Re: Measuring motor current (anyone tried this?)

Any progress on this? We built a rough terrain bot with CIMS and we know we are at or beyond the design limits for our CIMS and Victors, but that is what we had, and so that is where we started. We have 4 motors being driven by 4 Victors and a 55Ahr deep cycle battery. We ran a few hundred yards and measured the temps on the motors and discovered 3 of them at roughly 105 deg F (on 82 ish degree day) but one motor was 160 to 180 deg F! That's definitely an outlier, and we need to look into this further. I really think we need to monitor and record amps on each of the 4 motors - simultaneously. I think that hall effect current sensors is where we are headed http://www.allegromicro.com/en/Produ...sors/index.asp any help would be great.
