Ok. progress...maybe I have it running without stopping. I think it had a poor field connection. It is kinda of noisy and draws 12 amps if C5 is set to 3 and 14 amps if C5 is set top 10. so what's my next move ? run thru the combos again? Txs

Unfortunately C2 can only toggle between 0 and 1. No other settings. Doesn't seem to make any difference if set to 1 or 0. Txs

Yes. the Grin video is what inspired me. i just didn't want to buy a $500 controller.

Thanks. I'm close to giving up. see this thread https://endless-sphere.com/sphere/threads/the-weirdest-controller-motor-issue-and-nothing-helps.113529/?fbclid=IwAR3umTbhJ5PXVVD4V6jL_6W9t77Ek1yz2XCl-fnjoOtKQAKmBuwLx0yA7_E I think its an issue with KT type controllers and my direct drive hub...

Here is something else that is interesting; In the diagram above, the start diagram produces a a smooth rotation but does not go very fast and it is in the wrong direction. I changed the wires in the hall and phase as indicated on the diagram expecting it to change the direction of rotation...

I don't think the battery is sagging. BTW where should i be measuring current? at the battery or at one of the stator wires? txs

Update: At the super fast setting, the motor only runs for about 3-4 seconds and then stops. This may be the correct setting, but it will only run for 3-4 seconds.

The motor is not laced to a wheel at the moment. I am bench testing things, so it is unloaded. I would say the battery can peak at 20 but run at 15 amps. When in super fast mode it draws 22 amps.

That's the problem. I have tried all the combinations (36 in total) (several times) I either get super fast, or super slow or it just clunks or sometimes a clunck with a bit of rotation. I changed C5 to 3 but it did not seem to have any effect. What would be a more suitable controller. I have...

Hi Folks. I hope someone can sort me out. I took a 350w Bionx motor and removed the internal controller. It is now just a plain direct drive motor 3 stator wires and the 3 hall leads plus power and ground. I ordered a KT controller from aliexpress. Thinking bigger is better I ordered the 50a...

Yes exactly I have access to both 120 or 240 at 60Hz. Which model should I order? given the unit is spec'd at 50hz. Does it matter? txs

Hi I am thinking of getting this spot welder. Should i get the 120v version or the 220v version. i live in canada and the 220 is at 60Hz. I think if i get the 220v version it is specedat 50 hz. Not sure if this is a problem I heard 220v is better, but i am worried about the frquency as it...

Maybe i'm wasting my time here but.... My 48v charger blew up. My compressor started up while I was charging and the charger smoked. Here is a pic of the damage. The replacement pieces are easy to source. Problem is I'm working without a schematic and I can't identify the resistor values. Here...

Thanks everyone! That was a ton of very useful information. Much appreciated. What a great forum!!!! Regards

Would you have a link of a supplier for the half twist throttle you reference. Sounds like something I could use. Txs
