I only have a stepper motor driver TB6600 available at the moment, can I use it for control of a a brushed dc motor? I think it should work as I could use PWM. I also want to be able to reverse direction. I looked through the datasheets and online tutorials but I could not find out how to connect the pins and what mode to select.

My question: Is it possible to control a dc brushed motor with TB6600, and if yes, how?

A brushed motor requires a DC voltage to reach full speed and start with full torque then uses it’s armature to self commutate which also results in large BEMF energy released during commutation with only 2 wires to input mux’d to each coil.

A stepper driver always gives 50% duty cycle output as it commutates 1 of 4 phases or full steps to 2 coils and only gives DC when stopped.

Therefore it is incompatible to control velocity with a position control stepper driver.
