At Bobinados Osés, we manufacture electromagnetic brake coil solutions specifically developed for OEMs and industrial manufacturers that require custom electromagnetic components.
For almost 40 years, we have developed components adapted to the specific requirements of each project, from prototypes to production series. We do not work with standard catalogue products or operate as a distributor: we design, manufacture and assemble each solution according to customer drawings and specifications to ensure optimal integration into the final equipment.
As an experienced electrobrake coil manufacturer, we regularly work with design engineers, purchasing managers and industrial integrators looking for a reliable supplier with series production capabilities and technical support throughout the project lifecycle.
If you need a specific solution, our technical team can analyse your requirements and recommend the most suitable approach for your application.

What is an electromagnetic brake coil?
An electromagnetic brake coil converts electrical energy into magnetic force to activate or release a braking system. Although its operating principle is relatively simple, the coil plays an essential role in ensuring safety, stopping accuracy and operational continuity in industrial equipment.
These coils are directly involved in motion control. Optimised electromagnetic design, effective thermal management and precise manufacturing are therefore essential to prevent failures, minimise maintenance requirements and extend the service life of the braking system.
Negative electromagnetic brakes (safety brakes)
Negative electromagnetic brakes remain engaged when no electrical power is supplied. When the coil is energised, the braking system releases and allows movement.
They are commonly used in:
- Lifts
- Goods lifts
- Electric pallet trucks
- Industrial cranes
- Wind turbines
Their main advantage is automatic braking in the event of a power failure. This makes them particularly important in applications where operational safety is a priority.
Positive electromagnetic brakes (active brakes)
Positive electromagnetic brakes generate the braking action when electrical current is supplied.
They are commonly used in:
- Servomotors
- Industrial spindles
- Positioning systems
- Automated conveyors
Their operating principle enables precise motion control and fast response in industrial automation processes.
| Feature | Negative electromagnetic brake | Positive electromagnetic brake |
|---|---|---|
| Activation | Without electrical power | With electrical power |
| Brake release | When the coil is energised | When power is removed |
| Behaviour in case of power failure | Automatic braking | Depends on the system |
| Typical applications | Lifts, goods lifts, pallet trucks | Servomotors, automation |
| Main objective | Safety | Control precision |
Custom electromagnetic brake coil manufacturing
As an electrobrake coil manufacturer, we develop each project according to the customer's technical specifications. Instead of adapting the application to a standard product, we manufacture the component according to the actual requirements of the equipment.
We can adapt parameters such as:
- Voltage
- Current
- Duty cycle
- Available dimensions
- Connection type
- Encapsulation
- Required thermal class
Our experience as an OEM coil supplier allows us to become involved from the early stages of development. This helps optimise system performance, reduce potential issues and facilitate component integration into the final product.
Each electromagnetic brake coil can be developed for demanding industrial environments and applications involving high operating cycles.
This custom approach is particularly valuable for OEM manufacturers that require repeatable performance and a component specifically adapted to their mechanical, electrical and production requirements.
Electromagnetic brake coil design for industrial applications
The performance of an electromagnetic brake coil depends on multiple electrical, magnetic, thermal and mechanical variables. For this reason, we analyse every project individually.
Factors such as nominal voltage, electrical resistance, generated magnetic force, switching frequency and thermal dissipation have a direct impact on the reliability of the complete system.
We carefully select conductive materials, insulation systems and manufacturing processes to develop industrial brake coils capable of maintaining stable performance even in critical applications.
This engineering approach enables us to:
- Optimise electromagnetic performance
- Improve thermal management
- Reduce the risk of premature failures
- Increase component durability
- Maintain stable operation under demanding conditions
As an electrobrake coil manufacturer, our role goes beyond manufacturing a winding. We develop components according to the actual operating conditions and technical requirements of the customer's equipment.
Complete electromechanical subassemblies
One of our main advantages as an electrobrake coil manufacturer is our ability to supply fully assembled electromechanical subassemblies.
We do not only manufacture the coil. Depending on the requirements of the project, we can integrate:
- Magnetic cores
- Housings
- Springs
- Wiring
- Connectors
- Soldered components
- Riveted components
- Laser marking
This allows our customers to reduce assembly times, minimise assembly errors and simplify supplier management.
As an OEM coil supplier, we deliver assemblies ready for integration into production, with traceability and quality control throughout the manufacturing process.
We can also incorporate laser marking and RFID technologies to facilitate component identification and traceability.
For manufacturers requiring more than an individual electromagnetic brake coil, this capability makes it possible to receive a complete electromechanical solution ready for integration into the final equipment.
Electrobrake coil manufacturer for OEM projects
We work with OEMs, integrators, engineering companies and industrial manufacturers that require reliable electromagnetic solutions developed according to specific technical requirements.
Choosing an electrobrake coil manufacturer with industrial production capabilities is particularly important when a project requires consistent quality from the prototype stage through to series production.
Our experience in industrial winding manufacturing allows us to collaborate on projects with demanding technical and production requirements.
We actively participate in:
- Technical validation
- OEM manufacturing
- Industrialisation
- Series production
Bobinados Osés is focused exclusively on the industrial market. We work closely with technical departments, engineers, purchasing managers and production teams to develop efficient solutions designed for continuous manufacturing.
As an electrobrake coil manufacturer, we can therefore support the different stages of an OEM project rather than simply supplying a standard catalogue component.

Medical equipment
We manufacture custom solutions for equipment where reliability, repeatability and quality control are essential.
Our production capabilities allow us to adapt each electromagnetic component to the technical and manufacturing requirements of the final application.
Electromagnetic brake coil manufacturing with ISO 9001 traceability
Copper coils for electromagnetic braking systems form part of our broader manufacturing capabilities, which include solenoids, electromagnets and complete electromechanical assemblies.
We operate under processes certified according to ISO 9001:2015 to ensure quality, repeatability and control throughout each project.
Every electromagnetic brake coil is developed following validation procedures designed to ensure consistent performance and long-term reliability.
As an electrobrake coil manufacturer, we have the capability to develop custom projects from the initial design and prototyping stages through to industrialisation and series production.
This complete approach allows OEM manufacturers to combine technical development, industrial manufacturing, quality control and electromechanical assembly with a single specialised supplier.
Frequently asked questions about electromagnetic brake coils
Why does an electromagnetic brake coil overheat?
An electromagnetic brake coil can overheat due to overvoltage, incorrect power supply, insufficient cooling or duty cycles exceeding its design specifications. Ambient temperature and an unsuitable thermal class can also affect its service life.
What is the difference between a negative and a positive electromagnetic brake?
A negative electromagnetic brake engages when electrical power is removed, making it suitable for safety applications. A positive brake requires electrical power to generate the braking action.
Can electromagnetic brake coils be designed for high switching frequencies?
Yes. Electromagnetic brake coils can be designed for high switching frequencies by considering heat generation, response time, duty cycle and operating conditions during the development process.
