Technical Drawing
Areas of application
Neodymium ring magnets are made of the powerful neodymium-iron-boron (NdFeB) alloy and offer exceptionally high holding force compared to conventional ferrite or AlNiCo magnets. The combination of impressive magnetization capability and high flux density makes neodymium one of the strongest magnetic materials on the market. These properties provide optimal conditions for applications where high magnetic force is required in the smallest of spaces:
- Sound technology and electronics: Neodymium ring magnets are indispensable in electrical engineering because they generate strong magnetic fields in a small space. In loudspeakers and headphones, they use their high magnetic density to move the membranes precisely, which improves sound quality and energy efficiency. They work in a similar way in microphones, where they convert the vibrations of the membrane into electrical signals. In sensors, ring magnets are crucial for detecting motion or position, for example in rotary encoders.
- Mechanical engineering: Neodymium ring magnets are widely used in mechanical engineering, especially in magnetic couplings that are used for contactless power transmission. These are particularly important in pump systems that convey liquids or gases without the need for a mechanical seal. This ensures a longer service life and greater leak-tightness. They are also used to fix and position tools or workpieces in machines. Their precision and strength facilitate assembly and manufacturing processes, for example by holding metal parts firmly without the need for mechanical holders. They are also used in magnetic bearings to minimize friction and wear in rotating systems.
- Automotive industry: In the automotive industry, neodymium ring magnets are an integral part of modern vehicle technology. They are used in various sensors, for example to detect speed (ABS systems) or to monitor the steering. In hybrid and electric vehicles, they are used in electric motors, where they provide high power density. Actuators used in door locks, window regulators, or tailgate controls utilize the precision and power of these magnets. The ability to generate strong magnetic fields in a small space makes them particularly valuable for reducing the weight and space requirements of vehicle components.
- Medical technology: Neodymium ring magnets are used in medical technology because of their precision and reliability. In MRI (magnetic resonance imaging) systems, they help to generate the stable magnetic fields essential for high-resolution images. For prostheses or implanted devices such as hearing aids, they are used to enable magnetic closures or mounts that provide ease of use. The use of such magnets helps to make medical devices smaller and more efficient without sacrificing functionality.
