Inclination control of the carrier in the magnetically levitated conveyance system using the linear stepper motor

The magnetically levitated conveyance system has been developed. Most system consists of the levitation (and guidance) section and the thrust one. Therefore, in this research, levitation and thrust are performed in the same system. The experimental device designed by the three-dimensional FEM analysis has been developed. In the conventional system, difference of the attractive force between the ends of the U-shaped iron core generates the inclination of the carrier. By changing the excitation method on the primary of the linear stepper motor, the inclination of the carrier is reduced. The carrier is levitated around the target levitation gap in the levitation experiment using the new excitation method.
