Because of high remanence, high coercivity and high magnetic energy product, neodymium magnets are widely used for servo motor, stepper motor, linear motor, etc.
For the quality of the electric motor magnet,We focus on the following ten point:1)Dimension;2)Appearance ; 3)Magnetic moment; 4)Demagnetization curve; 5)Irreversible loss ; 6)Corrosion; 7)Mechanical property; 8)Glue ;9)Subassembly;10)Packing.
Most customers require neodymium motor magnets with high maximum working temperature, such as 35SH, 38SH, 35EH, 35UH, use some small arc magnets to form a ring magnet, magnetization direction is through diameter, NS and SN. And some require other shapes such as segment, wedge shape, block, ring, or special shape.
