The spindle motor, also called the motor spindle, is an important component of many modern machine tools and industrial robots. Since the motor drives the spindle directly with this spindle drive and there is no gearbox or V-belt for translation, the motor spindle is also referred to as a direct drive.
Spindle is for short of High Frequency Spindle, also referred to as "direct drive spindle" sometimes, which is part of built-in type motor. It shortens the length of main drive chain of machine tools into zero, to achieve "zero transmission" of machine tool, featured compact, high mechanical efficiency, which can perform excellent in high speed rotary, high precision of rotary, low noise, little vibration etc. Therefore, electric spindle have more and more wide application in modern CNC machine tools. In foreign countries, electric spindle has become a high-tech product of mechatronics, produced by professional factories with high technical level, such as Fischer in Switzerland, GMN in Germany, Precise in the United States,Gamfior in Italy, NSK in Japan etc.
Spindle motor is usually also called high-speed motor, motor, etc. It is the core component of machine tool processing. The precision and efficiency of processing depend entirely on the factors of the spindle itself. Therefore, different types of electric spindles will be selected for different processing requirements of machine tools. The types of spindles are roughly divided into: high-speed, low-speed, air-cooled, water-cooled, automatic tool changer, double-headed shaft, pneumatic, mechanical and other types. From the application point of view, it can be divided into: milling, grinding, polishing, grinding, engraving, deburring, cutting, cutting, grinding, drilling, etc.
Below we show the application diagrams of three scenarios(wood machine、machinery industry、grinding machine processing、Cnc machine), and you can consult us for detailed questions such as products
1. The surface finish of the workpiece is greatly improved. The motor has good speed hard characteristics, and has high speed stability under load fluctuations, so that the surface finish of the workpiece can be significantly improved.
2. The transmission error is small. The length of the main transmission chain of the machine tool is zero, the motor directly drives the spindle, without any transmission error, the vibration of the spindle is significantly reduced, and the surface finish of the workpiece is significantly improved.
3. The deformation of the main shaft is small. The rotor of the motor is a rare earth permanent magnet structure, without excitation current, the rotor generates less heat, the axial stability of the spindle is good, and the machining accuracy of the workpiece is high.
4. Large power and torque. The motor is a rare earth permanent magnet synchronous motor with good power density and torque density. Compared with the asynchronous motor, under the same volume, the power and torque of the motor can be one level higher; even under the same power, because the rotor does not need excitation current, its torque is also significantly larger.
5. Rear direct drive structure design, flexible power configuration. The motor is located at the rear end of the main shaft, and the power of the motor can be freely matched with the thickness and length of the main shaft. The configuration is extremely flexible and can meet the application of various occasions where the radial space of the main shaft is limited.Spindle motor is usually also called high-speed motor, motor, etc. It is the core component of machine tool processing.
