The types discussed in the following paragraphs are typical of the more predominant ones in use. In fact, the same dc machine can be used interchangeably as a generator or as a motor. Generator Types Various types of alternating current generators are utilized today; however, they all perform the same basic function. University of KwaZulu-Natal. Course.

EE3010 ElectricalDevicesand Machines LECTURENO6 Introduction To DC Machinery Fundamentals DC … 3.2d, compared to the field predicted by the cylindrical rotor theory. DC-Generator 2 - Lecture notes 2. 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. DC-Generator 2 - Lecture notes 2. 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 1. slip rings link the rotor’s field winding to an external dc source 2. dc generator exciter • a dc generator is built on the same shaft as the ac generator’s rotor • a commutator rectifies the current that is sent to the field winding • Low speed, large hydro-generators may have more than one hundred poles. 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. The basic construction of a dc Course notes files. Module 2 - Basic DC Theory This module describes the basic concepts of direct current (DC) electrical circuits and discusses the associated terminology. 3.3: The phase voltage of the generator is just the sum of its internal generated voltage and its armature reaction voltages. In a separately excited DC generator, the field winding is excited by an external independent source. The resulting stator magnetic field is shown in Fig. • For a DC MOTOR, the efficiency is the electrical output power divided by the mechanical input power, or • For a DC GENERATOR, the efficiency is the electrical output power divided by the mechanical input power, or • Note that the efficiency of a DC machine will vary with … Electrical Machine 1 (ENEL3MA) Uploaded by.
