Hello, I really need a way to reverse the polarity of a solenoid, changing the current seems like the best way...but doing this rapidly, with control is the objective, (rapid means 50 to 150 time per second) therefore making "North" into "South"
Thank you ahead, to ANYONE smart enough to figure this out, Sincerely, D....

 

How large is the solenoid?

 

Even better, can you provide a manufacturer's part number for your solenoid?

Without knowing what solenoid you're dealing with, I'll suggest that an H-bridge with a chopper driver (to control current) will be required, and the driving voltage will likely have to be at least several times what the solenoid is rated for.

Along with the solenoid manufacturer and part number, it would be very helpful to know what your intended application is. It may be far less complex to do something like use a motor with an elliptical cam, or offset crank pin.

 

doug,
Reversing the polarity of the standard solenoid will not change the direction of motion from push to pull...if that's what you are trying to do. Either polarity will pull the core.

rapid DC current reversing

so you want to make some kind of 'alternating current'?
