Hello Gents,
My son has a little project (science) that has us looking to build a mechanism similiar to a shaker (axial vibration)that works at ~10hz, force amplitude of 1-3lbs, constant duty cycle (okay, i think that is it). Part of the task is to find resources for information. Therefore....
It has to be somewhat home-made except for the windings,etc. I purposed a heavy coil winding on a hinged system with stoppers (reversing poles). Our problem is what size and type of coil ($$?). Also, questions such as, what is the limiting cycle time? (i.e. can it cycle at 10hz), what else don't we know?
He came to me...I came to you.
Thank you ahead,

You don't say what kind of motion you are expecting from the shaker, i.e. sinusiodally, or what? If you just want it to flip-flop back and forth then you can make quite a simple driver circuit, but if want it to follow a waveform you will need quite a large power amplifier.
Hope that helps.....

I appologize it's sinusoidal. If I recall my speaker classes then we are talking about a coil and perm mag config? what do we use for a signal driver?
Heck maybe a motor and piston set up would be more effective. Although, it would increase the complexity of the item.
