Hi experts
I'm just thinking about starting a new project, where I want to either push or pull a piston with a neodymium or similar magnet in it using a low voltage electro magnet in an H-bridge so I can change polarity at will. Compressed air is not an option but I do have the possibility of using a relatively effecient battery.
I don't yet have the specs for the thingy, but my design limitations are, so far:
Voltage: Max 15V (but preferebly 12V)
Current: Up to 40A
Stroke length: ~7.5cm
Stroke frequency: 15-25 strokes/second
Apart from not knowing whether such a project can even be realised (due to currently lacking knowledge of magnetism and mechanics - But I'll study up on that), I wonder if I'll have to make the electro magnet myself or if there's somewhere I can find such a fella (by fella I mean electro magnet, but I guess since I now spent many more words explaining my abbreviation, I might as well not have abbreviated it in the first place... Dang... ).
So what do you think:
- Is such a project possible, judging from the few specs I have?
- Should I make my own electro magnet or buy one (and if so, where? Links are appreciated).
Thanks in advance for your thoughts.
