What Is Electromechanics?
Electromechanics merges electrical and mechanical processes, a synergy powering countless devices, from
household appliances to industrial machinery. It's the heartbeat of innovation, where electricity meets
motion, creating a dynamic field that's constantly evolving. As technology advances, electromechanics
opens new horizons. Wondering how this fusion shapes your daily life and the future of technology? Let's
explore the impact together.

1 Electromechanics is a technology that covers electrical, electronic, mechanical, and chemical systems.
Advanced electromechanics covers physics, electromagnetism, and combinations. The need for this technology
arises from the electromechanic nature of most equipment being used everywhere.

2 Electromechanical systems are used in all aspects of daily living, such as home appliances, support
services, transportation, and massive power generation. For instance, maintaining a car requires knowledge of
mechanical, electrical, and chemical technology. The starter system of a car requires a starter motor that is
engaged by a starter solenoid into the flywheel of the engine for a brief moment. When the car starts, the starter
motor is disengaged.

3 Medical electromechanics is a specialized field that includes diagnostic and life-support equipment. The
maintenance of most medical diagnostic equipment, such as two-dimensional (2D) and three-dimensional (3D)
imaging equipment, requires knowledge of electronics as well as mechanical actuator and positioning systems.
Knowledge of computers is usually needed for the preventive and corrective maintenance of equipment.

4 One electromechanic system that functions as a balance is magnetic bearing. The use of ball bearings to
extend the life of rotating equipment against friction has been practiced for a long time. Magnetic bearing uses
electromagnets and computers to suspend a shaft so that it can rotate freely as held by an alert magnetic field.
The magnetic field is usually a combination of permanent magnets and electromagnets. Ideally in its steady
state, the electrical power needed to support the rotating shaft is zero, meaning that the permanent magnet does
all the work until correction is required.

5 Continuum electromechanics deals with the relationships between electrical and magnetic energy and
fluids. It is intended to produce new solutions by using untapped potentials of various forms of energy and
materials. Huge research and development opportunities are available in tapping combinations of electric,
magnetic, and chemical energy.

6 Electromechanics of particles deals with the interaction between particles, energy, and chemical systems.
For instance, the total cleaning of oil spills is done by nature at its own pace. New possible solutions using the
electromechanics of particles may help reverse the contamination to the environment.

What are electromechanical devices?

Electromechanics combines the electromagnetic sciences of electrical engineering and mechanics.

Countless everyday products rely on these systems, from electrically powered windows and vehicles to your
washing and drying machines.

Examples of common electromechanical devices

It is virtually impossible to list every single electromechanical device. You most likely use this equipment every
day, both personally and professionally. Some of the most common devices are used in:
 household appliances such as dishwashers, refrigerators or vacuum cleaners
 transportation, such as trains and trams
 the automobile industry, with alternators and electric motors
 CD and DVD players, printers
 motors and other hydraulic presses

How do electromechanical devices work?

To better understand electromechanics, let’s look at how 3 of the most commonly used systems operate:

1. Electric motors
Electric motors essentially convert electrical energy into mechanical energy using a system of gears and
magnetic fields. Electrical systems can be powered by a variety of direct and alternate current sources, including
batteries, rectifiers, power grids, inverters and electric generators. Everyday products that use electric motors
include fans, blenders and power window regulators.

2. Solenoids
A solenoid is a cylindrical object that generates a magnetic field when a current flows through its wire to create
linear motion. It can also be used as an inductor, instead of an electromagnet, to impede changes in electric
current. A solenoid consists of a coil of corkscrew-shaped wire wrapped around a piston that is typically made
of iron. Solenoids use magnets, which can be turned on and off using a computer or by removing the current.
This makes them particularly useful as switches or valves, found in common products like car keys, doorbells
and a variety of automated industrial systems.

3. Mechatronics
Mechatronics is a field that combines mechanical, electrical, automation and computer science systems. It is
often viewed as the future of automated manufacturing. Those who work at the intersection of these disciplines
may also have extensive knowledge of robotics, electronics, and telecommunications. Mechatronics engineers
aim to create simpler, yet more powerful and intelligent systems. Many products that were once purely
mechanical now rely on mechatronics, including automotive systems like anti-lock brakes, and consumer items
such as digital SLR cameras. These types of systems represent the future of the electromechanical field.

Technological advances and the future of electromechanics

Many jobs that were once done by humans are now done by machines thanks to technological advances in
automation and machine learning. But we still need humans with mechanical knowledge to install, maintain and
repair these machines. Working as an electromechanical technician requires technical skills to assemble and
disassemble equipment according to manufacturers’ specifications.
