Abstract :
A novel magnetic levitation conveyor system consists of a linear synchronous motor and a hybrid electromagnetic levitation system was designed and built. The linear synchronous motor for propulsion was constructed using non-contact digital commutation while the hybrid electromagnetic levitation system was implemented using two permanent magnets and electromagnets for vertical levitation. The proportional-integral-derivative (PID) controller was coded using PIC18F4520 microcontroller to control the air gaps of a non-linear hybrid electromagnetic levitation system. The responses of both simulation and experiment show some agreement as the magnetic levitation and propulsion are both achievable in the proposed design.
