Hello forum!
It turns out that I have an electric gate and it started working erratically, sometimes it opens, sometimes halfway, as the engine buzzes, it does not reach to release the lock solenoid and it doesn't feel like the engine is being forced, but it buzzes and doesn't does it move.
I attach photos of the engine and plate.
If I touch the control, as if it began to do the process, but it only buzzes the engine and sometimes within seconds it would start to open and sometimes I must try several times, to close it costs less, but sometimes it also costs.
My little experience in these types of motors is my opinion that the capacitor can be, but I have the bad luck that is not labeled to know which one to buy, I will have to take it out and see if I can get it.

What do you think?
Am I oriented or do you think it could be something else?
Greetings.
