Hi,
In my search for steppers to drive my router I've come up with the 276oz/in NEMA23 from Automationdirect.com.
I'm looking for a power supply to drive them with and wonder if anyone knows how high I can go on the voltage.
I've heard max should be 20 to 25 times the rated voltage.
Problem is that I don't see a rated voltage in the spec sheet.

I wanted to use the max voltage to get my speed up.

Any suggestions?

I'm thinking 50 to 60v

Thanks

James

The drives and power supply they sell with the motors is only 30V, but they won't tell you the rated voltage. If you actually have the motors, you can measure the coil resistance to determine the rated voltage. amps x ohms = volts

The higher the voltage supplied, the hotter the motors will run. Ideally, you don't want any higher voltage than you need to get your desired performance. Unfortunately, that can be hard to determine.
