dirty_d said:Matt, i forgot to ask you another question, how was your larger pulley secured to the shaft originally before the slipper clutch, did you mill a keyway into it, or something that a pin could go into and through the shaft like you have on the slipper clutch halves. oh yea, and how the hell is a keyway machined into a bore? it seems like the only possible way is if you have like a 90 degree gearbox small enough to fit into the bore that has a bit on the end to cut it
Well... it's the fact that there is no easy to buy "package" that's holding people back right now. Once perfected and marketed this will make the alternatives look really lame, but for now we have our "hero's" like Recumpence that have the high tech machining tools necessary to give us a vision of the future.recumbent said:It's reliability, and cost that keep us from choosing RC motors to run our E-bikes.
Done any R/C pioneering yourself, safe?safe said:If you are not a pioneer... just forget RC motors for now... but keep your eyes open because from the technical standpoint this is a big advance.

[Ref: http://www.cnczone.com/forums/showthread.php?t=23291 ]
Atlanta HTD 5M timing belt (width = 9mm; 28 teeth small pulley) @ 1000rpm => 483W
Gates PowerGrip GT3 5M timing belt (width = 9mm; 28 teeth small pulley) @ 1000rpm => 787W
Quite a difference....... seems too much, even - think I'll check it....
My Unite motor is rated at 3.2Nm at 1000 watts.Miles said:31 Pound inches of torque = 3.5Nm
Yeah... that's true. No matter what you will need to adapt whatever you get to fit it to the RC motor and at almost 10:1 geardown that's pretty good.Miles said:There's always the Cyclone one
