On the basis of Maxwell’s equations with respect to  potentials, calculations of electromagnetic pro­cesses in movable and immovable areas of a turbogenerator cross-section in transformed and physical coordinate systems for no-load regime have been done. It has been shown that employing the method of equivalentization of the device tooth zones by continuous anisotropic media and ignoring the coordinate systems in which the process is considered in terms of mathematical field models lead to misrepresentation of real electro­magnetic phenomena.
