The high-speed electric spindle is the core component of the high-speed machine tool. It combines the machine tool spindle and the motor shaft into one, that is, the stator and rotor of the spindle motor are directly loaded into the spindle assembly. It has the advantages of compact structure, light weight, small inertia, good dynamic characteristics, etc., and improves the dynamic balance of the machine tool, avoids vibration and noise, and has been widely used in ultra-high-speed machine tools.

High power density frameless motors are considered to be the first choice for advanced collaborative robot joint motors. By designing the joint motor rotor with silicon-free steel sheets, the joint motor can achieve low weight, high power density, and high-precision control, which cannot be achieved by joint motors of industrial robots. attainable advantages.
