Electric motor failure. Vibrates and doesn´t work

Power System
1

I have had this motor for a couple of years and used to work fine. With a fully charged battery I connect the system everything seems to be fine on the controller, but when I put some power on the controller the motor vibrates instead of spinning.

Any advice on what to check or how to solve this?

there is a missing phase connection from esc to motor. 3 cables. 1 cable will have contact problems.
