Stepping Down Stepper Motor Output Voltage

[fifty60]

I have a stepper motor driver that outputs 170V at 200 to 25000 pulses per second. The stepper that I am using is only rated for 30V. This is only a hobbyist project that i am working on with parts that I have at my disposal. Any ideas on how i can get these two parts to work together? I don't think any kind of resistive divider circuit would work...

Would a VFD be able to handle this kind of output from the driver? Any input on what could possibly work here?

Can you modify the DC supply in the driver to produce a lower output voltage?

25000 pulses per second is awfully high! Are you sure that is not pulses per minute?
For a stepper with 60 pulses per revolution that would be a shaft speed of 25,00 RPM.

A resistive divider would waste far too much power. With a possible supplement from some diodes to handle the DC component you could use a high frequency pulse transformer or a capacitive divider or series element.
But the driver probably would not like a capacitive load.
It sounds like too much of a mismatch to overcome.
A VFD would be no help at all since the input pulse timing would be totally unrelated to the output.

Looks like I will need to find different components for my side project. Thanks for the input.
