Specifications
Magnetic rotors which are made by plastic injection outside NdFeB magnets or ferrites in can, high in efficiency and working with low noise. They are widely applied in cars, water pumps, disk drivers, starting motors of motor bikes and stepping motors etc.
Materials
Permanent segment ferrite magnet is made of SrO.6Fe2O3 and other microelements by ceramic processing.
Strontium ferrite powders have been designed to produce all grades of hard ferrites.High quality products are made by adding proper additives into the powders. And strict quality control system ensure the quality is stable and reliable.
Arc magnets are also widely applicable to other D.C. motors, such as power antennas, fuel pump motors, rear windshield wipe motors, power curtains, blower motors for air-purifiers, power seat motor lumbar support, power seat motor-side support, power seat motors, power window regulator motors, electric sunroof regulator motors, blower motors, front windshield wipe motors, height adjusting motors, stepping motors, motors for ABS, condenser cooling fan motors, radiator cooling fan motors and starter motors.
We are supplier of NDFEB BLOCK MAGNETS,or call Neodymium block magnet, block sintered NdFeB Magnet, which can be used as fan generator magnets .
1.NdFeB magnet is The strongest power magnets in all of the permanent magnets. Which can be made in different shape, such as Block sintered NdFeB magnet, Disc sintered NdFeB magnet, etc.
2.Material:Sintered Neodymium-Iron-Boron;
3. The material Grade including: N35 to N52;N35M to N50M;N35H to N48H;N35SH to N45SH;N30UH to N40UH,N30EH to N38EH.Also we can suggest the grade according to where the magnets will be used according to our customer's request.
4. Advanced techniques: Utilizes new Sintered NdFeB magnet techniques and equipment such as strip casting, HDDR technology in our factory to allow us to make high performance NdFeB over N52 possible.
5. The Excellent strength value: the highest (BH)max reaches up to 51MGOe.
6. The Extremely Resistance to demagnetization with Hci,the intrinsic coercive force is over 30000Oe.Neodymium magnet loss -0.09~-0.13% on Br/°C;
7. The moderate temperature stability, their working stability is under 80 degree centigrade for low Hci for NdFeB magnet and above 200 degree centigrade for high Hci NdFeB magnet.
8.Various shapes and sizes or according to customers' requirement; Also we can design the size for our customer's request.
