1High end electric spindleThe surface smoothness of the workpiece is greatly improved, and the motor has good rotational speed hardness characteristics. It has high rotational speed stability under load fluctuations, which significantly improves the surface smoothness of the workpiece.

2. The transmission error of high-end electric spindles is small, the length of the machine tool's main transmission chain is zero, 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.

3. High end electric spindles have high power and torque. The motor is a rare earth permanent magnet synchronous motor with high power density and torque density. Compared with asynchronous motors, the power and torque of this type of motor can be one level higher in the same volume; Even at the same power, due to the fact that the rotor does not require excitation current, its torque is significantly larger.

4. High productivity. This motor has good low-speed hard characteristics and can be used for rigid tapping. Under the conditions of bearing stiffness and tool hardness, it can be used for hard metal, low-speed large cutting volume cutting, and high-speed small cutting volume precision cutting, greatly improving production efficiency.

5. The rear direct drive structure design and power configuration of high-end electric spindles are flexible. The motor is located at the rear end of the electric spindle, and its power can be matched with the thickness and length of the spindle at will. The structure is more flexible and can meet various applications where the radial space of the spindle is limited.

6. The high-end electric spindle has a wide speed range, and the motor can achieve a wide speed range, with stepless speed regulation between zero speed and maximum speed; The constant power ratio of this motor is 1:1.25.

7. The high-end electric spindle has strong servo performance, and through a dedicated driver program, all functions of the digital servo spindle can be achieved.

8. The high-end electric spindle has small spindle deformation, the motor rotor is a rare earth permanent magnet structure, no excitation current, low rotor heat generation, and good axial stability of the spindle; The machining accuracy of the workpiece is high.

9. The application range of high-end electric spindles is wide; Due to the addition of low-speed characteristics, the working speed range of the product has significantly increased and can be serialized. It can not only be equipped with new equipment, but also more suitable for the transformation of old grinding machines. This structure can be used from 500W to 150kW, greatly expanding its application range.

10. Energy saving of high-end electric spindles: Under the same power conditions, the energy-saving effect is 20%~50% higher than that of asynchronous spindle motors, and the higher the power, the more significant the energy-saving effect.
