Elevator Motor Neodymium Magnets

SpecificationsWedge wind generator magnet1. Certification: TS169492. Strong demagnetization3. Grade: N35-N52, M, H, SH, UH, EH. Wedge wind generator magnet1) NdFeB arc or segment magnet has superior magnetic properties than other magnets2) Higher unit magnetic properties3) Smaller size and lighter weight in designing devices4) Mostly an iron based alloy, NdFeB type rare earth magnet is much more prone to surface oxidation or rust, and elimination. Users should consider magnet coating, plating or suitable surface treatment5) Less prone to chipping during handling6) Lower temperature coefficient of magnetic properties than ceramic, higher than SmCo type rare earth magnet7) Irreversible loss at high temperature8) Types: N30, N33, N35, N38, N40, N42, N30M, N33M, N35M, N38M, N40M, N27H, N30H, N33H, N35H, N37H, N27SH, N30SH, N33SH, N35SH, N25UH, N28UH, N30UH, N35SH, N38, N45, N48, and N509) High energy ranging from 8MGOe to 48MGOe with wonderful coercive force10) Less expensive, and mechanically stronger and less brittle than SmCo11) Density: 13%, smaller than SmCo products12) For most applications, coating or plating is recommended13) Advantages: A) High energyB) Very high Hc and Hci outputC) More economical than SmCoD) Wonderful performance at ambient temperatureE)Relatively low cost; F)Poor resistance to corrosion and should have a coating; G)Very high strength; H)Can replace SmCo magnets. 14) Disadvantages: A) Working temperature is below 2, 000^oCB) Prone to oxidation than other magnet alloys15) Widely used in apparatus and instruments where a strong magnetic field is needed, Including motors, sensors, microphones, electro-acoustics, magnetic separation, Magnetic suckers and magnetic therapy
