Hi everyone,
This is a bit early yet, but I thought I'd start the thread and see what people think. I won't be starting any actual construction for a few months yet, but never the less, I am planning for this build-out.
My goals are this:
1. 0-60 in less than 5 seconds
2. 3 wheel drive (3 C80100 outrunner motors and 3 controllers, one per wheel)
3. Top out at 70mph+++
4. Incorporate custom software in a nano to detect steering angle so that all 3 wheels can pull proportionally based on their arc in the turn.
5. Incorporate some form of traction control so that wheel spin and loss of traction is controlled in the nano.
6. Incorporate a clutch mechanism so both front motors can be mechanically engaged or disengaged at the wheel sprocket with the flip of a lever.
7. Disable both front controllers with the flip of a switch or key turn for lower power, back wheel only riding.
8. 100 mile range.
9. Custom build a 24S pack or packs out of 21700 LION cells.
10. Build this monster on a reinforced KMX recumbent trike frame.
11. Full regen on all wheels.
12. Each controller will have it's own display (android phone) for status and configuration.
13. Each motor will drive from 219 chain and sprockets.
14. Reduce losses via ceramic bearings, cowlings and covers for improved aerodynamics.
15. Custom LED lights for crazy bright lighting.
I think I can accomplish all of this for around $5000 in parts. This project will take 6 months or more to build and perfect.
I have 40 Samsung INR21700 cells coming next week. I've been working with Power Velocity for a good while now on his controllers and have modded quite a few of the 12 fet version for 4kw continuous. I think with better mosfets than the AOT290 which are OK, but spotty on consistency and quality that I can achieve 5kw in a 12 fet controller. I might also use 3 Lebowsky controllers since they are FOC and have a better than 100,000 eRPM limit and I can custom build my own power stage using TO-247 mosfets. I have the boards and MCU's for 3 of the through hole controllers.
I'm expecting to rewind the C80100's or have Alien Power do it for me. There's lots of room on those stator teeth for more copper. When I took this picture I swapped out the shielded bearings for sealed ceramics. All 3 motors will have at least sealed ceramic balled bearings.
I will also be reinforcing the shaft to bell union like this. I've talked to Alien Power about doing this for me and the cost is reasonable. It puts 6 M5 set screws into the shaft onto flats or shallow holes. This picture is from my own work on my Currie scooters motor.
