In this chapter the retrospective analysis of the theory condition and practice of the interconnected multi-motor controlled electric drives is performed.Research and development in this field developed in the last third of the 20th century.In these years, virtually was created the interconnected multi-motor drives theory but the research majority in the field of interconnected electric drives with elastic-plastic and distributed connections is not realized.Now the construction principles of means and control systems for the interconnected electric drive with the help programmaticallyhardware functional modules are realized.These modules were created on the basis of new semiconductor converters and the logical controllers.In the future will develop the theoretical research and the practical applications on the basis of the fuzzy neural networks, including the control in the online modes, the sliding modes with use high-speed controllers.Development of new exact synchronization methods of the electric multi-motor drives will ensure the creation of a multi -motor direct-drive.New group of mechatronic objects will be created by the interconnected multi-motor electric drives which not only have the traditional feedbacks on speed, currents, tension etc., and also the feedbacks based on the technological variables of machines and mechanisms: torques, efforts, pressure, vibrations, expenses etc. Development and creation of adaptive systems which interconnected through a processed material or working body of electric drives with is elastoplastic links (which properties change in the course of work) is an actual problem.Considerable interest represents application of the fuzzy-regulation methods for the creation of the control systems by the nonlinear nonstationary interconnected electromechanical systems.Practical realization of the robust control methods for the multi-motor electric drives in the emergency situation or emergency modes is also the perspective direction Key words: multi-motor semiconductor electric drives, the theory, technical solutions, retrospective, condition, prospects
