Sintered multi-pole ring is a new type of ring magnet, produced by special technology. By this technology, surface magnetic flux can reach top level, about 50%-100% higher than the arc magnets and radial ring magnets. The surface flux is distributed by sine wave shape. Because of its high surface gauss, it can remarkably raise the efficiency of motors efficiency, and it also helps motor to be light-weight and save raw materials.These make it to be a good choice for high-performance motors. multi-pole radial magnetic ring for sensor
Advantage：
1-Higher flux density
2-Rotor shaft can be non-magnetic material, to reduce weight of motor without reducing magnet performance
3-Higher utilization of Permanent magnet
Sintered NdFeB Radial Oriented Ring Introduction：
Radial ring is whole radial oriented ring magnet, it can be magnetized as multi-pole, skewed and uni-pole magnetized. The ring mainly used as induction magnet for motors. It can improve the motors’ performance and property. It is the future development tendency of motor magnets. MPCO is one of the best sintered NdFeB ring magnet manufacturer in China.
Advantage：
● Assembling easier.
● Mechanical precision better.
● Stable magnetic property.
● Improve the motor performance.
