I have an application that requires a servo motor to life cycle a slip clutch for 30,000 cycles at 15 cycles per minute.
The torque would be ~ 7 in-lbs but I may test clutches that could be as high as 25 in-lb.
I have never used the hobby type servo motors. I have a feeling that they probably couldn't handle this type of heavy duty cycling and fail prematurely.
I am willing to spend a few bucks to get a robust motor, but really would like to stick with an arduino as the controller.
Anyone have suggestions on which motor would suit my needs? I know this is a hobby type forum but I really want to use the arduino
on this project. Am I worrying un-necessarily?
If I over size the motor I guess it would not be a problem.
I was looking at the hobby winch motors, they seem pretty strong and give me a lot of rotation.
What do you think?
My hunch is go for a brushless servo motor - nothing to wear out except the bearings. Unfortunately the
drive electronics may be more complex/expensive. Hobby servos are not generally engineered for
continuous use.
Without knowing the rpm its impossible to help further - power rating depends on torque and speed.
Is that 15 cycles/minute actually rotations or is it test cycles?
I would be rotating at 5 RPM.
Stepper motor? But do you need to actually measure the torque?
I will be rotating the torque sensor which will hold one side of the clutch. It will rotate like a crank and rocker mechanism.
