Help with motor and drivers wiring and setup

[paulus.v]

Hello Gustavo! Welcome to the forum!

There are three types of connection for a stepper motor, unipolar, bipolar series and bipolar parallel. Nowadays most are wired bipolar parallel because they give best performance. Compared to bipolar parallel, the biplolar series has the same torque but it drops twice as fast at high speed. This gives half the maximum usable speed of a bipolar parallel. The unipolar wiring has the same speed performance as the bipolar parallel but only half the torque to start with. Old motors were wired unipolar as the drivers was easier to build and cheaper.



Unfortunately with 6 wires you are unable to go bipolar parallel.

edit: The 50 V drivers are a limiting factor for you regarding speed. Probably you will want to go half coil for better speed even with lower torque. But I'm only guessing as I don't know any details about your CNC build.
