The Deko® Radiation ring NdFeB magnet are produced in two method, one is normal radial orient pressed magnets, another is new technique- hot press radial magnets. In rotor of motor, here we mostly need a radiation ring that magnetized it into 4/8/10/12/18/20 poles, to get a big flux field. Sometimes we use a flat 4/8 poles magnetized ring, it’s economic choice, for those consumer market.
Radiation Ring NdFeB Magnet is used in below area:
The Deko® Radial oriented ring NdFeB magnets from China factory are produced in two method, one is normal radial orient pressed magnets, another is new technique- hot press radial magnets. In rotor of motor, here we mostly need a radiation ring that magnetized it into 4/8/10/12/18/20 poles, to get a big flux field. Sometimes we use a flat 4/8 poles magnetized ring, it’s economic choice, for those consumer market.
Usually these magnets are N38M,N38H,N42H,N35SH,N38SH,N40SH.
Typical size is D30xd20x10 mm;
When the motor speed is over 100,000 rpm, we suggest you use a hot pressed ring magnet, it’s good mechanical property and stable output.
The coatings we can supply are very wide, Zn, Ni, NiCuNi, chemical Ni, NiSn, epoxy, PTFE, Everlube, MoS2, different coating support your magnets work stable in different environment, we have some solutions for those difficult situation, as wet, hot, moisture, acid, etc.
