How many revelolutions nema 23 425 oz

The number of revolutions for a stepper motor is infinite as long as the stepper motor coils are being engaged by the driver and that the driver is being sent pulses and that the driver has sufficient power to engage the coils. With that said, all of our stepper motors have 200 steps per revolution, which may be the answer you may be seeking. The steps per revolution can be increased by microsteps using the driver. In some drivers, this can be as much as 256 microsteps which brings the steps per revolution to 51,200 steps.
