Adjust the phase current, crank up the microstepping, and forget about it — that’s what most people want out of a stepper motor driver IC. Although they power most of our CNC machines and ...

[Kevin Lynagh] is interested in tiny PCB stepper motors ... although he confesses to burning out a motor driver circuit before stepping back and making some calculations. We covered one such ...

Stepper motor drives are primarily distinguished by three individual properties: motor winding arrangement, drive circuitry, and step mode. The type of driver has a large influence on the stepper ...

Some advanced drivers may be able to provide up to 1/256 of a full step. Micro-stepping provides greater resolution and smoother motor operation, which can reduce the need for mechanical gearing. This ...
