Radial Oriented Neodymium Rings
Radially oriented neodymium ring magnets are the perfect solution for high-performance permanent magnet motors and sensors that require precise and stable operation. While more costly to manufacture than traditional neodymium magnets, radial oriented ring magnets can reduce the expense of assembling arc segments. Radial oriented ring magnets are also dimensionally superior, reduce cogging and noise in motor applications.
Radially Oriented Ring magnets can be magnetized as unipolar, multi-pole, and skewed magnetization patterns to meet a wide range of application requirements.
Radial Oriented Neodymium Ring Grade Chart
The following is our radial oriented neodymium magnet ring grade chart. We have the capability to formulate any desired grade of magnetic material based on customer specified parameters.
