Will resistance help save the motor?

Question

Electronics

Good afternoon.
Actuator - there is such a device in the car. It directly closes and opens the door lock latch.
It is arranged very simply, inside a conventional commutator motor, using a worm gear, rotates a gear, which is connected to a lever with a spring.
In my door, for some reason, the motor fails for the second time. Looks like one winding burned out. I deduced this from the observed "convulsions" when trying to apply power to it, and even rotates for a while if you "spin" it.
Unfortunately, my specialty is not related to motors and mechanics, I can only assume that at a certain moment the motor is hard to rotate and too much current appears in one of the windings for a long time. Because of which she burns out. The severity of rotation, apparently, is due to the fact that over time the lock mechanism has become insufficiently lubricated.
The question is, if I put a resistance on the motor to limit the current, will it save it? If yes, which one to choose?
And then the actuators are not sold separately for my car, I have to buy the whole door.
Also, I noticed that a flat capacitor is soldered to the motor contacts. If it's not difficult to explain why?
Thank you.

Answer 1

1) you need to lubricate the mechanism that drives the actuator. current limitation will lead to the fact that the actuator at one fine moment will no longer have enough strength to do its job
2) the capacitor is needed to suppress interference and to reduce sparking on the collector

Answer 2

The severity of rotation, apparently, is due to the fact that over time the lock mechanism has become insufficiently lubricated.

That's where such a craving instead of a cause to treat a consequence? Better google what kind of lubricant and where to apply so that the motor runs normally.

Answer 3

With resistance, he will not be able to work at all, since he will not give out the power necessary for the operation of the lock mechanism. They say correctly, you need to figure out why he is experiencing overload and eliminate the cause.
