Anyone can help me please-
How can i Designing a motor control circuit to use a DC Motor to behave as torsional spring with Arduino
.for that i need idea and code

2

I have a great idea! why not post the parameters you are designing to, the torsional force, what motor you are going to use for starts.

Hii.. thanks for your response
Actually i just have idea now. I don't know much about this so is it possible to make a code where we can set the value and change parameters.

While you are at it, can you supply a drawing of how you see this device operating?

Yes it is possible, you get to do it. Please realize this is not a free design center. There is a section where you can pay to have your project created etc. What you need to do is do some research and see how to implement your idea and if you can find some solutions. We are here to help not do your design.

A DC motor cannot hold a position like a spring can, except for a linear actuator.
It can move like a pendulum, if you mean that then search for Arduino pendulum.

Sure, you need a motor, a bidirectional driver, some form of feedback element and to implement a spring transfer function on some type of processor.

Does that help?

I doubt it as @niks86290 can't even read about the section he posted in and what it was for.
So moved it to a better place here.

Why would you presume to need a bidirectional driver?

Most likely, the force applied will only be in one direction.

Of course, further details might if forthcoming, prove otherwise. :grin:

Well, you could use a single-ended one, but it's going to be a lot easier to control if you can push in either direction.

It sounds like a really interesting challenge, possibly using some type of dynamic PID.
Certainly not a beginner project, and will involve some interesting mechanical considerations.

12

so please can you explain this briefly

14

You cannot drive high current through a DC motor's commutator and brushes with the motor standing still, they will overheat and burn out or melt.

Do I detect perpetual motion in this project?

No, what OP is asking for is basically a tension controller.
The problem, IMO, is that there's been no apparent research done or any attempt at all to solve the problem, just "I need code."

So I got him/her started on the research :slight_smile:
