Three Phase High Speed Motors & Spindles
RSH/RSB series High-Speed Motors & Spindles
RSH high-speed motors and RSB high-speed spindles are the three-phase, high-speed induction product line specially designed by our company. Used with frequency converters, they enable the electric shafts to rotate at a high speed, thus achieving a simplified and compact mechanism. High-precision shafting design enables the spindle to operate at a high speed and high precision for precision machining of work pieces with directly installed cutters. RSH/RSB high-speed motors and spindles are extensively applied for purposes as following.
1) High-speed milling, trimming, cutting, drilling and engraving of woods, plastics, glass, rubber and aluminum, etc.
2) High-speed emulsification power or homogenizers for precision medical appliance products, refined chemical products, cosmetics industry and food processing machinery.
3) High-speed drills in precision electronic industry and light industry machinery.
4) High-speed winding main shafts in textile industry.
5) Power of high-speed testers for high-speed rotation test for some products.
6) Other applications that need high-speed operation without mechanical driving mechanisms, such as high-speed pumps or high-speed fan driving applications.
