Stepper motors are brushless synchronous electric motors powered by direct current that rotate in steps, keeping the rotor stationary under a specific power supply. A well-defined sequence of PWM ...

This post sponsored by Texas Instruments. The DRV8846 provides a highly integrated stepper motor driver for cameras, printers, projectors, and other automated equipment applications. The device has ...

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.

The A4979 flexible microstepping motor driver with built-in translator is designed to operate bipolar stepper motors in full, half, quarter, and sixteenth-step modes, at up to 50 V and 1.5 A. The ...

Stepper motors are now being used more frequently in industrial environments. Increased performance and reduced size make them increasingly attractive, and their application is no longer limited to ...

Motion Control Products Ltd is launching the DMD556 next-generation digital microstepping drive that is claimed to benefit from unprecedented audio noise reduction (by 70%) and smooth low-speed ...

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 ...

IC has two-line Step and Direction interface and efficient DMOS output. Thomas Rowan, Allegro Microsystems, Worcester, Mass. Most microstepping motor drivers require control lines for DACs to set the ...

International certification minimizes the cost and time involved with gaining regulatory compliance for an OEM’s complete system. Approvals include ATEX and IECEx certifications for Class 1, Zone 1 ...

When you think about highly-precise actuators, stepper motors probably aren’t the first device that comes to mind. However, as [Diffraction Limited]’s sub-micron capable micro-manipulator shows, they ...
