• Description

    During development of a variable electrical water pump, based on an eddy-current magnetic coupling, the analytical solution should be proved and the design for prototype assembly tested by simulation. The FEA analysis was important to check all machine function and test method, based on the theory developed by DAVIES[1965]. This theory is a 2D analytical solution for eddy-current coupling, for heteropolar and homopolar configuration. Based on that, initially, an 2D-transient simulation was done to compare the analytical torque calculation with the simulation result. After theory validation, it was possible to test and develop different magnet materials to improve the energy conversion efficiency. Finally, an 3D-transient simulation was done due the geometry complexity in order to predict the real performance by simulation. The software in use is Magnet.
