A generalized analytic mathematical model of the electromechanical converter as a control object

The paper proposes an analytical generalized mathematical model of the electromechanical converter as a control object, which allows the synthesis of laws of control in the current circuits and of the AC drive torque. It offers a system of model equations combining winding method and energetic method for obtaining electromagnetic coordinates of electric drive (MMF, EMF, electromagnetic torque). It gives recommendations for development of PC-based computational algorithms. The results of the simulation are specific electromagnetic torques of various electromechanical converters, coil EMFs, rotor speed and current frequency in windings. This model is recommended at the first stage of estimate calculation with the following assumptions: electromechanical converter is not saturated, steel magnetic conductivity is infinite, and there are no scattering flows. More accurate magnetic field calculations require numerical models based on the Maxwell equations and finite element method.
