Use of electromagnets
Efficiency and precision: electromagnets optimise energy and the environment
Electromagnets play a key role in the field of energy and the environment, particularly in the development of efficient and sustainable technologies.
Examples of applications for electromagnets in the energy and environment sector:
- Reversing solenoid for the mechanical actuation of circuit breakers in medium and high-voltage lines
- Linear solenoid for fluid control in power plants or refineries
- Linear solenoids in tracking systems for the alignment of solar panels

Reversible solenoid application example
Medium and high-voltage lines
A reversing solenoid in a technical system for the power supply takes on the task of actuating the switching mechanism precisely and reliably. It converts electrical energy into mechanical movements to open or close the contacts. Thanks to the bi-stable design, the switch remains securely in the open or closed position even in the event of a power failure. This robust, magnetically actuated technology is characterised by minimal moving parts and high corrosion resistance, which enables a long service life and up to 10,000 switching operations without major maintenance.
Technical requirements
How Magnetbau Schramme solves the technical requirements
Electromagnets in the energy and environment sector must fulfil specific technical requirements in order to work reliably in demanding applications. Important features include high efficiency with minimal energy consumption, precise control and fast response times, particularly when switching circuits in wind power or hydrogen production.
Durability and corrosion resistance, for example through galvanic coatings or special insulating materials, are also crucial. Electromagnets must work stably under extreme environmental conditions, whether at high temperatures, humidity or in environments with strong electromagnetic fields.

1. Electromagnet types
Reversing solenoids, switching solenoids, solenoid valves, magnetic bearings and electromagnetic clutches are used in the energy and environment sector. These technologies enable precise control, energy efficiency and reliable performance in wind turbines, hydrogen systems and other sustainable energy applications by providing, for example, fast switching operations, frictionless bearings and powerful coupling systems.
2 Industry-specific technical requirements
In the energy and environment sector, electromagnetic drives must fulfil high requirements in terms of efficiency, reliability and environmental compatibility. The devices must work reliably at high temperatures and humidity and be resistant to corrosion, especially in offshore wind turbines or hydrogen technologies. Legal standards such as IEC 60079 (for explosion-proof designs) set minimum requirements for safety and operation. High precision control is also required, especially in renewable energy systems, in order to minimise energy losses.
Electromagnetic drives must also offer fast response times and a long service life with minimal maintenance, which is ensured by advanced materials and designs.
3. special features
The energy and environment sector differs from others in its particularly high requirements for sustainability and environmental compatibility. Electromagnetic drives must operate reliably in extreme environments such as offshore wind farms or in hydrogen systems, while offering maximum efficiency and minimising energy consumption. Service life and ease of maintenance are also crucial, as downtime is costly in this industry and safety is paramount.
Electromagnets for energy & environment - Questions & Answers
What safety standards apply to electromagnets in energy technology?
Electromagnets in energy technology must fulfil high safety standards in order to avoid failures or dangerous incidents. This includes regulations for EMC (electromagnetic compatibility), IP protection classes for the electronics and regulations for insulation and overload safety. They must also be certified in hazardous areas in accordance with ATEX directives in order to work safely in dangerous environments.
What types of electromagnets are used in energy technology?
Reversing solenoids, switching solenoids and solenoid valves are primarily used in energy technology. Reversing solenoids ensure precise switching operations in electrical circuits, switching solenoids interrupt the energy supply in the event of faults, and solenoid valves control the flow of liquids or gases in energy systems, for example in cooling or pressurised systems.
How are electromagnets used in the energy and environmental sectors?
Electromagnets are used in the energy and environmental sector for precise control tasks, such as opening and closing valves in power plants, sewage treatment plants or geothermal plants. They play an important role in the automation of switching processes in power grids and the optimisation of smart grids. In recycling plants, they enable the mechanical separation of materials and thus contribute to environmental protection.
What demands do extreme environmental conditions place on electromagnets in the energy sector?
Electromagnets in the energy sector have to withstand extreme temperatures, moisture and corrosion, especially in offshore wind turbines or hydrogen storage facilities. They require special coatings and materials in order to remain durable. Their functionality must not be impaired by changing weather conditions and strong electromagnetic fields.
What role do electromagnets play in smart grid systems?
Electromagnets in smart grid systems are used to control switchgear and protective mechanisms. They enable the automatic switching of current flows, quickly isolate defective areas and promote a stable grid frequency. Thanks to fast response times and precise control, they help to increase efficiency and minimise faults in smart grids.
How do electromagnets work in wind turbines?
Electromagnets in wind turbines are mainly used in rotor brakes, pitch systems and magnetic bearings. They control the angle of attack of the rotor blades (pitch) in order to optimise performance or to bring the blades into a safe position if the wind is too strong. Magnetic bearings reduce friction and enable efficient rotation of the nacelle, while magnetic brakes can stop the rotor blade quickly if necessary.
How are electromagnets used in electric vehicles and charging infrastructures?
Electromagnets are used in solenoid valves and induction charging systems in electric vehicles and charging infrastructures. Solenoid valves control the flow of coolants and optimise the performance of batteries. In induction charging, they enable wireless energy transfer, which enables an efficient and convenient charging infrastructure for electric vehicles.
How are electromagnets used in geothermal power plants?
In geothermal power plants, linear solenoids are used to precisely control valves and flaps, e.g. to regulate the flow of hot water or steam from geothermal reservoirs. They enable quick opening and closing of safety valves to prevent overpressure situations and ensure operation. Linear solenoids also control the supply and discharge of working fluids in closed circuits, such as those used in binary power plants. Their reliability and durability make them ideal for continuous use in harsh, hot environments.
