Stepper motors generate a lot of back EMF, which increases with the motors RPM. With only 24v fed to the motor controller, you are limiting yourself with regards to max usable rpm of your motors.

If you are concerned with space in your controller box, consider using integrated stepper motors like this one, and run it at 48v. If you look at the torque curve chart, please note the difference between 24 and 48 volts. At 24v, the torque drops to 1.2nm by 250 rpm, but at 48v, the torque stays up above 1.2nm until close to 850 rpm, or more than 3x the usable speed on that motor just by bumping the input voltage up 2x.

However, I would HIGHLY recommend finding the space for the motor / controller mentioned previously. You will get much better performance and be far less likely to be replacing drivers / controllers in the future.

I hope that this helps.
