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 ...

It’s increasingly common for designers to pair stepper motors with motion-control SoCs. In fact, more design engineers than ever are setting up SoCs themselves for motion applications. These chips ...

Part 2 in a series of articles on motor control design focuses on how to reduce noise, one of the biggest challenges, in stepper motors. The amount of noise in a motor depends on the type of motor, ...

Aerotech’s XC4 PWM digital drive is a single-axis motor drive designed for brushless DC, brush DC, voice coil, and stepper motors at up to 340 VDC operating voltage and 30 A peak current. All versions ...

Here's a simple algorithm that uses conventional microcontroller blocks to control commercially available H-bridges to properly commutate a bipolar stepper motor through a microstepping profile.

It is an engineering truism that there is no such thing as a perfect solution—just the best solution for the problem at hand. That holds particularly true for servo motors and stepper motors. Both are ...
