In different transmission equipment, we can see different reduction motors, such as servo for reduction motor of CNC cutting machine, three-phase asynchronous motor for packaging machine, DC-AC shaft reduction motor for sewage treatment equipment, and gear reduction motor for animal husbandry system.
Why do different equipment use different reduction motors? Because of the different working conditions of different equipment, the demand for the reduction motor is different.
Taking the servo motor used in the decelerating motor of CNC cutting machine as an example, it is shown that in general, the cutting machine has a very high accuracy requirement on the size and other aspects of the objects to be cut, and the reason why the cutting machine can cut the objects is under the control of the program designed in advance, and the use of the servo motor will make the CNC machine more efficient and more accurate.
The function of servo motor is to convert the input voltage signal (i.e. control voltage) into the angular displacement or angular speed output on the shaft, which is often used as the actuator in the automatic control system, so the servo motor is also called the actuator.
Nantong Far East micro Special Motor Co., Ltd., located at No. 1, Yuandong Road, Sunzhuang Town, Hai'an County, Jiangsu Province, is a large-scale backbone enterprise in the micro special motor industry. It is a motor and electrical production group enterprise integrating scientific research, production, development and operation, mainly serving the machine tool and machinery industries.

The performance of servo system controlled by servo motor has these characteristics:
1. High displacement accuracy
Displacement accuracy: refers to the degree of conformity between the displacement of the machine tool workbench required by the command pulse and the actual displacement of the workbench converted by the servo system
2. Good stability
Stability: refers to the servo system under the given input or external interference, can achieve new or restore to the original balance state after a short adjustment process.
3. High positioning accuracy
Positioning accuracy: refers to the accuracy of the output quantity which can reproduce the input quantity
4. Fast response
5. Wide speed range
Speed regulation range: refers to the ratio of the highest speed and the lowest speed that the mechanical device requires the motor to provide
6. Good system reliability
7. Low speed and high torque
That's why the servo system is selected for the decelerating motor of the CNC cutting machine.
