Waveform of stepper motor drive8/31/2023 Thankfully there are already existing solutions. This electronic device will transform our movement instructions from a controller into a sequence where the winding in the stepper motor will be turned on or off while still providing enough power to it.Īll of this we of course be produce by a microcontroller driving a few FETs but the design and the programming would take time. Therefore we need to use a stepper motor driver. Stepper motors require voltages and/or currents that the controller simply can’t produce. There are a lot of different types of stepper motor drivers but in general, all do the same thing – move stepper motors. ![]() ![]() By itself, it usually does nothing and must be used together with a controller like PoKeys57CNC. So what do these micro-step values even mean?Ī stepper motor driver is an electronic device that is used to drive the stepper motor.How do I choose a stepper motor driver?.
