Stepper motors are often used for positioning since they are cost-effective, easy to drive, and can be used in open-loop systems—meaning that they don’t require position feedback like servo motors.

Stepper motors divide a full rotation into hundreds of discrete steps, which makes them ideal to precisely control movements, be it in cars, robots, 3D printers or CNC machines. Most stepper motors ...

Hybrid stepper motors combine the operating principles of variable reluctance with permanent-magnet stepper motors. The rotor shaft holds one or more pairs of stacked laminations containing many teeth ...

A special closed-loop stepping-motor system eliminates difficulties around resonances and allows less-conservative motor sizing. • Clever management of motor current in a closed-loop stepper system ...

Bipolar stepper motors are used in many applications, from driving paper through a printer to moving an XY stage in industrial equipment. Typically, the motors are driven and controlled by inexpensive ...

From dumbbells to booty bands to treadmills, turning your living room into your personal fitness studio can be a journey packed with product research. We hope you don't mind, though, because we have ...

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.
