Abstract:

Applications of magnetic levitation are of interest in several fields, such as energy harvesting, transportation, micro-robotics, etc. Magnetic Levitation has also found itself to be of interest in the field of Additive Manufacturing (AM). The principle of Eddy Current (EC) levitation is used to build the levitation system. The primary objective of the work presented here is to validate the viability of this EC levitation system within the AM environment through FEA (Finite Element Analysis). This validation of this levitation system includes the computation of levitation forces in the vertical axis, restoration forces in the x-y plane and temperature increase. The optimization of the dimensions of the levitator and the embedded coils are also described here. A strong emphasis is also placed on the determination of the levitation ability of various aluminum alloys with applications in the AM environment. Following this, input parameters (frequency and magnitude of AC supplied to the system) are computed through the principle of least square curve fitting. These parameters are validated through FEA. Through the work conducted here, it was concluded that EC levitation is applicable for AM.
