Thermal Analysis of the advanced single-stage planar actuator

Abstract

The Advanced Single-stage Planar Actuator (ASPA) is a nanometer-accurate magnetically levitated planar actuator with moving magnets. It is designed at the Eindhoven University of Technology in collaboration with an industrial partner active in the semiconductor industry. The first version of the ASPA is already industrialized. In order to significantly improve both accuracy and acceleration, the design procedure of a new ASPA is started. The goal of this project is to generate a thermal model of the ASPA and to study possible cooling concepts of the new version. The thermal model should be sufficiently detailed in order to account for various thermal phenomena presented in the motor, such as heat transfer between the stator and mover, cooling system and conduction heat transfer between various layers.

Heat transfer

Heat transfer is a discipline of thermal engineering that concerns the generation, use, conversion, and exchange of thermal energy (heat) between physical systems. Heat transfer is classified into various mechanisms, such as thermal conduction, thermal convection, thermal radiation, and transfer of energy by phase changes. Engineers also consider the transfer of mass of differing chemical species (mass transfer in the form of advection), either cold or hot, to achieve heat transfer.

Convection (heat transfer)

Convection (or convective heat transfer) is the transfer of heat from one place to another due to the movement of fluid. Although often discussed as a distinct method of heat transfer, convective heat transfer involves the combined processes of conduction (heat diffusion) and advection (heat transfer by bulk fluid flow). Convection is usually the dominant form of heat transfer in liquids and gases. Note that this definition of convection is only applicable in Heat transfer and thermodynamic contexts.

Radiative cooling

In the study of heat transfer, radiative cooling is the process by which a body loses heat by thermal radiation. As Planck's law describes, every physical body spontaneously and continuously emits electromagnetic radiation. Radiative cooling has been applied in various contexts throughout human history, including ice making in India and Iran, heat shields for spacecraft, and in architecture. In 2014, a scientific breakthrough in the use of photonic metamaterials made daytime radiative cooling possible.
