Re: High-force Push Solenoid

Hi, I am having some trouble looking for a push solenoid that I need
for a project.

I am looking for a push solenoid capable of pushing at about 5 kg.
Furthermore, I want to be able to vary this force. I am using this to
push a fully weighted piano key to create different loudnesses, so the
dimensions of the solenoid need to be relatively small. Does anyone
know an appropriate device for this application, or shall I be forced
to make my own?

Thanks for your help.


I have made solenoids in the past from automotive starter solenoid coils.

These flow 20A @ 12V and push ~ 20kg.

Haven't seen a commercial one more than 2kg or so from mmemuri?...momery?...ummm...memmeri...yer, thassit!

Stroke may be a problem too...you will need 10 odd mm to operate a piano key no?

If you make your own solenoids (88 of them?) they can be placed closer together by using long & short actuation rods... _-_-_-_-

And use steel cases to provide a magnetic circuit...the end cap is important in hold applications, but if you are going for a linear force adjustment via current control it may not be needed
