Re: Should the motor winding be shorted to motor axle?

Thanks for the reply. So I guess there is nothing else to do than either re-wind the phases or buy a new motor then? Is it worth re-winding phases? How can I calculate how much wire I need? I found this post from @Liveforphysics, what do you think, is it worth trying? Is it that easy to chip enamel?...

Should the motor winding be shorted to motor axle?

Hello people of Endless-Sphere, I would like to know if it is normal that there is a short/connection between the motor axle/chassis and the phase wires? Using a digital multi-meter, I'm testing continuity between each of the phase wires and the motor axle/chassis. To be more precise, I cut and remo...

Re: Help: Cycle Analyst speed limiting issue

My problem is fixed. I first replaced the hall cable with new FTP ethernet cable (foil shielding around all the wire pairs at once. Each pair are not foiled.), brand new jst-sm connector. Also made sure the cable shielding foil was connected to the ground pin in order for the shielding to work. I so...

Re: Help: Cycle Analyst speed limiting issue

It sounds like the hall signals are full of noise (probably from being in parallel with phase wires, but possibly from magnetic fields inside the motor itself). Separating the hall wires out of the cable that houses the phase wires, and isolating them with a shield that's grounded at one end (the c...

Hi, I'm seeking help and guidance with an issue I'm having on my ebike setup. My original problem/symptom was something was limiting my acceleration and motor power.

Re: XPD: open-source keywin e-bike lab replacement

Any idea how to connect bluetooth module to controller? I connected it the same way I would with regular USB/Serial adapter.

Re: Welding battery packs in Europe

Hello Schwibsi, @ danoussh If you have the measurements of your frame, I could maybe have a box built for you, that'll fit in there. Except for small battery packs I really prefer solid cases over bags. Well I really prefer to use the Additive Bag V2. I get a more balanced bike, more capacity and ea...

Salut Danoussh, merci bien pour ton intérêt envers mes batteries ;-) 20s8p would just about into these dimensions. But if you need additional room for the box, it won't work, there's about 4mm in height and 1 or 2 mm in lenght left over. In any case, it would be a very tight fit and I'd feel more c...
