Hi ames,I have a motor Sep EX (Schaeff Model no 7600088 MVX4003 Class H) that I need to get a field map for. Is there some place online I can get this? I cant find any info online for this motor nor can I cross it over although I have not spent much time looking for a crossover.
Can I calculate this or figure it out with a scope and a function generator? I measured the field resistance to be 1.1 ohms.
If I cant get this info will it matter much when trying to fit a controller? I knwo it will matter but by how much? My other question is how much current can a field take? Without any info can I just look at the coils and guess based on the wire size of the field coils. The motor I have weighs 83 pounds a picture is located here. http://amesweb.net/photos/main.php?
Do you think 50-80 amps would be too much? Any input is helpful since I am trying to learn.
I remember lots of discussion on this subject. Use the search function and you can find and review much of it. Here is an example. http://www.diyelectriccar.com/forums/showthread.php?t=42896&highlight=saturation+curve This should show the results of the search I used to get to that thread. http://www.diyelectriccar.com/forums/search.php?searchid=333706 Also search for SepEx, Field Map and stuff like that. Do some back ground and I'll help out. What controller do you have?
