Common control methods in motorized spindle operation

Common control methods in motorized spindle operation

Dec 03, 2020

In machine tool processing, the role of motorized spindle can not be ignored, and its control mode will also have a greater impact on its performance. The frequency conversion speed regulation method is generally used in the machining of motorized spindle. At present, there are three control methods: general frequency conversion drive and control, vector control driver drive control and direct torque control.

Direct torque control (DTC) is a new type of high-power AC speed regulation technology developed after vector control technology. Its system structure is simple and clear, which is more suitable for the drive of high-speed motorized spindle, and can satisfy the dynamic and static characteristics of high-speed motorized spindle with high-speed, wide speed regulation scale and high-speed instantaneous stop.

The structure of frequency conversion drive and control is relatively simple, which is generally used for grinding machines and general high-speed milling machines, and the processing is limited. In the actual processing process, the control mode of motorized spindle should match the machine performance and product quality.

The above points are about "what are the components of motorized spindle". I believe that after reading the introduction of this paper, we will have our own understanding of this aspect, and we can solve the problems of grinding motorized spindle in the future. Here, we recommend you learn more about grinding motorized spindle, Anyang Yinrui electromechanical Co., Ltd. and other relevant information, hope to help you!
