Abstract: A conveyor system includes a moving stage, a track, a control circuit and a driver. The moving stage has a plurality of magnets and an optical scale. The track carries the moving stage and includes a first work area provided with a plurality of Hall sensor modules and a second work area provided with the Hall sensor modules and a read head module. When the moving stage is in the first work area, the Hall sensor module generates a first sensing signal. When the moving stage is in the second work area, the Hall sensor module generates the first sensing signal and the read head module generates a second sensing signal. The control circuit determines the position of the moving stage based on the first sensing signal and the second sensing signal, and generates a driving signal. The driver drives the coil windings according to the driving signal.

Abstract: The present disclosure provides a work equipment system and a control method therefor. The work equipment system includes a work equipment, a temperature sensor and a controller. The work equipment includes a motor device, and the motor device is configured to provide a motive power to a load device. The temperature sensor is configured to measure a motor temperature. The controller is configured to: calculate a first current based on a required motive power command and electrical parameters; calculate a temperature difference between the motor temperature and a preset temperature; calculate a thermal power based on the temperature difference and a thermal resistance; calculate a second current based on the thermal power and the motor resistance; and compare the second current to an effective value of the first current for determining whether the second current is smaller than the first current.

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.
