Yes, my motor and almost all hub motors have the 120 degree commutation angle, but that has absolutely nothing to do with the hall shift angle. Thats where so many get stuck in the weeds.Sattva Ram said:Also they sell it with -60 but the hub motor for which they sell it sure has a 120 degree regular hall arrangement so for a 120 degree normal motor -60 is the way to go. I still dont know why but who really cares if the controller works fine?)
Normally when you order this controller you tell the seller motor specs (watts, pole pairs) and battery specs (nominal voltage and chemistry). They will set the basics needed for it to work like a standard Chinese controller without self learning. So -60 hall shift.
All you need to do if connect it like a non programmable controller, swapping phase and hall wires until it runs forward smooth and quite.
And we know once phase wires are sequenced for forward and the hall waires are sequenced for forward, the only think left is to sync them, which can be done either by moving each phase wire over one or each hall wire over one.
Whichever you do, you shifted the sync 120 degrees each time.
The votol just does that internally with hall shift. Unfortunately they give you 360 choices inside of the 3 you get by swap wires.
The first time I installed my votol i set it up manually, externally, leaving hall shift at -60. Then since i dont like mismatched wire colors, I reconnected the phase and hall wires matching colors and paired the controller with my computer.
I ending up woth both boxes checked and +60 degrees hall shift. I wont be surprised if thats what yours needs,
Setting HDC so the 3 speed works is logical. Cause if you dont set a speed then the controller cannot know what speed it is which it has to set the percentage of. However HDC seems like king. It determines the RPM no matter what the base RPM of the motor is. If you set a higher HDC than the base rpm it will force that rpm no matter what. Which is kinda bad cause how do you even determine base RPM with this controller? If I shut HDC i get like 650 rpm which is waay too much...
Setting the RPM might be logical but if Down Hill Control box isn't checked the speed selection wont work. Why do i need downhill braking for it to work? I don’t. Lol.
