| | | | Iain, How much power do you want for the electromagnets, and how rapidly do you need to switch them on and off? Old-fashioned relays will give you the least power loss, but can't be switched very quickly. They also have a limited life (between 10 (...) (13 years ago, 24-Dec-11, to lugnet.robotics.rcx)

For a linear motor you want to trigger each electromagnet in a series, you ideally you might like a "push-pull" system, where you aren't just turning a magnet on and off, but reversing (...)
