5065 motor ebike controller

i have 2 5065 motors that just refuses to run on a ebike controllers it will turn but just judders as it turns. one is 12 pole 16 magnets and the other is 12 pole 14 magnets. both are 220kv has anyone had this problem.
i have tryed 3 controllers and there all the same.

there work fine with a rc esc

Do any of the controllers have a learning function?

yes when i plug them in it just judders.

Sensorless motors? Sensorless controllers?

Did you solve the problem? I have similar situation and I don't know which type of controller should i use. My motor is 5065 270kv outrunner.

Does it do this in all combinations of phase and hall wires?

Do the hall signals from all the wires work, giving good voltage changes as you manually spin the motor (with the hall connector plugged into the controller)?

I forgot to mention my motor is sensorless, so motor connections can't be a problem.
(precisly is that motor: https://www.aliexpress.com/item/New-Arrival-Brushless-Outrunner-Motor-N5065-270KV-1665W-For-DIY-Electric-Skate-Board/32793728617.html?ws_ab_test=searchweb0_0,searchweb201602_1_10065_10344_10068_10342_10343_10340_10341_10084_10083_10618_10304_10615_10307_10301_10313_10059_10534_100031_10103_441_10624_442_10623_10622_10621_10620_10142,searchweb201603_36,ppcSwitch_5&algo_expid=f76079e4-b3c6-44f3-b59c-0c600ee531ed-1&algo_pvid=f76079e4-b3c6-44f3-b59c-0c600ee531ed&priceBeautifyAB=4
and this is driver that I'm using: https://www.aliexpress.com/item/24V-250W-BLDC-motor-controller-E-bike-controller/422302159.html?spm=a2g0s.9042311.0.0.1NiuxK )

What are the specific symptoms?

If it's juddering at all speeds, but spinning anyway, then it might be taking so much current that teh controller is trying to hard limit current to protect itself, and causing repeated cutouts.


If it's not spinning at all and just sits there juddering, the controller may not be in sensorless mode; not sure how you engage that on your controller (most are automatic; if they dont' detect hall signals they go sensorless).

Or the controller may not be able to handle the motor's inductance, so it's current draw is so high when a phase turns on that the controller immediately tries to limit it so much it can't properly drive teh motor. Sometimes this causes the controller's FETs to blow up, too.

Motor is not spinning, only juddering. I think as you said, controller should recognise automatically working mode because there is no wires to set up this mode.

Does anyone push similar set of controller and motor to work together properly?
