Hi Mike and any others that might have the same question,
I've had some crazy stuff going on lately and am planning on refining that design and offering encoders for a bunch of different motors. The first one works great but I have some ideas for improvements.
I don't know how many people have the ability to drill and tap the end of the shaft so one of the improvements will be related to that. I believe Astro's can be ordered with a little extra shaft sticking out of the back and it's easy to re-shaft out-runners so the in the new design, the mag ring will clamp on to the shaft. I'd also like to incorporate a bearing to keep everything aligned, and go to three hold down slots.
If anyone is wanting encoders for their motors, unless it's a 3220, turnigy 80-100, or mini colossus, I'll need at least a good cad drawing of the motor to design from, even better would be to have the motor.
We're trying to get moved and set back up to be financially independent and free from investors again. After getting our hopes built up and smashed so many times, it's time to finance the project ourselves. I'm planning on selling little parts like encoders and custom pcgt pulleys, and doing e-bike conversions to continue to fund the prototype bike build.
With all of that said, I hope to be able to make some stuff available within the next month or so and will post up an appropriate thread in the for sale section.
On another note, I calibrated my CA and the real no load current at full RPM is 1.34 A. This seems pretty close to me and no amount of adjustment will get it any lower. I still haven't had time to get the dyno together or get Burtie's TA going but will very soon!
