Flexible Transport Technology
Technical Description
FHS Flexible Transport System(FTS) incorporates magnetic levitation technology into its conveyor system. Magnetic levitation (maglev) or magnetic suspension is a method by which an object is suspended without any support other than magnetic fields. In a maglev conveyor line, magnetic fields are generated by controlling coils, allowing objects to be levitated and moved within the magnetic field.
Technology Highlights
High-Precision Position Sensor Technology
FHS adopts a high-precision position sensor and absolute value encoder scheme to avoid zero finding when powered on;
Real time FPGA internal compensation solves the problems of position accuracy and lag during high-speed operation. The magnetic encoder solution reduces installation requirements, and with unique position compensation technology, it can ensure consistency in position feedback throughout the entire process.
Torque Ripple Suppression Technology
The lateral edge effect between the modules of the magnetic levitation system can cause significant torque fluctuations, making it a challenging technical issue to reduce these fluctuations.
FHS's self-developed motor controller, with its unique torque compensation technology, reduces torque ripple caused by optimized lateral edge effects. The intelligent feedforward technology improves response speed and ensures synchronization accuracy.
Mover Intelligent Scheduling Algorithm
The magnetic levitation system has numerous stators, and coordinating the related actions of the mover to meet the collaborative motion is another key technical difficulty of the magnetic levitation system.
The core scheduling algorithm of the magnetic levitation system is completely self-developed, including the stator scheduling algorithm, collision prevention algorithm, and the mover scheduling algorithm based on workstations and queues.
