The purpose of this paper is to introduce a reverted way to design electrical machines. The authors present a work ﬂow that systematically yields electrical machine geometries from given air gap ﬁelds.
The solution process exploits the inverse Cauchy problem. The desired air gap ﬁeld is inserted to this as the Cauchy data, and the solution process is stabilized with the aid of linear algebra.
The results are veriﬁed by solving backwards the air gap ﬁelds with in the standard way. They match well with the air gap ﬁelds inserted as an input to the system.
The paper reverts the standard design work ﬂow of electrical motor by solving directly for a geometry that yields the desired air gap ﬁeld. In addition, a stabilization strategy for the underlying Cauchy problem is introduced.
