    Machining/modifying motor laminations?

    Trying to understand a little bit about rotor laminations and what if any effect modifications to a lamination stack would have on a motor. If someone wanted to change the diameter of a hub motor axle could the entire stack be machined in a lathe as if it was one big chunk? Is the shape of the...

    Gates CDX belt, any size, even broken

    Does anyone have a gates CDX belt they don't need? I need one to get measurements from. I'll take any length. Belt could also be damaged or cut. Maybe you bought the wrong size? Maybe you accidentally cut it with a razorblade opening the box. Maybe I can give you a few dollars and save it from...

    Gates Belt CDX strength and design considerations?

    Thinking about trying a Gates CDX carbondrive belt in rigid setup mounted to the LH disk flange. Since they aren't cheap I'm wondering if anyone knows the max force the are designed for. How far can I cheat the max rated power of the belt with a high gear reduction? I'd be using a 19tooth...

    Do the old "infineon" controllers gradually reduce current to avoid the LVC?

    Anybody remember if the old "Infineon" controllers reduced current gradually to prevent the low voltage cut from being triggered? I didn't think they were that smart. I thought they would crank out full current until they hit the low voltage cut set point. Just dusted off an old Lyen 9fet trap...

    Engineering ? Drag from Tensioner vs jackshaft

    I know gear reductions through a jackshaft add losses to a system through drag but how does that compare to a single stage with a tensioner? I am trying to compare 2 similar designs. One design uses a jack shaft to locate the final drive to the pivot point of the bike's suspension to eliminate...

    Wireless Crank power meters as torque sensor?

    Been seeing a lot of wireless bluetooth crank spider power meters on the market lately. Has anyone deciphered these major manufacturers' communication such that we could use them as torque sensors for ebikes?

    Combining 2 hub motors into one?

    I ended up with 2 identical 8" scooter motors. I know they arent the best motors in the world but they were free so I'd like to experiment with them. So my plan is to machine a new shaft and combine them into one motor. I'm figuring 2 controllers is best. So here are my questions about doing...

    Geared Hub Without one way clutch?

    I ended up with a hub motor that appears to be a geared hub but has no one way clutch in it. Its engaged in both directions so its capable of regen. I've only dealt with Direct Drive hubs before and didn't know this was a thing. I thought all geared hubs had a one way clutch such that they would...

    Hall sensor magnet pickup ring on shaft LMX?

    I am using the small 30mm LMX motor. I'm having some issues with the hall sensor signal not being clean. I suspect that I am picking up flux from the windings because the sensors are so close to them. I was considering making a small plastic ring with magnets and a stand alone hall board so I...

    Dirt Jump Bikes for Speed? Frame geometry questions?

    Would a dirt jump frame make a good mid drive bike at high speed on trails? Would a dirt jump bike be the perfect solution for a durable playful geometry but still do well on trails at high speed? Seems like the major drawback to Dirt Jump frames for trail use is the seat tube is usually very...
