    Bafang G310 geared hub - 11:1 reduction ratio!!!

    You mean you actually potted the components in epoxy? Was that a lot of effort? And did you remove the gear grease or leave it in?

    Bafang G310 geared hub - 11:1 reduction ratio!!!

    Yeah, I had the same problem. That nut is often on so tight that it can't be loosened, and I could not find a tool that would fit in there to get a proper grip. I wonder if Grin has an unusual tool that gets in deeper.

    Use silicone oil. It's thin, chemically inert and transports heat well. I'm not sure how well the seals will hold it in tho.

    'lightest.bike' 1.7kg 1000w mid drive

    Look at the video at the 1:00 mark. The tension wheel arm deflects slightly when cranking, which can be measured.

    'lightest.bike' 1.7kg 1000w mid drive

    Do you need a crank with freewheel for this? Can you use any kind of battery? What's the maximum voltage?

    APL's DIY axial-flux motor

    Your program really only exports STL? That's very unusual. Forget it. Even if you find something that does this for you, the results will be awkward. Exporting to STL means a loss of information. STP/IGES contain mathematical information, such as circles being defined as circles. STL on the...

    Compact Field Oriented Controller, ASI + Grin, limited run

    This is awesome, Justin! Great for making adjustments on the go, when you don't happen to have your laptop with you :) I do wonder, if you already have OTG and you're planning Bluetooth, wouldn't it be possible to use a smartphone app not only for configuration, but also as a dashboard? This...

    APL's DIY axial-flux motor

    Is the motor going to be open to the outside air? You usually only see that with absolute-maximum-power hotrod builds. Here a fan will be beneficial. But if the motor is going to have a sealed shell, there isn't going to be much room for air to move around. A partial oil fill is going to have a...

    Bafang G310 geared hub - 11:1 reduction ratio!!!

    Yes, I'm aware. We are talking about the G310, correct? I can't tell how you managed to route them out. https://i.imgur.com/mdgisRG.jpg Here's the stator. On the bottom is where the phase wires come in. I'm assuming you glued your temp sensor onto the coils on this side? How did you route the...

    zukster, please take pictures of how you installed the temp probe and how you routed the wires out of the motor. I tried and couldn't find a route to get it out.

    Portable 5-8 amp charger

    May I hijack this thread? I'm also looking for a reasonable charger, but for 88.2V (21s). I could get a Satiator, but those are a bit too expensive for my tastes. Any recommendations? Thanks! Are you absolutely sure this is possible? e.g. put 2x 42V HLGs in series to create a 84V one? With BMS...

    2019 Motor Simulator, Mid-drives and other updates

    Deionized/distilled/purified water will leech salts and metals out of its surroundings and become conductive and corrosive. There's no way around that, even antifreeze or other corrosion inhibitors will only work for a limited time. Water also will wash out the gear grease while itself not...
