What is Electro-Mechanical Engineering?
In engineering, electromechanics combines processes and procedures drawn from electrical engineering and mechanical engineering. Electromechanics focuses on the interaction of electrical and mechanical systems as a whole and how the two systems interact with each other. This process is especially prominent in systems such as those of DC or AC rotating electrical machines which can be designed and operated to generate power from a mechanical process (generator) or used to power a mechanical effect (motor). Electrical engineering in this context also encompasses electronics engineering.
Electromechanical devices are ones which have both electrical and mechanical processes. Strictly speaking, a manually operated switch is an
electromechanical component due to the mechanical movement causing an electrical output. Though this is true, the term is usually understood
to refer to devices which involve an electrical signal to create mechanical movement, or vice versa mechanical movement to create an electric
signal. Often involving electromagnetic principles such as in relays, which allow a voltage or current to control another, usually isolated
circuit voltage or current by mechanically switching sets of contacts, and solenoids, by which a voltage can actuate a moving linkage as in solenoid valves.
Before the development of modern electronics, electromechanical devices were widely used in complicated subsystems of parts, including
electric typewriters, teleprinters, clocks, initial television systems, and the very early electromechanical digital computers.
Part of electromechanical modeling
The purpose of electromechanical modeling is to model and simulate an electromechanical system, such that its physical parameters can be
examined before the actual system is built. Parameter estimation and physical realization of the overall system is the major design objective
of electromechanical modeling. Theory driven mathematical model can be used or applied to other system to judge the performance of the joint
system as a whole. This is a well known & proven technique for designing large control system for industrial as well as academic
multi-disciplinary complex system. This technique is also being employed in MEMS technology recently.
