Tips: How to determine the DC supply power of stepper motor driver?
A. Determination of voltage
Supply voltage of hybrid stepper motor driver is generally a wide range (e.g.: the supply voltage of ATODSP42 is 18-40VDC). The power voltage is generally selected according to the working speed and response requirement. However, if the working speed and response requirement of motor is fast, the voltage value also should be high. However, the ripple wave of power voltage also cannot exceed maximum input voltage of driver, or driver may be destroyed.
B. Determination of current
The supply current is generally determined according to the output current I of the driver. If linear power is used, the power current is generally 1.1-1.3 times of I. If the switch power is used, the power current is generally 1.5-2.0 times of I.

Digital stepper driver works great!

I bought this 2-phase digital stepper driver to use an old stepper motor from a 3D Printer for a couple of projects including a cup turner for my wife's vinyl business. I immediately noticed that it was great quality for the low price compared to other stores. Everything works great!

ATO Responded

Yes, this DSP42 controller can be used for NEMA 11, 14, 17 stepper motor, so it can be used for NEMA 8 Motor, but it would be better to send us your specific parameters of NEMA 8 Motor for more confirmation.
