Thanks Noobman,
I have now been looking at a canstack linear actuator - this guy (the non-captive, bipolar, 7.5deg/step, 5V)
It has been rated 5V and 561mA per phase. I don't want to run the motor at full capacity as it will break/run into problems sooner rather than later.
For the purposes of it's performance, if I half the current supplied to it (i.e. set pololu driver current limit to roughly 280mA), should I expect half the torque/force? (From looking at the performance graphs i see that torque is influenced by the speed that it is run at, but the minimum force at the linear travel i'm interested in (0.013mm/step) is still larger than what we need, and that the motor would be run at a constant speed)
