Application of NdFeB Magnets

4 CD-ROM, DVD-ROM industry

With the rapid development of multimedia technology and the large-scale application software trends, the need for high-speed high-capacity storage media to replace the floppy disk. CD-ROM drive is a new type of laser information storage devices. A large capacity, highly reliable, interference and can be used in harsh environments, medium and long life characteristics. 2000 global optical drive market demand reached 106 million Taiwan. At present CD-ROM dominant, but the CD-ROM market will be the impact of DVD-ROM, is expected 2002 sales of DVD-ROM may reach 6 million units. The main supporting the CD-ROM, DVD-ROM micro-DC spindle motor demand will increase dramatically. The motor structure for the rotor, rotor Bonded NdFeB magnets using a forming.

5 Machine Tool Industry

At present, the United States, Europe, industrialized countries, the automobile industry because of the influx of large numbers of production automation, has been fully realized in pursuit of small quantities of more flexible production, the increasing use of NC machine tools. Multinational car industry also flying in this direction. According to preliminary statistics, at present, the world has about 14 million machine Taiwan, which the NC Machine Tool and Machine possession of the ratio is about 7.1%; the world machine tool production is about 150 million units, of which 200,000 NC machine tool output Taiwan, NC Machine share of about 13.3%. According to an average of 2.5 per NC machine coordinates of the system, the coordinates of the 500,000, 80% of permanent magnet DC motor control, and AC motor is unable to meet the requirements of small size, which no doubt opened up a NdFeB Magnets Application of a broad market, in particular the Bonded NdFeB Magnets, NC machine is the ideal Cicai motor. NC machine tools because of the ambient temperature is not high, other conditions good, Bonded NdFeB Magnets thin-walled ring for the axial orientation of magnetization can be multi-polar, both injection molding or compression molding, so that size can be accurate, orientation of the magnetic field uniformity.
