There is hardly any field in the world of electro-mechanics that has not found an application for the stepper motor. They are used extensively in the world of model making and as actuators in remote ...

This unipolar stepper motor driver circuit is used to drive a 12V unipolar stepper motor with a current rating of 1.25A. It uses PCA9537 IC, which is a 10-pin CMOS device that provides 4 bits of ...

ST Micro's Markus Ekler explains the technology and derives thermal loss equations that can be used to support design decisions for stepper motor driver circuits. One constant trend in the automotive ...

Two-chip designs combining a microcontroller or DSP with a highly integrated driver IC simplify the design of a stepper-motor controller, while also enabling sophisticated control features that would ...

[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 ...

In this EDN Magazine article, Phill Leyva and Bill Quach of Maxim Integrated Products describe a stepper motor-driver circuit based on Maxim's MAX 9715, a tiny, surface-mount, 2.8W Class D audio ...

The X20SM1436-1 module from B&R can be used to operate stepper motors with operating voltages of 18-60 VDC at rated currents up to 2.5 A. In addition, an integrated current reduction function ...

Higher-than-normal operating voltages give steppers better torque at high speeds — but watch that current! • The inductance in a stepper-motor phase winding limits how fast current rises when power is ...

Toshiba Electronics Europe has introduced the TB67S559FTG 50V/3.0A stepper motor driver IC that supports constant current control with built-in current detection. 50V/3.0A constant current stepper ...

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 ...
