The magnet was made of 18 turns of bare copper wire (insulated wire had not yet been invented). [1] William Sturgeon (/ ˈ s t ɜːr dʒ ə n /; 22 May 1783 – 4 December 1850) was an English physicist and inventor who made the first electromagnet and the first practical electric motor.
Gagné was also involved in applying concepts of instructional theory to the design of computer-based training and multimedia-based learning. [ citation needed ] His work is sometimes summarized as the Gagné assumption: that different types of learning exist, and that different instructional conditions are most likely to bring about these ...
His motor was the first to maintain constant speed under varying load. It was immediately popular and was endorsed by Edison as the only practical electric motor available. His regenerative braking system was important in the development of the electric train and the electric elevator.
Ford Motor Company was simultaneously manufacturing a car model with transmissions made in Japan (by Mazda) and the United States (by Ford). Soon after the car model was on the market ( c. 1950 ), [ 7 ] Ford customers were requesting the model with Japanese transmissions over the US-made transmissions, and they were willing to wait for the ...
Though this theory represented an important leap forward in motor learning research, [1] one weakness in Adams’ closed-loop theory was the requirement of 1-to-1 mapping between stored states (motor programs) and movements to be made. This presented an issue related to the storage capacity of the central nervous system; a vast array of ...
Schuyler Skaats Wheeler (May 17, 1860 – April 20, 1923) was an American electrical engineer and manufacturer who invented the electric fan, an electric elevator design, and the electric fire engine. He is associated with the early development of the electric motor industry, especially to do with training the blind in this industry for gainful ...
American; built a 12-pole electric motor with segmental commutator. [7] [18] [20] US 910: 1840, Truman Cook American; built electric motor with a PM armature. [18] [20] US 1735: 1845, Paul-Gustav Froment: French, engineer and instrument maker; first of various motors; first motor translated linear "electromagnetic piston's" energy to wheel's ...
Heinrich Friedrich Emil Lenz (German: [ˈeːmɪl ˈlɛnts]; also Emil Khristianovich Lenz, Russian: Эмилий Христианович Ленц; 12 February 1804 – 10 February 1865), usually cited as Emil Lenz [1] [2] or Heinrich Lenz in some countries, was a Russian physicist who is most noted for formulating Lenz's law in electrodynamics in 1834.
