Bought one of those Hoppin' Hydros Big Bad Johnson motors tonight. $5, you gotta love that. Out of the box, it will draw 1.3A on four cells. Not incredibly fast though. So of course I had to tear it apart to try to see what I could do with it.
It has 22 turns of what looks like 26Ga wire. It is also timed more like a 180 motor, with the brushes rotated quite far relative to the magnets.
The first rewind attempt, I wound it like a 130, with 12 turns of 22Ga. It was pitiful in performance, and drew a whopping 6A.
If it performed at all, I would have said bag it and threw it into the FET modded car. Just to see if they could take it. My money says they could. Anyway, second attempt was wound the correct way, like a 180. I wound 25 turns of 26Ga, because at first look, it looked like the wire was 28Ga. Looking at it now, it looks like it is 26Ga. So the rewound motor is slower and draws less current. My fingers are already sore, else I'd give it another go tonight. I think I'm going back to the 22Ga wire, and see if I can get 15 turns on it, along with the correct timing.
