In a rare earth permanent magnet DC motor speed on the application

Energy access and application of the progress of human society is an important symbol of the power of modern society can not leave an energy form, in any industry in the field of electric energy applications are very wide-ranging. The power of the most common form, is the electrical energy into mechanical energy, by means of conversion is relying on motor applications. Electric motor to convert mechanical energy is good or bad, and on whether to make full use of electricity, driven by the relationship between the efficiency and functioning of the equipment, people have been constantly developed to meet the requirements of the motor. Recalling the development of motors, DC motors from the motor people have to exchange for the motor progress and work hard. Until the emergence of Nd-Fe-B permanent magnet, people began producing rare earth permanent magnet motor obtain the support of the advanced materials, but to the related industrial products improved and the mechanical and electrical integration to the updated level.

Rare earth permanent magnet brushless DC motor speed of modern materials science, electronics and electrical power control science and the result of combining theory. Rare earth permanent magnet motor is to use rare-earth permanent magnetic materials have magnetic field, instead of the traditional motor excitation current generated by the magnetic field, making a rare earth permanent magnet motor structure is simple, reliable operation, small size, light weight, low loss, high efficiency motors, type and size can be flexible, and other notable features, rare earth permanent magnet motor rapid development in recent years. Since China's rare earth rich in natural resources, rare earth permanent magnet, the rapid development in the country, making rare earth permanent magnet material continuously improve product quality, reduce cost prices, greater power for the manufacture of rare earth permanent magnet motor laid a solid foundation, and has enabled us to develop The rare earth permanent magnet motor in the domestic and international market will have a certain competitive advantage.
