Abstract: The article research power processes for optimal modeling and design of special electric drives with asynchronous motors. In order to create various types of electric drives with optimal weight and size and energy indicators, it is necessary to accurately determine the values of electric currents in the windings, electromotive forces and corresponding flux couplings in the stator and rotor of the components of the devices under study. The main difficulty in research and determining the parameters is the constant change of these values as a result of the change in the electrical parameters of the supply voltage system, the spatial position of the movable parts of the drive relative to the stationary ones and the features of the technological process. This leads to a change in the mutual location of the stator and rotor field axes, phase shear angles of electric currents and electromotive forces of components of special electric drives. The research of electric power processes using methods based on electromechanical energy conversion allows you to quite accurately determine the parameters you are looking for. Determining the value of stored energy will allow you to model and design special electrical drives quite accurately without appropriate experimental adjustment. Besides, this approach allows determining energy parameters at any moment of time, which makes it possible to determine instantaneous values of the desired parameters, including instantaneous values of force and torque on the shaft of the electric drive. Accurate and correct determination of energy ratios in the studied electric drives will allow not only to carry out optimal design, but also to create optimal control systems for electric drives taking into account the technological features of a particular production.
