Motor Magnet
Material: Neodymium(ndfeb)
Coating:Nickel
size:according to your needs
certification:SGS,ISO9001,ROHS

Motor Magnet mainly comprised of neodymium ,iron and boron,is the third generation of the rare-earth permanent magnets,Sintered Ndfeb is the strongest permanent magnets in the world up to date,It has excellent properties of high remanence,coercivity,and Max.energy product.

 Motor Magnetgrade:

N35,N38,N40,N42,N45,N48,N50,N52(Max.operational temperature: 80c)

N33SH,N35SH,N38SH,N40SH,N42SH(Max.operational temperature:150c)

N28UH,N30UH,N33UH,N35UH,N38UH(Max.operational temperature:up to 180c)

N28EH,N30EH,N33EH,N35EH(Max.operational temperature:up to 200c)

N30AH,N33AH,N35AH(Max.operational temperature:up to 230c)

Motor Magnet Temperature:

Temperature sensitivity varies, but when a magnet is heated to a temperature known as the Curie point, it loses all of its magnetism, even after cooling below that temperature. The magnets can often be remagnetized however. Additionally some magnets are brittle and can fracture at high temperatures.

Motor Magnet Outsanding product:

1)high performance:N52,N48M,48SH,42UH,38EH,33AH

2)high working temperature:the AH series with 40 k Oe super-high coervice force can replace SmCo magnets successfully.

3)high consistency:the cpk of Br and Hcj are much higher than 1.67 the consisitency of surface magnetic field and magnetic flux can be controlled with +/-1%

4)High Anti-corrosion:the sale spray test and humid heat test of the high anti-corrosion coating could be more than 1000 hours

5) low weight loss

PCT:130c ,humidity 100%,vapor pressure 2.7 bar.20 days,average low weight loss less than 2 mg/cm2

Motor Magnet applications:

loudspeakers,motor assemblies,windmill,Home appliance,acousics,communication equipment,toy,car,servomotor,step motor,DC motor and linear motor,mircrophones

Pros: Very strong hold when contacting another magnet or plain iron, very difficult to pull away (easy to slide however).
Pretty strong hold between two of these even with a couple of mm in between.

Cons: Would like thicker (and more powerful) versions. Sure u can stack these together but sometimes it's not the same thing.

Other Thoughts: Good for attaching thick stacks of paper to refrigerators etc or pinching together papers or textiles.

Bottomline: This is the one if you need strong cost-effective magnets
