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

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.

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