I think I recall an electric vehicle event coming up this month in Washington state. Anyone know about this?

I think there's going to be some sort of "MOther Earth News Fair" in Puyallup, WA. I think I'm going to be talking at it! I think it was yesterday! ya! It was super fun, by the way.

Paul, which controller and driver are you running this from? I have your last code working on the breadboard, but, it needs some more stimulus. I had to bypass quite a bit of code to get her working with my setup.
Let me know. |

Oh, I just ported the AN908 code from the dspic30f6010 to the dspic30f4011 but without all the extra stuff that was for the development board that it is supposed to be used with. I'm using a mosfet based power section and a control board that I had made quite a while ago. It's in need of revision, but worked when I did the V/Hz test at low current. It spun faster and slower based on the throttle. I had only one of the control boards made at the time because a company had a special deal that they would do anything up to 120 square inches for $25, and that included shipping and no setup fee. But it was a one time thing, and they don't do it more than once. It's the control board in this video:
At about the 8 second point.
The control section pcb/schematic I sent you is the same as the board in the video.
At the 4:35 point there's a picture of the mosfet based power board. It's also needing to be revised, since I accidentally got the stupid silkscreen on the bare copper part, and other little things.
You have it breadboarded?! What did you get working?!?

I would also love to see an open source group effort on a “3-phase Switched Reluctant (SR) Controller”. The architecture for that type of controller is not that much different from AC, the SR can also do regenerative braking. The neat thing about an SR system is that the EV motor is EXTREAMLY simple to make. The SR motor is a just a housing, shaft, end plates, laminated rotor, and laminated stator with coils, NO BRUSHES or MAGNETS !!!
