Arc magnets are mainly used in permanent magnet DC motors. Unlike electromagnetic motors that generate magnetic potential sources through excitation coils, PM motors use permanent magnet materials to generate constant magnetic potential sources. Instead of electric excitation, permanent arc magnets have many advantages, which can make the motor simple in structure, convenient in maintenance, light in weight, small in size, reliable in use, low in copper consumption, and low in energy consumption.
Standard Neodymium Magnets
Neodymium magnets (also known as Nd-Fe-B) is one type of rare-earth permanent magnet. And it is an important component for electric vehicles, house appliances, robots, garden tools, medical equipment, etc.
AH Magnet is specialized in researching, developing, manufacturing and exporting high-performance sintered neodymium iron boron magnets, 47 grades of standard neodymium magnets, from N33 to 35AH, and GBD Series from 48SH to 45AH are available. All magnets are widely applied to electric motors such as servo motors, stepper motors, brushless motor, linear motors, permanent magnet synchronous motors, etc.
Aim to increase the corrosion resistance of sintered neodymium iron boron magnets and to meet the designated surface requirements, we provide the normal coating layers, like nickel-coating, zinc-coating, epoxy-coating, aluminum-coating and passivation. We also customized composite coating to ensure durability of magnets according to different design and application environment of permanent magnets.
