Everything about Electromechanics totally explained
In
engineering,
electromechanics combines the
sciences of
electromagnetism of
electrical engineering and
mechanics.
Mechatronics is the discipline of engineering that combines mechanics,
electronics and
information technology (
software engineering).
Explanation
Electromechanical devices are those that combine electrical and mechanical parts. These include
electric motors,
loudspeakers, some
fire alarms and mechanical devices powered by them, such as
calculators and
adding machines;
switches,
solenoids,
relays,
crossbar switches and
stepping switches.
History
Early on, "
relays" originated with
telegraphy as electromechanical devices used to regenerate telegraph signals.
The
Strowger switch,
Panel switch and similar ones were widely used in early automated
telephone exchanges.
Crossbar switchs were first widely installed in the middle 20th century in both the
United States and
Britain, and quickly spread to the rest of the world.
Paul Nipkow proposed and patented the first electromechanical television system in
1885.
Electrical typewriters developed, up to the 1980s, as "power-assisted typewriters." They contained a single electrical component in them, the motor. Where the keystroke had previously moved a typebar directly, now it engaged mechanical linkages that directed mechanical power from the motor into the typebar. This was also true of the forthcoming IBM
Selectric. At
Bell Labs, in the 1940s, the Bell Model V computer was developed. It was an electromechanical relay-based monster with cycle times in seconds. In 1968
Garrett Systems were invited to produce a digital computer to compete with electromechanical systems then under development for the main flight control computer in the
US Navy's new
F-14 Tomcat fighter.
Modern practice
Today, though, common items which would have used electromechanical devices for control, today use, less expensive and more effectively, a standard integrated circuit (containing a few million transistors) and write a computer program to carry out the same task through logic. Transistors have replaced almost all electromechanical devices, are used in most simple feedback control systems, and appear in huge numbers in everything from traffic lights to
washing machines.
