Drill Motor Speed Difference
Has anyone noticed the huge difference in the drill motor speeds between forward and reverse? We measured the current draw on all of our Bosch drill motors at no-load in both forward and reverse and noticed a big dip in current draw and speed in reverse. Too much to compensate with programing!! Last years drill motor indicated only a very slight difference in current and speed.

Therefore, if any of you are using the Bosch drill motors for your drive system and are experiencing some tracking problems this is the reason. You need to add an additional spur gear to change the direction of your final output on one side to ensure that both motors are turning the same direction.
