mothers day gifts
Feature:
C045 driver fits for NEMA17-23 two phase or four phase stepping motors whose current is less than 4.5A. Due to double polarity constant current chopping drive technology, it can drive by motor more smoothly and has better high-speed performance than other driver. It has automatic half current reduction, overheat protection, error connect protection functions. Better application effect in equipment of low cost, low vibration, small noise, high precision and high speed. Suitable for many kinds of automatic equipment and instruments, such as marking machine, labeling machine, cutting machine, packaging machine, plotter, engraving machine, CNC machine tools, etc.

Q&A

Question:How to judge the definition of four lines of stepper motor?
Answer:Connect any two wires of the motor together. At this time, the rotor of the motor has resistance. The two wires are in the same phase and can be connected to the drive A+ and A-; the other two wires are still short-circuited. , then connect the two lines to B+ and B.

Question:how is it both common cathode and common anode
Answer:This would mean forward bias of all diodes . But will not specifically without seeing a schematic.
