AC induction motors are everywhere, from ceiling fans to vehicles. They’re reliable, simple, and rugged — but there are some disadvantages. It’s difficult to control the speed ...

This library is to use L9110 motor driver. The L9110 is a simple motor driver which only allows forward or reverse. For this it uses two pins of which only one can be HIGH. If both are LOW or both are ...

[Thinking Techie] takes us back to basics in a recent video explaining how magnets, coils, brushed DC motors, and brushless DC motors work. If this is on your “to learn” list, or you just want a ...

Abstract: Stray currents from DC metro systems intrude into the grounded neutrals of large power transformers, posing a major threat to the differential relay protection of transformer. In this paper, ...

All Tesla vehicles are now capable of bidirectional charging (V2X) thanks to an impressive Powerwall competitor, Sigenergy, which can include a universal bidirectional DC charger. V2X, or ...

POTOMAC, Md. (DC News Now) — There’s nothing quite like the 4×400-meter relay in track and field. “It takes very strong mental strength for sure,” said sophomore sprinter Cameron Homer. “You’re a ...

My goal is to make a good library for controlling the TMC7300 chips. To keep things simple, unlike other TMC motor driver libraries (see Acknowledgements), I do not have a plan to support other chips ...

Power relays are specifically designed to handle either AC or DC. It’s important to know the fundamental differences between them before building them into a system. Introduction to AC and DC Power ...

At celduc relais, DC power switching is under control! The IGBT based SSR (SDI range) can switch up to 100 A @ 750 VDC nominal in a fast, reliable and safe way. Here are the main characteristics of ...

This paper describes the development and implementation of a control system for a direct current (DC) motor using the Arduino Uno microcontroller, based on the speed and direction control of the motor ...

What is an automotive relay? In simple terms, an automotive relay is a small cube shaped electronically operated electromechanical switch. It uses an electromagnetic device to mechanically maneuver a ...
