Electric Honda Elite
Submitted by reikiman on Sun, 05/27/2007 - 13:25
A couple months ago I found an old Honda Elite frame available for real cheap on Craigslist. I'd just gotten a motor from deafscooter when he was clearing his garage for the trip to China, and was wondering what to do with it. This motor was said to be 48 volt, 4000 watts, and so this Honda Elite frame seemed like the perfect thing. It came already stripped, and when I picked it up the guy turned out to be an EV person himself. His daily driver is a Solectria Force and this Honda Elite was something he'd converted to electric years and years earlier, but he wanted to get rid of.
Can't get much more bare than that.
That's a closeup of the former swingarm. He had put a solid bar where the shocks should be, so the arm doesn't actually swing. As you'll see in a minute that's very important to how I'm mounting the motor. It's also using a belt drive.
What I've been puzzling over since getting this scooter is a kind of round peg in a square hole problem. How do you get the motor (round) to mount to the frame (basically rectangular). I've come up with a workable solution that's seeming to work pretty well.
The scooter came with a small aluminum box (open ends) and I've modified it a bit to serve as a base. Then using those angle brackets I'm attaching the motor to this box. It all bolts together and seems sturdy enough.
Here it is mounted to the non-swing arm.
The problem I'm having is getting the belt to be tight enough. I suspect the belt should be very tight, so it doesn't slip, right? Unfortunately the mounting system for the motor doesn't leave much ability to adjust the positioning of the motor. So what I've been doing is making the holes for the base of the motor mount to be slots instead. As a slot that lets me slide the motor-mount back and forth to get the desired stiffness.
The scooter is now ready to go ..except.. I let the magic smoke out of the controller. Sigh. Also the potbox (a home made contraption built by the previous owner) seems to have gone bad. So... it's gonna be a little while before this one is finished.
