Hello everyone , I have a Alien Power Systems 6374 60KV motor and I use Maytech VESC with 12s , do you have any idea how to tune the the vesc because I have tons of cogging the motor does not even start some times 
does anyone have the same problem or can help ? Thanks 
Do you mean when you start from stand still ?
I mean if you give it a little push does it work ?
also from a fast look on Alien’s page they say : MAX VOLT: 10S. Idk tho should be fine with 12 probably :-??
Also post some screenshots from the bldc tool with motor config
60kV is extremely low, even for a hub motor. What kind of gearing are you using?
It’s ok with 12s I pedal push first but still no luck
I currently have the system on a ebike with 9t on the motor , it’s cogging even if I pedal with the motor , I have a problem that the vesc disconnects from PC when the motor is working and I can’t do a proper motor detection ,(I want to make it sensored so it can work perfect without cogging or any other issues but APS 63mm hall sensors are out of stock 
Maytech maybe
Hopefully not Maytech cause I don’t have money for a new one I already killed one 
post screenshots of your vesc settings. Then people are able to help you out
As soon as I get home I will
if you disconnect the pulleys the motor is working ok or still not working ?
You have to get through the motor detection. It is not optional. Check your phase wires. You may have a bad connection. A cold solder joint is all it takes.
I’m surprised no one mentioned sensors. This sounds like normal behavior for a sensorless setup. You just gotta kick push when you start up.
still not working ! motor barely moves at all
i always pedal first it does not have the power to move me otherwise 
It does have the power to move you, it just can’t negotiate the rotor position since you’re not running sensors.
Post up more of your board specs
Without knowing them, I blindly suggest you bump up your motor current settings. 90A motor max will give you much better startup torque
The problem must be in the motor connection , it diassembly the ebike kit and hold the motor with the vesc connected ( mounted not with bare hand) the motor worked for a few minutes ive done the motor detection and i was using the keys D ,I ,RPM just to see if it works , i stop and after i went to press the RPM button again and i saw a spark i diassebly the motor but i didnt manage to find any burn , and now its back to the same it makes a tiny sound and still does not move . im tired of that
