    I would kind of like to keep the workshop and the original motor...

    You could use a 3 phase transformer or a VFD, many VFDs will let you vary the output voltage via programming parameters in the VFD software.

    The transformer would likely be the best option if you want to "stay factory", as the Deckel pantographs I have observed use some complicated switching of the motor leads to accomplish different speed ranges. If you opt for a VFD, then it would be best practice to bypass the Deckel speed range switching and control the speed of the motor using the VFD.
