CD tray moves reluctantly and its not the belt

I had a number of CD players where the tray didn't consistently open/closes.
Usually once it moves it will do its job but to get started in/out it needs a little kick.
The CD tray moves manually pretty stiffly even after lubricating.
I don't see any wear or tear.
The tray belt is not slipping and works properly (tried anyway different new ones but same issue).
Could the reason be the tray motor even though it moves once its in motion ?
Or is there a way to give it more power ? It looks like there is not enough torque.
