The AMIS-30521 and AMIS-30522 stepper motor driver ICs allow engineers to eliminate the need for switches, Hall sensors, flyback diodes, and many passive components in applications ranging from ...

Specifically designed to be used in satellites and spacecraft, vacuum rated motors can be used for communications antennas as well as vehicle controls. The harsh environment of vacuum and microgravity ...

A stepper motor driver provides up to 5 A per phase from a high bus voltage with sophisticated current control, delivering high torque over a range of speeds. The STAC5 is intended for use in such ...

This application note demonstrates how increasing the slew rate of the winding currents in a bipolar stepper motor causes it to deliver more torque at high speeds. To view the application note, click ...

Afamily of unipolar, twophase, stepper-motor driver ICs is designed to simplify peripheral circuitry design and reduce space while maintaining good reliability. The SLA7070MPR Series, developed by ...

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 ...

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 ...

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.

The International Electrotechnical Commission (IEC) defines a servo device as “an adjustable-speed AC power drive system that includes an AC motor integrated by feedback, a converter, and control, ...

[TBJ] is building what he calls a junkbox 3D printer. You can probably guess that he’s trying to salvage most of the parts for the device, and after pulling a stepper motor from an old printer he was ...
