In engineering, electromechanics combines electromagnetism and mechanics. Electromechanical devices are those that combine electrical and mechanical parts. These include electric motors and mechanical devices powered by them, such as calculators and adding machines; switches, solenoids, relays, crossbar switches and stepping switches. Engineering is the application of science to the needs of humanity. ... Electromagnetism is the physics of the electromagnetic field: a field, encompassing all of space, composed of the electric field and the magnetic field. ... Mechanics refers to: a craft relating to machinery (from the Latin mechanicus, from the Greek mechanikos, meaning one skilled in machines), or a range of disciplines in science and engineering. ... A motor is a device that converts energy into mechanical power, and is often synonymous with engine. ... A basic arithmetic calculator. ... An adding machine is a type of calculator. ... Electrical switches. ... In engineering, a solenoid is a mechanical device that converts energy into linear motion. ... Automotive style miniature relay A relay is an electrical switch that opens and closes automatically under control of another electrical circuit. ... A crossbar switch is an electromechanical device for switching telephone calls. ... In electrical controls, a stepping switch (also called a uniselector; see Strowger switch, below) is an electromechanical device used, most prominently, in early automatic telephone exchanges to route calls. ...


Mechatronics is the discipline of engineering that combines mechanics, electronics and information technology.
