pay for the software (or membership) every year? 1989 DOS program is not EASA's, but from Soviet Union :) About Elin Engineering - yes, it is our family company. We try to maintain quality not quantity. Here you...

    AC Motor Verification & Redesign Program

    Thank you for your friendly answer to my bad english post. "I would say that the cost of EASA membership and the cost of the 'AC Motor Verification and Redesign Program' would be less than the cost of winding the large, form wound motor shown on the home page." We are small family company and...

    Determine motor run capacitor value

    I uploaded it in case, they remove it from the other server. http://eldvigateli.comhttp://files.engineering.com/getfile.aspx?folder=c0361d3f-b67b-4f86-832e-0f5ed79688cd&file=att-43afd4c7d12c8220V.gif

    Determine motor run capacitor value

    Regarding this picture, the work capacitor (not the starting) should be 60-80uF per kWhttp://www.tehcomservis.com/forum/uploads/att-43afd4c7d12c8220V.gif
