Electromagnetic rotation experiment of Faraday, ca. 1821 [2] Working principle of a homopolar motor: due to movement of negative charges from center towards rim of the disk, a Lorentz force F L is created which brings the entire disk into rotation. The homopolar motor was the first electrical motor to be built.
Makeblock (Chinese: 童心制物) is a private Chinese technology company with headquarters in Shenzhen, China.It develops Arduino-based hardware, robotics hardware, and Scratch-based software for the purpose of providing educational tools for learning.
A piezoelectric motor or piezo motor is a type of electric motor based upon the change in shape of a piezoelectric material when an electric field is applied. Piezoelectric motors make use of the converse piezoelectric effect whereby the material produces acoustic or ultrasonic vibrations to produce linear or rotary motion. [ 85 ]
The switched reluctance motor (SRM) is a type of reluctance motor. Unlike brushed DC motors , power is delivered to windings in the stator (case) rather than the rotor . This simplifies mechanical design because power does not have to be delivered to the moving rotor, which eliminates the need for a commutator .
Donald Trump's Republicans held on to a narrow edge on Friday as election officials tallied the final votes that will determine control of the U.S. House of Representatives, though Democrats ...
The prototype of a chemically driven rotary molecular motor by Kelly and co-workers. The motor by Kelly and co-workers is an elegant example of how chemical energy can be used to induce controlled, unidirectional rotational motion, a process which resembles the consumption of ATP in organisms in order to fuel numerous processes. However, it ...
The majority of registered voters say they accept President-elect Trump’s victory in the White House race, regardless of feelings, according to a recent exit poll. The YouGov/Economist survey ...
After 13 years of civil war, Syria's opposition militias sensed an opportunity to loosen President Bashar al-Assad's grip on power when, about six months ago, they communicated to Turkey plans for ...
