Designing a Solenoid Driver Circuit - Max Force of 2.75 lb

[Mike Phan]

Hi,

I am designing a solenoid driver ckt. The solenoid can hold a max force of 2.75lb. If I want my ckt drives the solenoid with max force, what current or power the ckt need to draw?

Thanks for any help.

One way to approach this problem is to look up some typical datasheets for commercial solenoids. Google some solenoid datasheets, and see what voltage and current ratings seem to go with what pull / hold forces.

Then after that, you should be able to do your own calculations for number of turns and current to make a B field with a spreading that makes the pull force...
