Motor stop spinning

My motor stop spinning. I’m using raspberry pi 4 and navio flight controller. At first I thought it was my 30A ESC and changed them to 40A and the problem continues.

Once I arm the drone, the motor will spin, but I get no lift and then two will stop spinning.

Any advice?

No, without more information, no advice to give.

Which FW versions? how are the connected? etc…
