Depending upon the source of electrical energy, there are two types of electric motors: A.C. Motors: Motor that converts alternating current energy into mechanical energy is called A.C. motor. D.C. Motors: Motor that converts direct current energy into mechanical energy is called D.C. motor.OWER LOSSES IN A DC MOTOR. The basic function of dc motor is to convert electrical energy into mechanical energy. Whole of the input energy is not converted into useful output energy but a part of the input energy is converted into heat and the same is lost.
Concatenation in Java is the operation of joining two strings together. You can join strings using either the addition (+) operator or the Stringâs concat() method.
Virtual concatenation (VCAT) is an inverse multiplexing technique creating a large capacity payload container distributed over multiple smaller capacity TDM signals. These signals may be transported or routed independently.Virtual concatenation has been defined for SONET / SDH, OTN and PDH path signals.CAT helps in providing services at a lower cost and more quickly than contiguous concatenation. However, it creates differential delay whereby each path that is created, represented by a VT has a different propagational delay across the network. The difference in these delays is called differential delay (D).
