Thanks Walt. Is there anything I can do to reduce the gear chatter?

Hey everyone, I have an application where I need to take the shaft of a geared DC motor (spur gear box) into a hypocycloid speed reducer, which will be my final output shaft. I know that hypocycloid gears have little to no backlash, however spur gears do have backlash. My question is will my...

MagMike, I am looking to make an electromagnet that I can apply a variable amount of voltage to, that will slowly or quickly, but smoothly attract another magnet, or something magnetic. What I want to do is use some type of spring in-between the electromagnet and the other magnet, or magnetic...

MagBen and EdStainless, thanks much for the replies! This is very helpful

I have been searching all over for the answer to this and I cannot find it anywhere. If I take a permanent magnet, and I wrap a whole bunch of turns around it with magnet wire (copper) and apply a DC voltage to it, will it strengthen the field and/or flux of the permanent magnet?

Thanks for the response. I appreciate it.

Hi, I am experimenting with a solenoid right now for a project I am working on. I understand that the magnet strength of the solenoid is increased by the core material's permeability. I am looking to use an iron core, as I understand that to be highly permeable. However, for experimenting...
