Coil linear actuator control

This is the latest version of my coil actuator. This one offers much more stable and precise movement compared to my earlier versions.

To control it I am using a simple microcontroller (arduino) which controls the power to the coils using a sabertooth motor controller (from dimension engineering)... a cheap and easy to use hobby motor controller for DC motors.

Yes, I'm using magnets. Not necessarily to increase force, but to allow it to go back and forth (steel can only be pulled into a coil but not expelled). I think it was four magnets on each side. About the coils, there are two coils of approximately 1000 turns of 20 gauge wire. Was running 12 volts through it. I think my resistance was around 4.7 ohms on it so probably would've pulled around 2.67 amps.

What kind of controller you were using?

Hi, are you using magnets in the center of the coil to increase force? how many of them? what is the diameter, number of turns, length , and wire your are using in each coil? what currents are you flowing?

thanks!

woow man, make it or let others produce it !
