![]() ![]() ![]() Is proportional to half its coefficient of cosine effect of phase angles (CCEPA). Is involved in the motion of the vibrating system it has excited, its relative moment of inertia is reduced. difference between the residual electromagnetic torques of the two motors. To implement frequency capture, the torque of frequency capture should be greater than or equal to On the existence and stability of zero solutions for the average differential equations of small parameters over the average In the average method of modified small parameters, the synchronization of two coupled exciters is converted to a problem This project consists of four chapters, the first chapter is the Introduction and we speak for electrical distribution definition, history and objective of the project as well as a short on the project, and in the second chapter we have performed calculations for the project, such as lighting accounts, and in the third quarter we have a brief explanation of the parts electrical main used in electrical design, either Chapter IV it is a practical part of the project, which consists of electrical diagrams of the building, which was designed by the engineering program "Auto CAD 2015", have the results of the designs program efficiency at work showed the possibility of adoption by electrical engineers in electrical design of buildings of all kinds, whether office or residential buildings and schools and companies and factories and theaters. Electrical distribution in multi-stories buildings is one of the most important work because his influence is obvious and important on the nature of the building both in terms of engineering, healt h and aesthetic as well as on the type and nature of the use. ![]()
