This paper deals with the finite element based optimal design of a wind energy based heater. The proposed device ensures the conversion of the wind kinetic energy into heat by means of Joule effect of eddy currents induced in the wall of a tubular stator due to the rotating magnetic field produced by rotor permanent magnets. The transient electromagnetic field problem associated to the operation of the device is solved using a 2D finite element approach based on vector potential formulation. A simplified method for the 2D heat transfer analysis of the device is also proposed. The influence of stator wall material and thickness, number of poles, the airgap thickness and the geometrical parameters of the permanent magnets is analyzed in the aim of optimizing the studied heater.
