A Contribution to the Theory of Rotating Electrical Machines

This contribution introduces a vector interpretation to unify the description of torque development in rotating electrical machines. The motivation behind this attempt is necessity applying different physical and calculation methods, such as Lorentz force, Maxwell stress tensor, co-energy methods etc., for predicting estimating components, e.g. synchronous torque, oscillating cogging reluctance unified model describes estimates components machines with an apprehensible concise formulation. Beyond that, other most frequently used tools terms field machines, Park Clark transformations, phasor diagram can be derived directly from model, which has also simplifying didactic conventional course
