The permanent magnet synchronous electric spindle can meet the special requirements of low-speed and powerful cutting of CNC machine tools, as well as the special requirements of high-speed precision machining, bringing personalized customization and integrated innovation to customers, optimizing the overall solution. At the same time, due to its small moment of inertia, fast acceleration and deceleration, higher work efficiency, low rotor temperature rise, stable and accurate operation, higher surface machining accuracy of the workpiece, wide speed range, and small torque fluctuations, this process has a wide range of applications.

The excellent magnetic field synchronization of rare earth permanent magnet synchronous electric spindle and spindle motor, combined with special servo drives and optimized control schemes, can increase machining efficiency by more than twice compared to mainstream small vertical machining centers and drilling and milling centers in the domestic market. The vertical machining center and drilling and milling center using rare earth permanent magnet synchronous electric spindle and rare earth permanent magnet synchronous high-speed liquid cooled spindle motor integrate the drilling and milling center with the engraving and milling machine, becoming a high-speed and efficient application solution that integrates milling, engraving, tapping, grinding, drilling, boring, sinking, reaming, and expanding processes.

The transmission error is small, the length of the main transmission chain of the machine tool is zero, and the motor directly drives the spindle without any transmission error. The spindle vibration is significantly reduced, and the surface smoothness of the workpiece is significantly improved;

High power ratio, wide constant torque range, and fast response speed. The motor is a rare earth permanent magnet synchronous motor with high power density and torque density;

Compared with asynchronous motors, it has a high response speed, high motor power density, wide constant torque range, and is one power level higher than asynchronous motors of the same volume;

Built in direct drive structure design, flexible power configuration. The motor is located inside the spindle, and its power can be matched with the thickness and length of the spindle at will. Therefore, the structure is very flexible and can meet various applications where the radial space of the spindle is limited;

Wide speed regulation range, the motor can achieve a wide speed regulation range, and stepless speed regulation can be achieved from zero speed to maximum speed;

High productivity, the motor has excellent low-speed hard characteristics. With the allowance of bearing stiffness and tool hardness, it can perform precision cutting of hard metal, low-speed cutting with large cutting amounts, and high-speed cutting with small cutting amounts, greatly improving production efficiency.

Strong servo performance, combined with dedicated drivers, can achieve all functions of digital servo spindles, such as rigid tapping, accurate positioning, etc. Choosing to cooperate with high-precision encoders can achieve CS, CF functions, etc.
