So Maxon Motors politely told me to get lost once I explained my requirements. Maybe they were turned off because I wasn't planning to order thousands of them, or something. They didn't answer my questions as to what part of my requirements weren't suitable. Anyway I'm now looking for...

Okay, thanks for the explanation. So in fact in practice the physical resistance goes down as the voltage goes up, because the current goes down, which would be the opposite of what I said before? I'll be driving this from a fixed battery voltage using PWM, so would that be an appropriate way...

Okay, so in fact opening the circuit and allowing no current flow is the way to make the magnet move freely? That's interesting. I'm obviously missing something fundamental in how electric motors work. I know that if you're driving a lot of work with an electric generator by hand, you can...

Well, that doesn't look like what I'm after. From what I can google, it looks like linear actuator is the name for a whole range of linear motors, most of them driven by screws. Also, the broken English on that product's description doesn't reveal very much about how it operates :) However...

I want an electric motor that works a bit like a servo motor with a steering horn on it, like so: http://www.buggy-sport.info/index.php/gallery/image?view=image&format=raw&type=img&id=7191 But it needs two specific properties: - it creates a controllable amount of force along a given axis...
