Abstract: A magnetic-controlled actuator (100) with an auto-locking function for joints of a manipulation arm mainly includes an inner-layer stator (10), an inner-layer mover (20), an outer-layer mover (30), an outer-layer stator (40), and a fixing shaft (50). The inner-layer mover (20), the outer-layer mover (30), and the outer-layer stator (40) have a plurality of permanent magnets, respectively. The fixed shaft (50) simultaneously penetrates through the inner-layer stator (10), the inner-layer mover (20), the outer-layer mover (30), and the outer-layer stator (40) forming a coaxial arrangement. The inner-layer mover (20) rotates relatively to the inner-layer stator (10) to output power from the actuator (100). Therefore, a cogging effect, which is produced due to interaction of the permanent magnets between the outer-layer mover (30) and the outer-layer stator (40), is automatically produces a high cogging torque for the actuator (100).

Abstract: An early-warning apparatus for health detection of a servo motor and a method for operating the same are applied to estimate vibration phenomenon of a CNC tool machine. First, a vibration signal is produced through a vibration detecting unit. Afterward, the vibration signal is sequentially sent to a data buffer. Afterward, the vibration signal is transformed in time and frequency domains through a time-frequency transforming unit. Finally, a deterioration index is calculated through a deterioration index calculating unit to obtain a health index which is calculated through a health index calculating unit. Therefore, the build-in vibration detecting unit is provided to dispense with additional external sensors. Furthermore, the vibration phenomenon of the servo motor of the CNC tool machine is estimated according to the health index, thus analyzing non-linear and non-stationary characteristics of the estimated vibration phenomenon.

Abstract: A tool-path calculation apparatus for a numerical controlled system and a method for operating the same are applied to a CNC tool machine. The tool-path calculation apparatus includes an upper controller and a servo driver. Firstly, an interpreter is provided to interpret the tool paths to produce a plurality of executable instructions. Afterward, the executable instructions are sent from the upper controller to the servo driver through a serial communication interface and stored in a queue buffer. Finally, the executable instructions are received and calculated by a tool path calculator to produce a plurality of points along the tool paths.

Abstract: An identification method for a human-machine interface using radio frequency and an identification system using the method is disclosed. First, a computer senses a radio frequency identification (RFID) tag and compiles a password table according to tag number of the RFID tag. The computer downloads the password table to a human-machine interface (HMI) as the compilation completed. When the human-machine interface executes identification process, the HMI senses the RFID tag via a radio frequency card reader and looks up in the downloaded password table if any tag number matches with the sensed RFID tag is recorded. If yes, HMI uses the identification password corresponding to the tad number in the password table for executing identification process.
