They have an inbuilt regulator and will take 3.7 volts to 18 volts.
Full operating voltage is 5 volts, anything over 5 volts gets turned to heat, run them on 5 volts, I use a Nokia phone charger rated at 350mA and they will run all day with no heat. Got about 5 or 6 fitted to machines and at the end of a day you can hold them in a closed fist and they are just warm.

Friday nights episode.
New inverter wired up and test run.
Backed off to 6,000 drops the noise a bit which is mainly fan noise, might pay me to reduce the fan diameter but see how it runs and cuts first.
Conversion plate made and bolted to the head casting with countersunk screws and motor fitted.
need a new set of holes drilled as it's about 40mm too high, not a problem.
State of play at the moment, ball screw fitted roughly, conversion plate needs a tidy up as regards cutting the width down, radius corners etc.
Tuesday night job is to make a top plate that will support the stepper inside the column and carry a bearing block for the top of the ball screw.
Been drawn up and belts and pulleys, 2:1 reduction, HTD 5M, on order.
