achieving right ratio current transformers
Hi guys,
Im busy struggling a bit finding a comprehensive guide to selecting the correct core for a current transforer.
I have a 3 phase brushless dc motor I'm going to run at 6800rpm, thus making the frequency about 115Hz. The motor will pull approx 43A @ 11V which I need to transform to a smaller current using a current transformer, so that a voltage < 5V can be read across my load resister and then put into an A/D converter.
My problem is selecting a core/windings ratio for the transformer.
Ive read a couple of the other similar posts, but it hasn't helped me toward a more specific solution. Please could you help!?
Thanx!
