Science Buddies, formerly the Kenneth Lafferty Hess Family Charitable Foundation, is a non-profit organization that provides a website of free science project productivity tools and mentoring to support K-12 students, especially for science fairs. Founded in 2001 by engineer and high-tech businessman, Kenneth Hess, Science Buddies features STEM ...
1828, Ányos Jedlik. Hungarian, physicist and unsung father of the dynamo and electric motor; invented the first commutated rotary electromechanical machine with electromagnets. [3] [5] He invented the commutator. In 1828 Jedlik demonstrated the first device to contain the three main components of practical DC motors: the stator, rotor and ...
William Sturgeon (22 May 1783 – 4 December 1850) was an English physicist and inventor who made the first electromagnets, and invented the first practical electric motor. Early life [ edit ] Sturgeon was born on 22 May 1783 in Whittington , near Carnforth , Lancashire , and became apprenticed to a shoemaker.
An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft. An electric generator is mechanically identical to ...
Frank J. Sprague. Frank Julian Sprague (July 25, 1857 – October 25, 1934) was an American inventor who contributed to the development of the electric motor, electric railways, and electric elevators. His contributions were especially important in promoting urban development by increasing the size cities could reasonably attain (through better ...
Rotor (electric) The rotor is a moving component of an electromagnetic system in the electric motor, electric generator, or alternator. Its rotation is due to the interaction between the windings and magnetic fields which produces a torque around the rotor's axis. [1]
An electrostatic motor is based on the attraction and repulsion of electric charge. Usually, electrostatic motors are the dual of conventional coil-based motors. They typically require a high voltage power supply, although very small motors employ lower voltages. Conventional electric motors instead employ magnetic attraction and repulsion, and ...
The discovery of the principle of the reversibility of the dynamo electric machine (variously attributed to Walenn 1860; Pacinotti 1864; Fontaine, Gramme 1873; Deprez 1881, and others) whereby it may be used as an electric motor or as a generator of electricity has been termed one of the greatest discoveries of the 19th century.
