The efforts of the two did much to further electrical engineering — Tesla's work on induction motors and polyphase systems influenced the field for years to come, while Edison's work on telegraphy and his development of the stock ticker proved lucrative for his company, which ultimately became General Electric.

Electric motors convert electrical energy into mechanical motion, pneumatic motors use compressed air and others, such as clockwork motors in wind-up toys use elastic energy.

Electric motors are ubiquitous, being found in applications as diverse as industrial fans, blowers and pumps, machine tools, household appliances, power tools, and disk drives.

Electric motors may be classified by the source of electric power, by their internal construction, and by their application.

Electric motors of increasing efficiency were constructed throughout the 19th century, but commercial exploitation of electric motors on a large scale required efficient electrical generators and electrical distribution networks.

Electric motors need overcurrent protection to prevent damage from over-loading the motor, or to protect against short circuits in connecting cables or internal faults in the motor windings.

The use of electricity alone to power boats stagnated apart from their outboard use as trolling motors until the Duffy Electric Boat Company of California started mass producing small electric craft in 1968.

* Electric outboards and trolling motors have been available for some years at prices from about $ 100 ( US ) up to several thousand.

* Electric motors and generators

Category: Electric motors

Electric motors have been used on submarines and electric boats and have been proposed for energy-efficient propulsion.

* Electric motors and generators: Some electric motors rely upon a combination of an electromagnet and a permanent magnet, and, much like loudspeakers, they convert electric energy into mechanical energy.

Electric motors allowed also more flexibility in manufacturing and required less maintenance than line shafts and belts.

Electric motors and generators are commonly referred to as electric machines.

Electric motors are found in applications as diverse as industrial fans, blowers and pumps, machine tools, household appliances, power tools, and disk drives.

Electric motors may be classified by the source of electric power, by their internal construction, by their application, or by the type of motion they give.

Electric motors of increasing efficiency were constructed from 1821 through the end of the 19th century, but commercial exploitation of electric motors on a large scale required efficient electrical generators and electrical distribution networks.

Electric motors applied in agriculture eliminated human and animal muscle power from such tasks as handling grain or pumping water.

Electric models are powered by small but powerful electric motors and rechargeable nickel-cadmium, nickel metal hydride, or lithium polymer cells.

Naturally, enterprises of the size of General Electric are in a position to structure their prices in such a way that the relatively small competitors can be forced to the wall in a very short time.

On June 26, 2009, Jeff Immelt, the CEO of General Electric, called for the U. S. to increase its manufacturing base employment to 20 % of the workforce, commenting that the U. S. has outsourced too much in some areas and can no longer rely on the financial sector and consumer spending to drive demand.

Electric bains-marie can also be wet, using either hot water or vapor, or steam, in the heating process.

Electric current can be directly measured with a galvanometer, but this method involves breaking the electrical circuit, which is sometimes inconvenient.

" Electric bus " can also refer to:

Electric guitars, introduced in the 1930s, rely on an amplifier that can electronically manipulate tone.

Electric guitars can have solid, semi-hollow, or hollow bodies, and produce little sound without amplification.

His typical Electric Levantine sound can be heard on his album AUTOMATON ( Slave with Ewer Device ) and on the subsequent albums of his 90's trilogy.

Electric fields, electromagnetic pulses ( EMP ), and stray fields from other in vivo electrical devices can all cause interference.

Electric power can also be transmitted by underground power cables instead of overhead power lines.

On June 26, 2009, Jeff Immelt, the CEO of General Electric, called for the United States to increase its manufacturing base employment to 20 % of the workforce, commenting that the U. S. has outsourced too much in some areas and can no longer rely on the financial sector and consumer spending to drive demand.

Although Sousaphones have a slightly more restricted range than their orchestral Tuba counterpart, generally they can all play the same music and usually have parts written in the bass clef and the indicated octave is played ( unlike Double Bass or Electric Bass that sound an octave lower than the indicated note.

The preamp with vibrato was included on the original Fender Rhodes Electric Pianos and after 1970 ( with stereo panning ) on the " suitcase " models ; the " stage " models lack the preamp and the amplified speaker cabinet, but can be retrofitted.

* Electric guitars use magnetic pickups to transduce the vibration of guitar strings into electric current that can then be amplified.

Electric cars are generally considered easier for the novice to work with compared to fuel-driven models, but can be equally as complex at the higher budget and skill levels.

Keaggy has long insisted that such stories are completely unfounded, noting that " it was impossible that Jimi Hendrix could ever have heard me ... We ... recorded our first album at Electric Lady Studios two weeks after his unfortunate death, so I just can ’ t imagine how he could ’ ve heard me.

The " Electric Eel " is an electric passenger boat on which visitors can take a trip through the maze of reed-fringed dykes, normally not accessible to the general public.

This tie, built by General Electric in 1983, can transfer a maximum power of 200 megawatts.

Wethersfield has 35 General Electric wind-power turbines atop a hill at approximately 2060 feet above sea level, which can be seen from NY Route 78 ( Cattaraugus Road ), Perry Road ( CR 9 ), Pee Dee Road, and Poplar Tree Road.

The granite monument for this battle can be viewed at the corner of 1st Street and Electric Avenue in the town of Four Lakes.

Electric string instruments often have an electromagnetic pickup that produces a signal that can be amplified.

Electric stop actions can be controlled at the console by stop knobs, or by tilting tablets or rocker tabs which sit on a hinge, and activate or deactivate an electrical circuit, depending on the direction in which they are pressed.

A series-or serial-hybrid vehicle has also been referred to as an Extended Range Electric Vehicle or Range-Extended Electric Vehicle ( EREV / REEV ); however, range extension can be accomplished with either series or parallel hybrid layouts.
