How to choose a stepper motor driver? Determine the rated current of the stepper motor used, and the maximum current of the driver selected with it cannot be lower than the rated current of the motor. Because the output current of the general drive can be set within a certain range, if the output current of the selected driver cannot meet the rated current of the motor, the motor may not have enough output torque.
How to choose a stepper drive brand?
But most of the brands of drivers are very compatible, such as subdivision, power supply voltage, output current, control signal voltage, etc., the range is very large, joint venture brands such as: Dongguan Aiwei (Italy), Mingzhi (Amp America), so these basically do not need to be considered. Instead, the most important thing to pay attention to is the control mode of the driver side: pulse, IO, bus (ethercat, profinet, 485), self-programming and so on.
