860 maximum phase amps :D Now that would make bad contacts weld together quickly. Or burn down the whole thing. Price difference between 4000W model and 8000W isn't that big so might as well get the 8000W unit. Winter is here soon so it is a project for next spring. Price seems reasonable...

Thank you. I believe it figures everything out during autotune. It also notified me that hall timing offset was something like +7.9 degrees. This motor might have 60 degree hall spacing after all. I had to make a quick'n'dirty forced air cooling for the controller by using two 80mm computer...

New sensors arrived, finally. Tried something simple first: flipped the sensor in the middle upside down. Had to dremel the slot a bit to make it accept sensor that way. Replaced phase wires with thicker ones at the same time. Phaserunner suite autotuned everything nicely at first try. Oh the...

Main problem with hall sensors was they were not working as Phaserunner controller wants. I bet original controller this scooter had did nothing with hall sensors. I can setup Phaserunner totally sensorless and it works as well as previous controller. I'm after smooth torque control. Well tests...

All sensors are facing the same way. I took them off few minutes ago. I will definitely try 60 degree spacing too if none of previous approaches work.

Pulled the endplate off to get better view of windings. Now I think it is wye/star winding after all. Only one bundle of copper wires enter the stator slot when phase winding starts. Haven't cut the wire that is holding fourth protective sleeve in place but I suspect the star point is hidden...

Thank you for the reply. Here are pictures of the winding side. No star point there either. I was thinking of trying that sensors 120 degrees physically apart thing. I got few sets of sensors coming so I could try CA'ing them in place, wire them up with separate wires and see what motor...

Hello, I have a electric scooter which I've been riding for a year now. It was sold here as "Leone Ecopower" and I think it is/was sold as "Evader" elsewhere. I bought it used and previous owner had replaced its original controller. It was obviously some cheap chinese controller but so was the...

I'll share my spot welding results as well. I use 4x 90Ah LFP cells as power source. Lots of power. Already welded lots of nickel to cells with this thing. Everything works well! Mostly 0.15mm nickel and 18650 cells. Welds are clean and nickel tears around the weld if I try to pull the strip...
