1、 Performance and advantages:

1. The deformation of the electric spindle is small. The motor rotor is a rare earth permanent magnet structure, with no excitation current, low rotor heating, and good axial stability of the electric spindle. The machining accuracy of the workpiece is high.

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

3. The surface smoothness of the workpiece is greatly improved. This motor has good speed hardness characteristics and high speed stability under load fluctuations, which can significantly improve the surface smoothness of the workpiece.

4. The rear direct drive structure design and power configuration 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 electric spindle. The structure is flexible and can meet various applications where the radial space of the electric spindle is limited.

5. High power and high torque. Electric 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 the motor can be one level higher under the same volume; Even at the same power, the torque of the rotor is significantly larger because it does not require excitation current.

6. Wide speed regulation range. High speed motors can achieve a wide range of speed regulation, with stepless speed control between zero speed and maximum speed; The constant power ratio of the motor is 1: 1.25.

7. 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 low-speed large cutting amount hard metal cutting and high-speed small cutting amount precision cutting, greatly improving production efficiency.

8. Strong servo performance. Through a special driver program, all functions of the digital servo electric spindle can be achieved.

9. Energy saving. Under the same power conditions, the energy-saving effect is 20% to 50% higher than that of asynchronous electric spindle motors. The higher the power, the more significant the energy-saving effect.

10. Widely used. Due to the addition of low-speed characteristics in the product, the operating speed range has significantly increased and can be serialized. Not only can it be equipped with new equipment, but it is also more suitable for the renovation of old grinding machines. This structure can be used from 500W to 150kW, greatly expanding its application range.

2、 Product usage: Carving and milling machine, drilling and tapping machine, woodworking carving and milling machine.

3、 Packaging: Wooden crate, moisture-proof and shockproof.
