Multiple Motors

[rswsmay]

There have been quite a few papers put out about using multiple motors in drive trains, matching their speed/torque, gearing, observing max amp draw, etc. I won't bother to regurgitate what has already been stated. I'll just point you to the references you need.

1. JVN's FIRST Mechanical Design Calculator http://www.chiefdelphi.com/forums/pa...er&paperid=252

2. Discussion on joining 2 different motors http://www.chiefdelphi.com/forums/sh...ghlight=motors

The spreadsheet is quite extensive and should be a great tool for you to use in your design.

If I have a 1000 rpm motor gear down 1:2, and a 500 rpm motor running in tandem, and the system is put under load, won't situations occur in which one motor is driving the other? Wouldn't this mean that a two motor system set up this way can acutally decrease speed and/or torque?

Even worse, if one motor is, in effect, "spinning" the other, won't this cause backcurrent to damage the victor?
