Good day.
Your project description is truly broad.
Do you need someone to analyze the dynamics of a machine, whether it is an under or over damped system, deriving a model for the dynamics to be used in an active feedback control system?
Or is this an electrical machine where power consumption, heat, or other operational characteristics are needed?
Do you perhaps need some physics modelling, EM fieldtheory...?
I love all mathematics - Vector calculus, Complex number theories, Trancendental functions, Fourier/Laplace series, and more
I am available to derive the mathematical model you seek, and to provide a technical white paper if required.
