Modern digital drive systems not only provide a faster processor, but also incorporate the basic principles of machine control systems. The improvement of the drive technology not only enhances the working performance of the machine in the traditional transmission form, but also allows the AC servo motor to directly drive the spindle or the moving shaft. With AC servo motors, you can create faster and more flexible machines and greatly reduce overall maintenance. Although the spindle has been configured with a DC drive motor for many years, the recent advances in the control methods and mechanical aspects of the drive power feedback facility have greatly improved the efficiency ratio between the spindle speed and the power supply voltage. The emergence of new control principles for permanent magnet motors has enabled system suppliers to focus on innovative designs of spindles to achieve higher torque. They operate at lower temperatures, extending service life and increasing operational reliability.
The application of linear motor is unmatched by traditional mechanical transmission in terms of speed and acceleration. A typical successful application of linear motor is the shaft feed drive of EDM machine. Sodick has made a good example and breakthrough. The ground has improved the machining efficiency and machining accuracy of the EDM machine. Large-scale CNC gantry key milling machine adopts linear motor technology for double-end drive. The acceleration of several tons of moving parts exceeds that of linear motor technology. It has obvious effect on large gantry CNC machine tools. The longer the stroke, the more obvious the effect, for example, for machining aircraft parts. CNC machines require a tens of meters of travel. Another application of linear motor technology is to make the linear motor a linear motor with rotational motion. This is a new type of rotary transmission. There is no gap in the forward and reverse commutation, it can be operated at high speed and high precision, or at very low speed. High-precision operation (applied to large-scale astronomical telescopes, one turn per day), the application of this technology on gear processing machines and CNC rotary tables will greatly improve its motion accuracy and reduce its manufacturing costs.
