Super Strong Rare Earth Motor Magnet

This neodymium motor  parts are composed by strong magnets and steel plates.The neodymium  motor parts are with nickel surface heavy treatment which prevent corrosion. These neodymium magnets could be used at high temperatures. The Motor magnets are commonly referred to arc shaped magnets with constant magnetic powers. Motor magnets are generally used in AC and DC brush/brushless motors,stepping motors, servo motors and other motors, the motor magnets have been extensively applying in modern industry, military industry,and aviation industry.

Main Manufacturing Process

Melting: In the melting furnance,the neodymium,iron,boron materals form as compund ingots.

Hydrogen demolish: Shatter the ndfeb ingots into ndfeb powders.

Airflow mill:The ndfeb powders will be milled into micron sizes.

Shaping: Ndfeb powders in the mold will be pressed as ndfeb ingot.

Isostatic Pressing: Bearing the isostatic pressure is a important process to enhance the magnetism and of ndfeb material.

Sintering:The sintering procedure, were processed in a sintering furnace under 800~1300 ℃ vacuum environments.

Cutting: After the slice cutting process,the sizes of magnets will become suitable rectangles.

Grind and polish:Neodymium magnets had been ground before they were magnetized.We could produce magnets with standard tolerances for magnets from the range +/-0.07, +/-0.05, +/-0.03, +/-0.02,and 0.01

Plating: Neodymium magnets had been treated with electrical plating,otherwise it will rust in the air. Platings that have been successfully applied to neodymium magnets are epoxy plating,nickel plating,NICUNI plating,zinc palting.

Megnetization: Cylinder magnets are magnetized from the axial direction.
