\$\begingroup\$

Is it possible to handle (push - pull) say eg., 50 lb of weight using 12 DC V with DIY solenoid. If yes, what do I need to consider? What make piston more stronger to push? To what limits should I extend the coil turns? What equetions should I use? What other options can I use for cheap push/pull?

I searched quite a bit on web, but couldn't find for heavy duty.

Thank you in advance

  • \$\begingroup\$ While electromagnets can lift cars, they do that by closing the magnetic circuit by physical contact. Pushing 50lb any distance - say, several mm - is a MUCH harder problem because of the airgap. Which is why you won't find much online. If you can't design magnetic circuits, either learn, or use linear actuators instead. \$\endgroup\$ – Brian Drummond Oct 24 '16 at 9:24
  • \$\begingroup\$ Thanks. The reason I wrote solenoid is because there is no problem with gap, while on electro magnet there is a gap constraint. Am I Right? (moving part should be close enough to magnet to be activated) I actually need a linear actuator effect, but cheap actuators are so slow, i need something faster as well as stronger. Any other suggestions? thanks \$\endgroup\$ – InGeek Oct 24 '16 at 14:09
