I have a 110SM04030 servo motor (maybe made by Changzhou Changhua Electric Motor?) that drives my spindle through a 1 to 1.5 pulley ratio. The servo is rated at 1.2kW, 3000 rpm, and 5.0 Amps with a rated zero-speed torque of 4 Nm. The pulley ratio turns the 3000 rpm of the servo motor into 4500 rpm at the spindle.

The servo motor is driven by a Maxsine EP1 220V servo driver.

The 4500 max rpm at the spindle is slower than I would like. Is it possible to run the servo motor at higher than its rated speed?
