Micro-electric motor brush life expectancy shorter than the large-scale electrical machinery, but the use of household appliances is shorter, therefore, a group generally can use the brush a few years in the life of electrical brush need to be replaced during the examples of many .
Material from the brush of a general can select a low friction coefficient and contact voltage drop of larger graphite electric brush, resin binder for the high resistance of natural graphite brush can be used for the poor motor. In addition, more abrasive strong carbon-graphite brush is mainly used mica sudden ultra-small motor.

About Sintered Neodymium Magnet
Since the foundation of our company in 2005, we have been engaged in the manufacturing and distributing of magnetic materials. At present, we are capable of producing 220 tons of NdFeB per year and our annual sales rises to 6 million dollars. Our products are mainly exported to Europe, America and Southeast Asia. Half of our products are purchased by American or German loudspeaker manufacturers, such as the JBL and AR in the US as well as the Heco in Germany. Thirty percent are sold to electric machine manufacturers like the Italian Cear and the Chinese Baolai. We have earned good reputation in this industry and established long-term cooperative relationship with multiple clients.
Our product features high quality-price ratio. With superior mechanical properties, it is easy to cut and process. The defects of the sintered neodymium magnet lie in the low Curie temperature, poor temperature characteristics, and high susceptibility to pulverization. We have provided solutions to remedy those flaws by adjusting the chemical composition and electroplating the surface. The product we offer can pass the 72-hour salt spray test and its maximum operating temperature reaches 240ºC, thus satisfying the practical application requirements.
Our sintered neodymium magnet has been widely used for the cell phone headsets, high-end loudspeaker boxes, permanent magnet motors, micro motors, gift boxes, handbags, toys, medical instrumentations, instruments and apparatus, metal and plastic products, electronic components, electric car motors, wind turbine generators, and many other items.
