Neodymium Radially Magnetised Ring Magnets,NdFeB Radial Ring Magnets, uni-pole radial oriented ring magnet

Neodymium ‘Radially Magnetised’ Ring Magnets have a specific magnetic pattern on either their inside or outside diameter and are most commonly available in three different configurations. Magnets with Skewed Magnetisation are used in both servo and power steering motors. Magnets with Multi-pole magnetisation on the Outer Diameter and/or Inner Diameter can be found in servo motors, spindle motors, generators, couplings, and stepping motors. And lastly, magnets with a north pole on the Outer Diameter and south pole on the Inner Diameter, are used in linear actuators, compressors, magnetic bearings and high end speakers.

MPCO is capable of supplying neodymium radially oriented ring magnets based on sintered, bonded and hot-pressed magnets. Compared with conventional arc/segment magnets, these ring magnets have several critical advantages:
• Assembly and installation become much easier, far more efficient and less cost.
• Simpler and more stable structure guarantees better dynamic balance performance.
• More uniform magnetic properties and magnetization waves distribution contribute to less motor noise and smother torque output.

Features of NdFeB Radial Ring Magnets
1. High dimensional accuracy,
2. Optional magnetization patterns including single pole, straight and skew multi-pole types,
3. A single ring magnet makes assembly and installation simple and low cost,
4. Simple and stable structure guarantees excellent dynamic balance performance, and
5. Uniform magnetic properties and magnetization waves distribution contribute to low motor noise and smooth torque output.

Applications of NdFeB Radial Ring Magnets
1. Servo motors,
2. Spindle motors,
3. Electrical power steering motors, and
4. DC motors, etc.
