Special Issue Information

Dear Colleagues,

Moving-magnet planar motors have features such as magnetic levitation, a direct-drive mechanism, a compact structure, a lightweight mover, a wireless mover, high reliability, high speed, and a high potential for ultra-precision motion. Therefore, this motor has gained increasing attention and has promising applications in precision and ultra-precision positioning systems as well as high-speed motion systems, especially those that pose extremely demanding environments, such as vacuum environments and cleanrooms. The typical applications of this motor are found in semiconductor lithography, transport systems, etc. The prerequisite for ultra-precise motion demands advanced sensing technology for obtaining submicron or even nanoscale position resolution under different travel ranges. However, achieving advanced sensing technology with a moving-magnet planar motor is a highly challenging task as conventional sensing technology is not appropriate for this emerging motor, which has a specifically structured wireless mover and 6-DOF motion, meaning six position signals need to be detected, and high position resolution demands need to be met for sensing. This Special Issue aims to address all types of methodologies, data processing, and testing techniques for advanced sensing technology for application in moving-magnet planar motors. Both original manuscripts and review manuscripts are welcome.

Topics of interest include, but are not limited to:

  • Advanced sensing frameworks for moving-magnet planar motors;
  • Advanced sensors for moving-magnet planar motors;
  • Sensor error modeling and online calibration for moving-magnet planar motors;
  • Sensing circuits or architectures for moving-magnet planar motors;
  • Sensing signal processing for moving-magnet planar motors;
  • Other emerging sensing applications for moving-magnet planar motors.

Recently, due to the development of semiconductor technology, high-performance memory and digital convergence technology that integrates and implements various functions into one semiconductor chip has been regarded as the next-generation core technology. In the semiconductor manufacturing process, various motors are being applied for automated processes and high product reliability. However, dust and shaft loss due to mechanical friction of a general motor system composed of motor-bearing are problematic for semiconductor wafer processing. In addition, in the edge bread remove (EBR) process after the photoresist application process, a nozzle position control system for removing unnecessary portions of the wafer edge is absolutely necessary. Therefore, in this paper, in order to solve the problems occurring in the semiconductor process, a six-degrees-of-freedom (6-DOF) magnetic levitation system without shaft and bearing was designed for application to the semiconductor process system; and an integrated driving control algorithm for 6-DOF control (levitation, rotation, tilt (Roll–Pitch), X–Y axis movement) using the force of each current component derived through current vector control was proposed. Finally, the 6-DOF magnetic levitation system with the non-contact position sensors was fabricated and the validity of the 6-DOF magnetic levitation control method proposed in this paper was verified through a performance test using a prototype.
