A new form of the tensor equations of electrical machines

Previous tensor methods applied to electrical engineering systems have been based on Lagrange´s equations, which are not always suitable for non-holonomic systems. As a consequence, the defining equations lose much of their simplicity and the component terms in the equations may no longer be tensors. The paper presents a new set of equations based on the principle of least curvature. These equations are suitable for both holonomic and non-holonomic systems, and their application is shown by examples.
