The principle behind the transformation of electrical energy into mechanical energy is one of the foundations of engineering. This process underlies the functioning of many devices we use daily, including induction appliances, stereo speakers, electric cars, hard drives, drills, air conditioning systems—and, in our case, electrical enclosure fans.
The magnetic field and energy transformation
But how is electrical energy concretely converted into mechanical energy? The answer lies in the generation of a magnetic field. When an electrical current flows through a conductive wire, a magnetic field is generated around it. This is the basic operating principle of electric motors.
Electric motors, which are at the core of devices like fans, harness this magnetic field to convert electrical energy into rotary motion. In particular, in both direct current (DC) and alternating current (AC) motors, the field generated by the motor coils interacts with permanent magnets or other coils, creating a rotational force that moves a motor shaft. This force is known as the Lorentz force.
How electric motors work
An electric motor is mainly composed of two parts: the stator, the fixed part of the motor, and the rotor, the part that moves. When an electric current passes through the stator coils, a magnetic field is generated and interacts with the rotor, causing it to move. The direction of the movement depends on the orientation of the magnetic field and the polarity of the electrical current.
What’s the difference? In alternating current (AC) motors, the magnetic field continuously changes direction, allowing the rotor to spin constantly. In direct current (DC) motors, on the other hand, the magnetic field has a fixed direction, but thanks to a commutator that periodically reverses the electric current, the rotor can keep turning.
Esmeris Frame Fans from Fandis: efficiency and reliability
The transformation of electrical energy into mechanical energy through the magnetic field is a key principle applied in many sectors, including temperature regulation in electrical enclosures. Compact fans, such as those from Fandis’ Esmeris range, are an excellent example of the application of this process. This energy transformation enables the efficient cooling of electronic components, preventing overheating that could compromise the proper functioning of the entire system.
Thanks to advanced electrical protection solutions and motors that maximize energy efficiency, Esmeris fans offer high performance and long operational life—the perfect solution for those seeking reliability and technology, even in demanding or special operating conditions.
