Abstract:
A moving-magnet transfer platform includes a mover part, a driving part and a stator part. The mover part includes a moving table and a magnet assembly. The stator part includes plural coils, plural switch elements, a current sensor, an electric angle detector, plural magnetic field sensors and a signal processor. The plural switch elements are connected between the driving part and the corresponding coils. When the magnet assembly is moved to a position of the corresponding coil, a magnetic field change is detected by the corresponding magnetic field sensor. The signal processor is used for controlling operations of the plural switch elements. When the magnet assembly is moved to the position of the corresponding coil, the corresponding switch element is turned on under control of the signal processor, so that the moving table is moved with the magnet assembly.
