This Design Idea further develops a previous one integrating a stepper-motor driver in a CPLD (Reference 1). However, this idea integrates not only the driver, but also a simple one-axis stepper-motor ...

After using an oscilloscope to confirm that stepper motors driven backward produced an alternating current, University of Maryland senior Josh Sheldon decided to turn the resulting waveforms into ...

We always think it is interesting that a regular DC motor and a generator are about the same thing. Sure, each is optimized for its purpose, but inefficiencies aside, you can use electricity to rotate ...

Based on the Motorola (now Freescale) heavily used but obsolete SAA1042 stepper-motor-driver IC, this Design Idea describes a CPLD (complex-programmable-logic-device)-based implementation of a stepper ...

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 ...

Engineers rely on motion-control devices to improve efficiencies and production rates on automated factory floors, or at least maintain them. One family of such devices, stepper motors, is widely used ...

Improved microstepping accuracy, and lower motor audible noise and heating results from advanced techniques for current management. Stepper motor motion systems, formerly relegated to low-speed, high ...

3D scanners aren’t cheap, and the last thing you want to see after purchasing one is bad data. But that’s what [Dave Does] and others were getting from their Revopoint POP scanners until some communal ...

ACS Motion Control has strengthened its line of EtherCAT network products with the development of a dual/quad axis pulse/direction drive interface module (PDICL) that delivers a closed loop motion ...
