Need to build reverse and forward motor with custom speed
Need to build reverse and forward motor with custom speed
(OP)
Hi,
I need a motor that can rotate forward and backward with speed I want. Basically, I want to pull a rope (with motor) about 6 inch in 1.6 seconds and release same about 6 inches in 0.8 seconds.
Sorry, if requirements sounds weird but this is for a project I am trying to make for daughter's therapy.
I believe I would need a motor, some timer chip and ropes. Can you please guide me where should i buy and what should i buy for this project.
Thanks

RE: Need to build reverse and forward motor with custom speed
I would look at a linear actuator, a motor driver, and an Arduino to control the driver. You'll also need a suitable power supply and some way to mount motor.
RE: Need to build reverse and forward motor with custom speed
The rope can have an eye and a thimble over the crank journal, and if the rope is long enough, you don't need a slider, just a few guides.
You have to be _really_ careful if this device contacts the patient.
You probably need a local engineer with some specific experience to guide you.
