Right there, I think you have a problem. This is a high speed motor.
At 24 V, it will already be going almost 4000 RPM. Maybe if used with
20 TPI screws it might actually work out OK, though. But, it would
need a very high belt reduction to work with more common 5 TPI
ballscrews.

It is pretty important to know the maximum peak current on all permanent
magnet motors. If you exceed the peak current, even for an instant,
the magnets can be 'erased', runining the motor.
