Rotor NdFeB magnet is used in below area:
The Deko® Rotor NdFeB magnet which you can customize is used in electric motors, like servo motors. It saves size of motors, and supply a strong power.
Usually these magnets are N38M,N38H,N42H,N35SH,N38SH,N40SH,N35UH,N38UH.
When the motor speed is over 20,000 rpm, we suggest you use a phosphating coating or everlube/epoxy coating, it’s good binding force with magnets to avoid fall off.
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.
