motors can be used in situations where constant speed drive is required. Chapter IV EPM1076 3 Chapter IV EPM1076 4 Angle in Electrical and Mechanical Unit -For 2 pole machine, when the rotor rotates for one revolution, the induce emf varies for one cycle. i.e. θ = θm, (refer to figure 2) -Where θ is the angle in electrical degrees or radians and θm is the mechanical angle. - For a 4 pole machine, as the rotor rotates for one revolution (θm = 2π), the induced emf varies

Jennifer L. Theresa Scott ENC 1101: Comp 1 June 8th, 2016 The Machines of Tomorrow Technology is everywhere. You go out in public and all you see is everyone concentrating on their phones. Technology allows people to communicate with one another and share information. Even if someone doesn’t own a computer or a phone, there is some type of mobile device, computer, or even television that you can get too to get the latest news. I was born in 1999, where technology wasn’t as big as it is now

you are installing cable in conduits within a structure, be sure that you have allowed enough room for the cable or cables you are installing. Tray and duct installation is used inside structures and is similar to installation methods used for electrical wiring. Because many optical fiber cables are nonconductive, some of the requirements and restrictions for copper do not apply to fiber. When the optical fiber rests in trays or horizontal ductwork the weight of the cable is usually not a factor

Use of Electrical Power Systems: The use of electrical power as an alternative to drive the aircraft systems and its sub-systems that had earlier been driven by hydraulic, and mechanical systems is becoming a ruling trend in the aerospace industry. Devolopment in the power electronics provide the technology to improve the overall efficiency,functioning and safety of aircraft systems operation. The More Electric Aircraft (MEA) is being devoloped with a goal of distribution of electrical power across

Santiago Diaz Fin 301 Final Project The purpose of this report is to analyze the data constructed by PowerCo to determine the potential profit or loss of building a new power generator. Because of the increase in demand, the current power plant will not be able to supply the demand for electricity over the next 10-12 yrs. A proposal has been made, and this report will determine if a new power generator should be constructed. Present Value (Pv) of Expected cost, Cf=Cash flow Pv=Cft/(1+r)˄t
