Permanent Magnet Synchronous Motor (PMSM) — Leading the New Generation of Technological Transformation in Motorized Spindles
The motorized spindle is a core functional component of CNC machine tools. Its performance directly affects the machining accuracy of CNC machine tools and determines their production efficiency and yield rate. As the key and core of the motorized spindle drive system, the built-in spindle motor serves as an important power executive component of the drive system. Its performance directly influences critical technical indicators of CNC machine tools such as dynamic rigidity, machining accuracy, machining speed, vibration, and noise. Therefore, the motor has a significant impact on the machine tool’s performance, structural layout, and manufacturing cost.
