A stepper motor driver provides up to 5 A per phase from a high bus voltage with sophisticated current control, delivering high torque over a range of speeds. The STAC5 is intended for use in such ...

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 3D printers, ...

To successfully follow a velocity profile, a motor and drive combination must generate enough torque to: accelerate the load inertia at the desired rates, and drive the load torque at the desired ...

• The inductance in a stepper-motor phase winding limits how fast current rises when power is applied. • Series-resistor current limiting needs higher voltages for faster step rates, but higher ...

When it’s time to specify a high-performance motor that offers both precise positioning and cost efficiency, stepper motors offer many advantages over DC motors thanks to their brushless technology.
