1200 Alnico Magnet Assemblies
Magnets and Magnetic Assemblies are a key component in many industrial sensing applications. Typical Magnetic Sensor applications include contact-less current sensing, linear and angular position, and rotation sensing.
The Magnetic Assembly
The Bunting engineering team designed the bespoke magnetic assembly for a specific customer application. The magnetic assembly consists of:
- Alnico ring magnet;
- Steel core;
The Alnico ring magnet is designed to have a tight fit around the steel core. Once assembled, the magnetic assembly is magnetised using a Bunting designed magnetiser. The finished magnetic assembly has four magnetic poles.
The magnetic assembly used Alnico magnets due to the ability to maintain a magnetic field at high temperatures. Other magnet materials, such as Neodymium, would significantly lose magnetic performance with rising temperatures.
This particular order was for 1200 Alnico magnetic assemblies.
Magnetic Sensors are used in a wide variety of applications including:
- Power Distribution Units in data centres and servers (linear and angular sensing, safety switches and proximity detection);
- Robotics and Factory Automation (liner and angular sensing are key for the complex motor movements and are also used in safety switches and proximity detection);
- White Goods (open/close door detection, fluid levels and contactless current sensing in cookers, washing machines, vacuum cleaners and refrigerators)
- Green Energy (contactless current sensing, angular position sensing and switches in both wind and solar power generation);
