First off, I would like to say Welcome back JohnRobHolmes! I always enjoyed discussing things with you. I'm glad to see you back.

From what I gather, there are two types of speed controller motor braking.

1. Regenerative Braking. The AC (Brushless Drive Motor) Forklifts at work use this technology. It does give a short recharge burst back to the battery thus increasing runtime.

2. Shunted Braking. We have two type of forklifts. The DC trucks shunt the energy coming back from the motor while coasting.

One statement on the group of 36 FETS. That would be 2/3 the total in use at any given time. 24 would be energized at once. Two legs out of the 3 are always hot under power.

My 2 cents.
