Andrew Gordon (Benedictine)
Andrew Gordon (15 June 1712 - 22 August 1751) was a Scottish Benedictine monk, physicist and inventor. He made the first electric motor. Life Andrew Gordon was born in Cofforach, Forfarshire. He was a son of an old Scottish aristocratic family and baptized with the name George. At the age of 12, he travelled to Regensburg, Bavaria, in order to study at the Benedictine Scottish Monastery. As a Catholic Scot, there was no possibility of getting entrance to higher offices in his homeland. In Regensburg, he completed a 5-year general education course of study. Abbott Bernhard Baillie made it possible for Gordon to make education journeys to Austria, France and Italy, in particular to Rome. Gordon returned to Regensburg in 1732. On 24 February 1732 he enrolled as a novice and received the name of "Andreas". In the monastery he began with the study of scholastic philosophy under Gallus Leith, who in 1735 at the Erfurter university was appointed as a Professor for Philosophy. Gordon stu ...

Werner Siemens
Ernst Werner Siemens (von Siemens from 1888; ; ; 13 December 1816 – 6 December 1892) was a German electrical engineer, inventor and industrialist. Siemens's name has been adopted as the SI unit of electrical conductance, the siemens. He founded the electrical and telecommunications conglomerate Siemens. Biography Early years Ernst Werner Siemens was born in Lenthe, today part of Gehrden, near Hannover, in the Kingdom of Hanover in the German Confederation, the fourth child (of fourteen) of a tenant farmer of the Siemens family, an old family of Goslar, documented since 1384. He was a brother of Carl Heinrich von Siemens and Carl Wilhelm Siemens, sons of Christian Ferdinand Siemens (31 July 1787 – 16 January 1840) and wife Eleonore Deichmann (1792 – 8 July 1839). Middle years After finishing school, Siemens intended to study at the Bauakademie Berlin. However, since his family was highly indebted and thus could not afford to pay the tuition fees, he chose to join the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mouse Mill Motor
Froment's "mouse mill" motor was an early form of electric motor, also known as the Revolving Armature Engine. It has similarities to both the synchronous motor and the contemporary stepper motor. As the mouse mill motor was simple to construct and its speed could easily be governed, it was later used to drive automatic recorders in telegraphy. The name derives from the rotor's resemblance to a small treadmill. Their usual size was more to the scale of a hamster than a mouse, but rodents were more common at the time as domestic pests, not domestic pets. Construction The motor consists of a freely rotating Rotor (electric), rotor, surrounded by a number of electromagnets. The rotor is made of a light brass wheel, with a number of soft iron bars or "attractors" mounted around its rim and parallel to the axis. There may be one, two or four electromagnets mounted on the frame of the motor, together with a cam-operated switch for each magnet. Many of the early motors were made ...

Robert Davidson (inventor)
Robert Davidson (1804–1894) was a Scottish inventor who built the first known electric locomotive in 1837. He was a lifelong resident of Aberdeen, northeast Scotland, where he was a prosperous chemist and dyer, amongst other ventures. Davidson was educated at Marischal College, where he studied second and third year classes from 1819-1821, including lectures from Professor Patrick Copland. He got this education in return for being a lab assistant. In the 1820s, he set up in business close to the Aberdeen-Inverurie Canal, at first supplying yeast, before becoming involved in the manufacture and supply of chemicals. He became interested in the new electrical technologies of the day. From 1837, he made small electric motors on his own principles. Exhibitions Davidson staged an exhibition of electrical machinery at Aberdeen, Scotland, and in Edinburgh where it was viewed on February 12, 1842, by the young James Clerk Maxwell. Later he exhibited at the Egyptian Hall in Piccadi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emily Davenport
Emily Goss Davenport Weeks (April 29, 1810October 5, 1862) was an American inventor from Vermont. Together with her husband Thomas Davenport, they invented an electric motor and electric locomotive around 1834. Davenport kept detailed notes and actively contributed to the process of the inventions. Needing to insulate the motor's iron core, Davenport cut her wedding dress into strips of silk to insulate the wire windings. She is also credited with the idea of using mercury as a conductor, enabling the motor to function for the first time. With her husband Thomas, and colleague Orange Smalley, she received the first American patent on an electric machine in 1837, U. S. Patent No. 132. This electric motor was used in 1840 to print '' The Electro-Magnet, and Mechanics Intelligencer'' - the first newspaper printed using electricity. She was born Emily Goss in Brandon Vermont, one of five children born to Rufus Goss a local merchant and Anna Green. She and Thomas Davenport lived ...

