Powerchair Motors for Bikes...Brushless this time

I used to run CrazyBike2 on brushed powerchair motors with right angle reduction gearboxes, and that was ok, with the only real problem being the repeated chain and sprocket mangling from the incredible torque I could get out of them, and misalignment problems I had due to frame twisting (because of said torque).

Well, now I've got a *brushless* powerchair motor, direct drive rather than gear reduced, to try out.  This thread on Endless Sphere documents my exploration, modification, and testing of that motor, and will eventually show it's first tests on CrazyBike2, and it's later testing on the bike it's intended to be one of the various experimental power sources for. 

That bike is not yet named, and isn't finished yet due primarily to not having a reliably-working welder anymore, and secondarily from not having enough time to do everything yet.  There's a thread on it's evolution over on Endless Sphere, showing it's current progress.   The main thing I needed from this frame was stiffness, to prevent the flexing and twisting issues I had with CrazyBike2 with chain-drive motor power, whcih I still have issues with when carrying heavy cargo.  It'll use a mid-mounted NuVinci 171 developer's kit with autoshifting for a "transmission", to help keep power usage down (although it might not actually make it any more efficient due to the losses the NuVinci itself incurs internally). 

Also, to start it out from beginning as a full-suspension, since CrazyBike2 has broken lots of rear wheels while loaded down because of unavoidable bumps, potholes, and road debris, which shouldnt' cause such problems on a suspended wheel.  It will also use a motorcycle (Suzuki dirtbike, acually) rear wheel, which will take a lot more abuse than the bicycle wheels I have used so far.  I just need a good narrow "slick" tire for it, as the wide knobby it has now isn't really suitable for my purposes.

That's my update for now, hopefully I can keep coming back and adding info to the blog more frequently--but if you are a reader of it, and need more, I tend to post on at least one of my project threads on Endless Sphere ebike forums every day, and sometimes on several of them. 

By Any Other Name...

Well, I've never really thought BEMAP was a good name for the project, but I didn't really have any other one. Many names have come up in conversation about this, some of them not very polite, and others not really having anything to do with what it is or will be for.

The best suggestions so far have been either just wierd but interesting contractions of parts of the thing, or other things related to interests of mine and the whole project idea.

Electricle™ was suggested in an IM convo by Melkorka, The Harvesting Maiden of the North™, and is the current winner.

Another was something to do with Skuld and/or her Banpei creation(s) from Ah! My Goddess!, due to her mechanical inclination and especially the often destructive results of the creations' misuse by others. No specific suggestion was made, however, and I have not been able to think of any, either.

Motor-cicle was also suggested, but it was pointed out by someone else that this would be confused with the existing gasoline versions, and that it was spelled wrong. The suggester bowed head in shame and retreated, unfortunately contributing nothing else.

Kill-kill-die-die was rejected with scorn, for obvious reasons.

ScrapCycle was considered for a moment, but not accepted.

Re-Cycle was not adopted either. Though it was clever. In musical circles, it's already used, though that doesn't preclude it's use here.

Tron's Reject didn't meet with much agreement.

I'm still up for suggestions, so please, comment them in!
