Feb 01, 2018nbsp018332author adolfo garcia. in electrical machines, the aim is generally to attain the highest possible efficiency. efficiency is given by the ratio of the output power and the input power p load and p e in figure 1.that is, the efficiency will be higher if a reduction of the losses in the system p cu, p mag and p mech is achieved. typically, the losses in an electrical machine are the winding ...
Each dc machine can act as a generator or a motor. hence, this classification is valid for both dc generators and dc motors. dc machines are usually classified on the basis of their field excitation method. this makes two broad categories of dc machines i separately excited and ii self-excited.
In order for the rotating machine to turn and generate electrical currents, the permanent magnets are used, as is the ac and dc input currents. the magnetic field creates the torque in the electric motor and the electromagnetic laws help the generator to create electric current in the magnetic field.
