Re: (ET) motor ratings

[Bill Alburty <willaim kc rr com>]

Hello, and welcome, Robert. I am glad to hear you are going to design motor controllers. That would be great. However, I would add some specifications you might consider. We need a controller which will work on all types of DC motors; namely, series wound, shunt wound, compound wound, and all the other combinations. Ideally, the controller would have a feature selector switch to make it compatible with with each of the various winding types, and hp ratings. I know this may be asking too much, but my thinking is that I'd like a controller I can use interchangeably on my  ET or my golf carts, or whatever. Of course we would still want it to be reasonably priced and super rugged. And how about quick-disconnect also, since I'm heaping on so many niceties?

Hi group,

As I've said before I'm designing motor controllers (thanks for the links). I sent an email to Steve Shore asking if he has any info on the motor requirements but if anyone here has the info you have please send it along. I need to know what the max current draw of the largest motor is (E20). Also what's the HP of the E20 motor? I figure once the E20 is designed I can use the same drive for the rest of the 'fleet'.

I know there are controllers around but they are several hundred bucks, once I know what the current specs are I can get a better idea of how to proceed.

Thanks for the help,

Rob
