Worcester, Mass. – Allegro Microsystems' A3972 and A3973, in 24-pin batwing DIP or SOIC packages, are dual full-bridge pulsewidth modulation (PWM) motor drivers for microstepping applications. The ...

SAN DIEGO, June 28 /PRNewswire/ — The new high-performance, high-reliability stepper motor drivers from ROHM Semiconductor offer selectable excitation modes—full-step to sixteenth-step with 1.0A or ...

Arcus Technology has developed an all-in one NEMA 11 microstep motor with driver, controller and encoder integrated into the motor’s back cap, minimising external electronics and wiring.

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 ...

Bob Christie examines the EasyStepper concept for driving bipolar stepper motors using an integrated step and direction translator interface. A built-in translator makes devices incorporating ...

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 ...

Brushless servo motors are all the hype these days. But stepper motors still provide a number of advantages while being more cost efficient and robust. Together with precision linear and rotary ...

Many step motor users are faced with a question of whether or not to use microstepping in their stepper motor application. “What will it affect and how will I benefit from it?� one may ask.

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 ...
