The problem is most likely more than just the motor, meaning the
mechanical movement needs to be properly cleaned and lubricated too.

You have a "hybrid" movement that is almost identical to the mainspring
powered Bontems movements, with the primary exception being two electric
motors -- one operates the movement and the smaller motor is actually
used to create a pause in the bird singing (there is a notched cam).

These were first made right around the time Reuge acquired Bontems.
The motors on this one were French and marked for the year 1959.  Here
is a link to a video I made in 2014 so you can see the movement in
action: https://www.youtube.com/watch?v=t98oqkr32as
