Thanks all for this forum. A little experiment I have been working on for years:

Progress was slow until I got the jackshaft idea from building ebikes. Probably breaking all kinds of rules but I am learning a lot. Made a new end plate for the motor, and rewired it to isolate ground and enable reversing. I’ll post the bike builds next. 1st post so apologies if I am embedding wrong.
I garage tested it with a ebike controller at 24v. I then drove around the block by connecting it directly to the pack, starting off in first and putting it in neutral while hitting the contactor. It sagged under 16V at over 750A at one point, but lived. The motor is a direct drive series wound, and the Bosch stall spec is 730A. Any reason I can't rewind this motor into a sepex and run it at 48v?
