Huh. PSU showed up to 4.8xA for “unloaded" movement. What kind of power do you think you'll need, instantaneous and/or continuous?

I wouldn't call it "unloaded", most of the energy goes into the rotor at the beginning of the stroke. The transmission ratio was optimized around a ~1kw motor output power constraint. The duty cycle will be very low though.

Yooooooo. This is starting to look very interesting!
