Here is a motor speed sensor module, the major goal is to check the rate of an electric motor. The module can be used in association with a microcontroller for motor speed detection, pulse count, ...

Recently, I found an interesting fan motor module in a web shop and grabbed a couple of them for nothing. At the heart of the module is an eight-pin L9110 DC motor control chip from ASIC (www.asic.net ...

A modified feedback system for the EcoLine achieves 70 micrometer repeatability while preserving the original coils and power electronics, enabling 45% cost savings. Double-length 500 mm modules ...

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 ...

In Part 1 of this two-part series, we presented a 3-phase, 480VAC motor circuit with its associated controls (Figure). We stepped through a logical, systematic approach to troubleshoot the main power ...

This file type includes high resolution graphics and schematics when applicable. This 8051 microcontroller-based control circuit adjusts the speed of a small permanent-magnet dc motor via photosensors ...
