what's arc segment magnet(SmCo, NdFeB, ferrit)? where's neodymium arc magnets manufacturer? how to buy samarium cobalt segments or ferrit motor magnets?

motor arc magnets for automobile industry is our important product, according to the automobile features, we research and design a series magnet to meet the demand, among the magnet for starter motor and window-rolling motors are the leading magnet in China. In addition, you also could choose other excellent magnet for your industry, including magnet for electric tools, magnet for medical & health care appliance, magnet for general dynamo & standard motors, and magnet for other DC motors ect.

Generally speaking, arc magnet are all made as customer design and as Special requirement. our factory produce and manufacture magnet according to customer design on shape, dimension, grades, coatings etc. Motor magnets are most in arc or segment shape. some are block magnets. arc magnets is one special shape of rare earth magnets. It is always manufactured via wire cutting and grinding etc. regular arc magnets or regment magnets have the following important factors such as: outer diameter or outer radius, inner diameter or inner radius, degree of angle, thickness, length ,round edge etc

neodymium arc segment magnets

NdFeB Arc Magnet or NdFeB Segment Magnet is one of the high performance rare earth permanent magnets, which use neodymium (Nd), iron (Fe), and boron (B) as their main ingredients and is susceptible to demagnetization when exposed to elevated temperatures.

There are many grades which can withstand high temperatures, but several factors will dictate the performance of the Neodymium magnet. There are Sintered NdFeB, Sintered AlNiCo, Sintered SmCo and Sintered Ferrite.

Since the Neodymium Iron Boron magnets are prone to rapid oxidation, salt spray, salt water, and hydrogen are very harsh on the magnet. Consider hermetically sealing the magnet if you wish to use NdFeB in such environments. For high reliability applications, familiarize yourself with the section "testing and certification" so that you understand the tests that are available. Some of these tests are used to predict how the magnet will perform over extended periods in the field.
