In a separately excited DC generator, the field winding is excited by an external independent source. In fact, the same dc machine can be used interchangeably as a generator or as a motor. LECTURE NOTES ON ELECTRICAL MACHINES-II Fig. The types discussed in the following paragraphs are typical of the more predominant ones in use. Generator Types Various types of alternating current generators are utilized today; however, they all perform the same basic function. Volume 2 of 4 Module 3 - DC Circuits This module introduces the rules associated with the reactive components of inductance and capacitance and how they affect DC circuits. Lecture Notes Elements of Electrical Machines 12 Figure 2.3 : Torque in DC Motor Figure 4 : Current Flow in DC Motor Constructionally, there is no basic difference between a dc generator and motor. Course notes files. Induced voltage in a DC generator: E = B L v (Faraday’s Law) For a DC generator, this equation can be manipulated to give: Eo = C n Φ / 60 Eo = voltage between the brushes (V) N = speed of rotation (rpm) Φ = flux per pole (Wb) C = total number of conductors on the armature* *The number of conductors equals the number of slots (coils) times the 3 DC GENERATOR The direct current (DC) generator (Dynamo) is only used for special application or local power generation. 3.3: The phase voltage of the generator is just the sum of its internal generated voltage and its armature reaction voltages. University. DC-Generator 2 - Lecture notes 2. There are generally three most important characteristic of DC generator: Magnetic or Open Circuit Characteristic of Separately Excited DC Generator The curve which gives the relation between field current (I f) and the generated voltage (E 0) in 3.2d, compared to the field predicted by the cylindrical rotor theory.
