Revolutionizing Gears with Programmable Smart Magnets

[Scratch_light]

These are magnets which are programmed according to the motion that is there in gears( transmitting motion from one shaft to other). To improve effificiency of gear; these magnets are kept inside the gear tooth such that whatever may be the error or to achieve constant velocity ratio these are handy. It is just an idea! So please comment for prod and cons and also if this idea is possible.

So what would these magnets pull towards or push against? Currently, the only way to get a magnet which could be turned on/off is an electromagnet, which requires electric current (external power). In the overall scheme, you would need to turn the gear into a rotor of an electric motor, if I understand correctly.

Your description sounds a bit like a stepper motor. https://en.wikipedia.org/wiki/Stepper_motor

Welcome to the PF.

Gear trains are already very efficient. What inefficiency are you trying to decrease?

Thank you for your reply; But the magnets can be programmed according to their motion in the gear or the heat generated; But I am not sure. It was just an idea that came to me while I was sitting in class.

You are attempting to make gear teeth that mesh but don't physically contact each other? Is that correct?

Actually I have seen the gear teeth that you are talking about; it is known as magnetic teeth. What I am thinking is that to avoid errors in gears and to have constant velocity ratio; these are small magnets which are physically present in the gear such that they can overcome this problem.

In what way would the magnets overcome the problem?

• Hold the teeth apart?
• Keep the teeth in contact?
• If something else I haven't thought of, What?

Thank you for your reply
You are thinking in right direction; but one thing which is required for every gear is having constant velocity ratio and not having interferference.

Thank you for your reply. I am just trying for the gear to have less errors such as interference. If this is not possible do tell me.
