Electric motors have been used as power sources in
the full range of industries since the directed motor
was invented by JaCobi in 1834 and the induction
motor by Ferraris in 1835.
Particularly, the motors are used for the transport
and washing in chemical industries and such industrial
items as a continuous rolling mill in iron and steel
works, printing machine, weaving machine, machine
tools and crane as well as for an electric fan, pump,
elevator, escalator and the like. The motors have been
important tools to the extent that the life in modern
times cannot be managed without them. |
