Engineering questions/ golf cart electric motor design....
It has got me thinking as I am applying ~60VDC to a motor (AMD7124) that is only "rated" for 36-48Vdc.
1. At what point is too much of a good thing?:help: 60V/72V/90V/144V/???
Yes, I know it will spin faster with a higher voltage, in my case 2800-3000rpm so we should be good there. From other threads 6000rpm is a max safe? limit or something less????
2. I will be limiting the current to 400-500 amps. What is the max current of the AMD7124 say continuous and 30 seconds? or is it more based on armature/field winding temps or brush capabilities?
3. Should I limit input power i.e. higher voltage/less current or lower voltage /higher current????
4. What is the efficiency of these series motors, If I had a data sheet like the AC conversion motors, it would answer a lot of my questions.
