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 can be run as generators and vice versa, although this is not always practical.

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.

* 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.

South Korean conglomerates, called chaebol, are often compared to keiretsu, but the chaebol conglomerations are much more similar to a Western conglomerate like General Electric than pre-World War II zaibatsu.

Electric locomotives, because they tend to be less technically complex than diesel-electric locomotives, are both easier and cheaper to maintain and have extremely long working lives, usually 40 to 50 years: the last unit of the Italian E626 class, introduced in 1928, was retired 71 years later, in 1999.

* Electric power transformers, which are built with mu-metal shells to prevent them from affecting nearby circuitry

Electric bicycles are very common in many cities of China, such as Yangzhou ; in some areas they may outnumber motorcycles or regular bicycles

Transducer s convert signals from other physical waveform s to electrical Electric current | current or voltage waveforms, which then are processed, transmitted as electromagnetic wave s, received and converted by another transducer to final form.

Electric buses, which use twin trolley poles ( one for live current, one for return ) but have wheels with tyres rolling on a hard surface rather than tracks, are called trolleybuses, trackless trolleys ( particularly in the Northeastern U. S .), or sometimes ( in the UK, as well as in Seattle and Vancouver ) simply trolleys.
