This paper presents a synchronous control scheme for a high-speed machine tool using linear servomotors. The gantry machine tool is mainly composed of three linear servomotors: one for the X-axis and the other two as a parallel pair for the Y-axis. The advantage of such a structure with two parallel linear servomotors for a single axis is to enable the machine to operate at high speed and acceleration...
The ability to sustain a smooth-running practice is very important in dentistry. Because of this reason, Electric handpieces driven by permanent magnetic synchronous motors (PMSMs) have been increasingly applied in dentistry and have replaced air-driven ones due to their high efficiency and ability to sustain constant speed while operating. Additionally, they produce little noise compared to the high...
