Abstract:
Traditional transporter systems with belts and gears generate friction, reducing efficiency, which is a huge problem especially when used in clean rooms. Then, the Hybrid Magnetic Levitation System, which combines superconducting levitation stability and strong repulsion from permanent magnets, has been developed to solve this problem. This system consists of magnet rails with a Halbach Array to enhance the magnetic field on the upper side of the rail. Furthermore, the superconducting levitation offers stability without control, and air core coils on the magnetic rail generate propulsion force when interacting with the High-Temperature Superconductor (HTS) that pins flux from the magnetic rail. The principle of the propulsion method consists of magnetizing the back region of the HTS and demagnetizing its front region. This paper studies the influence of the excitation method using one and two propulsion coils, and the coil parameter in the propulsion force. The propulsion coils installed with different arrangements on the rails act on the HTS of the transporter and the propulsion force increased. From the results, the propulsion force increases as the coil self-inductance increases, but in a non-linear relation.
