Good day all.

As per the title, what is the optimum voltage for my M60STH88-3008DF steppers and 752 drivers?
I am still using one of the 42volt ex-BT eBay power supplies.
Thanks for your time.

Best Regards.

Working on the general 32xSqrt inductance rule then 57Vdc is the safe option but I know they will happly take more without shortening the motors life too much.
I nearly always run them at 65-68V mainly because that works out nice for 625Va 24x24 transformer and still keeps a safe margin on the drives 75V limit.

Same here...can get away with 25+25V transformer but no real need to push the limit.
