How Do I Choose the Best Lathe Motor?

The spindle motor is also called a high-speed motor, which refers to an AC motor with a rotation speed exceeding 10,000 rpm. It is mainly used in wood, aluminum, stone, hardware, glass, PVC and other industries. It has the advantages of fast speed, small size, light weight, low material consumption, low noise, low vibration, etc., and it has been increasingly valued and applied by related industries. . In a modern society where science and technology is advancing at a high speed, due to the wide application of the spindle motor, coupled with its meticulous workmanship, fast speed, and high processing quality of the motor, other ordinary motors cannot meet the technical requirements of the spindle motor and play in the industrial production Important role, so the spindle motor is particularly favored in the country and even the world.

In European and American countries, this technology is mainly used in power, missile, aviation and other industries. Due to the high technical requirements of the industry, high-quality, high-tech, high-precision spindle motors are required. China is also slowly adopting this technology. The Three Gorges Project,

There are two types:

1. During use, iron hooks should be used to clean the leakage at the lower end of the main shaft drain cover to prevent abrasive debris from blocking the leaking pipe.

I. CNC machine tools have different requirements for the spindle motor and servo motor:

The requirements of CNC machine tools for feed servo motors are:

(1) Mechanical characteristics: The speed drop of the servo motor is small and the stiffness is required;

(2) Requirements for fast response: This is stricter when contour processing, especially high-speed processing of processing objects with large curvatures;

(3) Speed adjustment range: This can make the CNC machine tool suitable for a variety of different tools and processing materials; suitable for a variety of different processing technologies;

(4) A certain output torque and a certain overload torque are required. The nature of the machine feed mechanical load is mainly to overcome the friction of the table and the resistance of cutting, so it is mainly the "constant torque" nature.

The requirements for high-speed electric spindles are:

(1) Sufficient output power. The spindle load of CNC machine tools is similar to "constant power", that is, when the machine spindle speed is high, the output torque is small; when the spindle speed is low, the output torque is large; The spindle drive must have the property of "constant power";

(2) Speed adjustment range: In order to ensure that the CNC machine tool is suitable for various tools and processing materials; to adapt to various processing technologies, the spindle motor is required to have a certain speed adjustment range. But the requirements on the spindle are lower than the feed;

(3) Speed accuracy: Generally, the static difference is less than 5%, and the higher requirement is less than 1%;

(4) Fast: The spindle drive is sometimes used for positioning functions, which requires it to be fast.

Second, the output indicators of the servo motor and the spindle motor are different. The servo motor uses torque (Nm), and the spindle uses power (kW) as an indicator.

This is because the servo motor and the spindle motor have different roles in CNC machine tools. The servo motor drives the worktable of the machine tool. The load damping of the worktable is the torque that is converted to the motor shaft. Therefore, the servomotor uses the torque (Nm) as an indicator. . The spindle motor drives the spindle of the machine tool, and its load must meet the power of the machine tool, so the spindle motor takes power (kW) as an indicator. This is customary. In fact, through the conversion of mechanical formulas, these two indicators can be calculated mutually ^[3] .
