I have a recliner chair that has a manual arm, I was wondering if there is a way to place a motor on the shaft the arm spins to make it 'electrically actuated'.
What I'd like is for it to freewheel in both directions when it isn't being electrically driven, but yet have massive torque (can be slow) when actuated. The resistance is only over the first small amount of the turn of the arm, the rest sort of carries itself from the weight of the seated person.
Does such a thing exist? What is something I could look at for ideas?
I'd think something like a small motorcycle starter would be enough torque and could disengage with the solenoid to freewheel, but I don't think they can be driven both directions, while also requiring a LARGE amount of current DC rectified. Maybe a washing machine motor?
I do not want to use a long linear motor retrofit into the chair if I can get away from it, as that would not freewheel and would be very slow to go in and out. I would also like to keep the part cost under $100.
The areas in the bright red arrows are the only parts that require any motor input (though very high torque), and I'd want it to be able to freewheel (or be used with the arm as regularly) when the motor isn't being driven.
