The project illustrates the control of two unipolar stepper motors using this circuit in full step mode through the RS232 serial port of the PC. The signals from the serial port of the PC is being ...

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 ...

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 ...

Different types of motors need different types of drivers. Requirements for a variety of applications. Selecting the right motor driver is crucial to achieving the required functionality and ...

[Kevin Lynagh] is interested in tiny PCB stepper motors, and after reviewing the various projects and patents to-date, decided to give it a try himself. These are basically a stepper motor that’s been ...

• The inductance in a stepper-motor phase winding limits how fast current rises when power is applied. • Series-resistor current limiting needs higher voltages for faster step rates, but higher ...

Starting on Monday, September 19, and running through September 23, Design News will present the free course, DC Motor Controls with the RP2040 Pico. Each class runs an hour, beginning at 2:00 Eastern ...