Thomas Davenport (inventor)
Thomas Davenport (July 9, 1802 – July 6, 1851) was a Vermont blacksmith who constructed the first American DC electric motor in 1834. Biography Davenport was born in Williamstown, Vermont. He lived in Forest Dale, a village near the town of Brandon. As early as 1834, he developed a battery-powered electric motor. He used it to operate a small model car on a short section of track, paving the way for the later electrification of streetcars. Davenport's 1833 visit to the Penfield and Taft iron works at Crown Point, New York, where an electromagnet was operating, based on the design of Joseph Henry, was an impetus for his electromagnetic undertakings. Davenport bought an electromagnet from the Crown Point factory and took it apart to see how it worked. Then he forged a better iron core and redid the wiring, using silk from his wife's wedding gown. With his wife Emily and colleague Orange Smalley, Davenport received the first American patent on an electric machine in 1837 ...

Moritz Von Jacobi
Moritz Hermann or Boris Semyonovich (von) Jacobi (russian: Борис Семёнович Якоби; 21 September 1801, Potsdam – 10 March 1874, Saint Petersburg) was a Prussian and Russian Imperial engineer and physicist of Jewish descent. Jacobi worked mainly in the Russian Empire. He furthered progress in galvanoplastics, electric motors, and wire telegraphy. Motors Born into an Ashkenazi Jewish family, Jacobi began to study magnetic motors in 1834. In 1835 moved to Dorpat (now Tartu, Estonia) to lecture at Dorpat University. He moved to Saint Petersburg in 1837 to research the usage of electromagnetic forces for moving machines at the Russian Academy of Sciences. He investigated the power of an electromagnet in motors and generators. While studying the transfer of power from a battery to an electric motor, he deduced the maximum power theorem. Jacobi tested the output of motors by determining the amount of zinc consumed by the battery. With the financial assistance of C ...

Joseph Saxton
Joseph Saxton (March 22, 1799 – October 26, 1873) was an American inventor, watchmaker, machinist, and photographer from Pennsylvania. A daguerrotype taken by Saxton in 1839 is the oldest known photograph taken in the United States. Early life Joseph Saxton was born in Huntingdon, Pennsylvania, and first entered as an apprentice to a watchmaker when he was twelve years old. Saxon was the son of a Mr. Saxton, a mechanic, and Elizabeth Ashbaugh, daughter of John Ashbaugh Sr. Career Philadelphia In 1817, aged 18, Joseph Saxton moved to Philadelphia, where he found employment as a watchmaker, engraver, and apprentice in the machine shop of Isaiah Lukens. During this time, he made his first inventions: a machine for cutting the teeth of marine chronometer wheels and an escapement and compensating pendulum for clocks. He also helped Lukens with the construction of a clock for the newly rebuilt steeple of the Independence Hall. In 1884, an anecdote about Saxton's apprenticeship was pu ...

Hippolyte Pixii
Hippolyte Pixii (1808–1835) was an instrument maker from Paris, France. In 1832 he built an early form of alternating current electrical generator, based on the principle of electromagnetic induction discovered by Michael Faraday. Mohamed A. El-Sharkawi, ''Electric Energy: An Introduction, Third Edition'', CRC Press, 2015, ,page 3 Pixii's device was a spinning magnet, operated by a hand crank, where the north and south poles passed over a coil with an iron core. A current pulse was produced each time a pole passed over the coil. He also found that the current direction changed when the north pole passed over the coil after the south pole. Later, acting on a suggestion by André-Marie Ampère, other results were obtained by introducing a commutator which produced a pulsating direct current. At that time direct current was preferable to alternating current. Although Pixii did not fully understand electromagnetic induction, his device led to more sophisticated devices being constru ...
