Re: Hub motor high no load resistance

it could still have a phase shorted to the stator, or even multiple partial shorts to the stator between phases. sometimes these are not evident with a regular multimeter, even if you disconnect the star connection between phases inside the motor, and require a high-voltage "isolation" tester. it co...

Re: Battery pack 60V

So I have bought a battery which is 15 Amp 48v, By calculating some "ebike math" this battery gives only 700 watt to my motor. the batteyr doesn't give any watts to the motor. the controller does that. what controller do you have? what is it's current limit? that is what determines the power to the...

Re: Should I use Cycle Analyst on my build? - Wiring

Thanks guys I agree- It would be great to hookup the throttle but the throttle is resistive 0-5k ohm. The CA wants a 0-5 volt throttle. a 0-5k throttle hooked to the ca throttle input *is* a 0-5v throttle. hook it up and measure the voltage (or watch it on the troubleshooting / monitoring screen of...

That would leave an on-board charger - is it worth it though? I understand it would have to be an Automotive grade one to deal with the weather and vibration, I'd imagine it would be quite pricey, whereas I can pick up a standalone one quite cheap. you can charge with meanwell hlg (or maybe elg) le...

Re: Cecil's ride - 2017 Raleigh Kodiak 1 full suspension 27.5 plus bike with 750w TSDZ2 mid drive and rear rack dog carr

I think I just stumbled across a motorcycle tire that will actually fit a 26 bicycle rim if anyone is interested. Mitas SW-13 2.75" x 22 knobby tire. I believe the 26 bicycle rim is actually a 22" rim, as is this particular tire. I never saw a 22" motorcycle tire before. sw-13.jpg there's a thread ...

Re: "Steer Tube" Alum. Weld Repair

This now has 150% of the tube diameter... but it almost seems like a waste of CF tube to do this. i believe the length vs diameter reference was to the overlap of the tube with the stub coming out of the folding joint. that's not something you can change unless you machine a new folding joint part,...

things like the meanwell hlg series led psus would work for that, as well as for the dc-dc. but they cost more. something like the hlg-150h-12a would probably do what you're after, at something like 11a-12a of output available.

the tube - stud overlap should be at least 1-1/2 times tube diameter. 2 times diameter is even better
based on his measurements in the pic above, the overlap is only about 78%, rather than 150% to 200%. :(
