All the things in nature are under influence of gravitational field, so is the electric machine. It affects not only physical structure of the electrical machine, but also electromagnetic field produced in the stator and rotor of the machine. Power generated in electrical machine, voltage produced, current flows in the machine, all are functions of electromagnetic field. When there is switching on electromagnetic field, immediately it will influence the gravitational field and in turn make variations in the basic parameters of electrical machine. in this paper, examination of the effect of gravitational field on electromagnetic field and its electrical parameters of electrical machines at microscopic level is studied. General electrical machine is assumed in this study. Gravitational field disturbs electric flux density, electric field strength, magnetic flux density, magnetic field strength and in result permeability and permittivity changes. Due to change in these electromagnetic parameters, inductance (L) & capacitance (C) changes, which in turn alters X, and X,,. Finally these changes make effect on current and power of electrical machines.
