Types of DC Motors: Series, Shunt, Compound, Permanent [PDF]
So from the torque equation of the dc motor, we get. T g = K a φ I a. In this case, the torque is varied by varying field flux φ, and it is independent of the armature current I a. #2 Permanent Magnet DC Motor. A permanent magnet DC motor has armature winding like a usual motor, but it does not have field winding.
Characteristics of DC Shunt Generator
In this article, you will learn the characteristics of a dc shunt generator. A shunt generator is a type of dc generator in which the field winding is connected in parallel with the armature winding so that the terminal voltage of the generator is applied across it. The shunt field winding has many turns of fine wire having high resistance.
Speed Control of DC Motor (Shunt & Series) | Electrical4U
Speed adjustment of a DC series motor by field control may be done by:. Field Diverter Method; Tapped Field Control; Field Diverter Method. This method uses a diverter. Here the field flux can be reduced by shunting a portion of motor current around the series field. Lesser the diverter resistance less is the field current, less flux therefore …

Methods of Voltage Control in Power System
4. Shunt Capacitors – The shunt capacitors are the capacitors connected in parallel with the line. It is installed at the receiving end substation, distribution substations and in the switching substations. The shunt capacitor injected the reactive volt-ampere to the line. It is placed in the three phase bank. 5.
What is Series and Shunt Compensation?
In electric power transmission, series compensation is the use of a capacitor or inductor in series with a transmission line to improve its voltage transmission characteristics. Series compensation …
Speed Torque Characteristics of DC Motor (Shunt & Series)
Speed-Torque Characteristics of DC Series Motor. The speed-torque characteristics of DC series motor can be obtained or derived from the torque-current and speed-current characteristics of DC series motor. Therefore, armature torque and speed has inverse relationship as shown in figure (3). We know that,

What is Shunt Compensation in Power System?:
Shunt Compensation are connected in shunt at various system nodes (major substations) and sometimes at mid-point of lines. These serve the purposes of voltage control and load stabilization. As a result of installation of shunt compensation in the system, the nearby generators operate at near unity pf and voltage emergencies mostly do not arise.
Static VAR Compensator
A static VAR compensator is a parallel combination of controlled reactor and fixed shunt capacitor shown in the figure below. The thyristor switch assembly in the SVC controls the reactor. The firing angle of the thyristor controls the voltage across the inductor and thus the current flowing through the inductor.
Capacitor
In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, [1] a term still encountered in a few compound names, such as the condenser microphone is a passive electronic …
