How to match the servo motor with the helical planetary gear reducer? Does the servo motor need to be distributed? However, in what kind of application occasions is it necessary to distribute the servo planetary gear reducer?
1. Occasions for high-precision use of heavy loads: This is necessary when it is necessary to move heavy loads and require precise positioning. Usually it is like aviation, medical, military technology, wafer equipment, robots and other automation equipment. Together they are characterized in that the torque required to move the load usually far exceeds the torque capacity of the servo motor itself. And through the reduction gear to achieve the improvement of the servo motor output torque, you can effectively deal with this problem.
2. Increased torque: The method of increasing the output torque can choose the method of directly increasing the output torque of the servo motor, but this method not only requires the use of a servo motor with expensive power, but also has a stronger structure of the motor and the increase in torque. It is proportional to the increase of the control current. At this time, a relatively large driver is selected. The increase in the power electronic components and related electromechanical equipment standards will increase the cost of the control system. The improvement of torque through planetary gear reducer can greatly reduce the cost.
3. Improve application performance: It is understood that the improper matching of load inertia is one of the major factors of unstable servo control. For a large load inertia, it can be distributed using the inverse square of the reduction ratio.
Very good equivalent load inertia to achieve a good control response. Therefore, from this point of view, the helical planetary reducer is a good match for the servo application control.
4. Add equipment service life: Planetary reducer can also effectively deal with the attenuation of the low-speed control characteristics of the motor. Because the controllability of the servo motor will be attenuated to some extent due to the decrease in speed, especially in terms of signal acquisition at low speed and the stability of current control, it is particularly easy to see. Therefore, the selection of helical planetary reducer can make the motor have a higher speed.
6. Decrease equipment cost: From the cost concept, assuming that the 0.4KW AC servo motor distribution driver needs to consume one unit of equipment cost, the 5KW AC servo motor distribution driver needs to consume 15 units of capital, but if you choose a 0.4KW servo motor and The drive can be allocated to a group of reducers to reach the aforementioned task of consuming 15 units of capital before it is completed, saving more than 50% in operating cost.
Therefore, the user decides to use the helical gear planetary reducer according to their processing needs. Generally speaking, there are low-speed, high-torque, and high-definition occasions in the work of the machine. Most planetary gear reducers are used. Ruiding planetary reducer has the advantages of large torque, ultra-quiet, high precision and long life. It is a good choice for helical planetary reducer used in servo system.
