What are series and shunt generator?

In a series-wound generator, the output voltage varies directly with load current. In the shunt-wound generator, the output voltage varies inversely with load current. A combination of the two types can overcome the disadvantages of both. This combination of windings is called the compound wound DC generator.

What is a shunt DC generator?

A shunt generator is a type of direct current electric generator in which field winding and armature winding are connected in parallel, and in which the armature supplies both the load current and the field current.

What is shunt and series?

The shunt series is a set of radiographic images performed to assess the location and integrity of a ventriculoperitoneal shunt.

What are the 3 types of DC generators?

The three types of self-excited DC generators are:

  • Series Wound Generators.
  • Shunt Wound Generators.
  • Compound Wound Generators.

What is the principle of shunt?

Construction and Working Principle The working principle of a DC Shunt Motor is, whenever a DC motor is turned ON, then DC flows throughout stator as well as the rotor. This current flow will generate two fields namely pole as well as the armature.

What are the two types of shunt compound DC generator?

There are a series and a parallel winding with the armature and include two types of short shunt compound wound generator and long shunt compound wound generator.

What is the difference between shunt DC machine and series DC machine?

In a DC shunt motor, the armature and field (shunt) windings are connected in parallel. In contrast, for a series-wound DC motor, torque increases as the square of armature current. This exponential torque-current relationship allows series-wound DC motors to provide high starting torque and handle high startup loads.

What is the difference between shunt and series DC motor?

A series motor respond by decreasing its speed with small increase in current for a given load torque. A shunt motor holds its speed nearly constant with large increase in input current for same amount of load torque.

Where is DC shunt motor used?

shunt motors are used wherever there is a request for stable speed. Shunt DC motors can be used in centrifugal pumps, lifts, weaving and lathe machines, blowers, fans, conveyors, spinning machines, and more.

Why May a DC shunt generator fail to self excite?

Absence of Resuidal Magnetism

  • Wrong field winding connection
  • Wrong direction of Rotation
  • Resistance of Field-winding (Rf) > Critical Resistance (Rc)
  • Speed of Rotation (N)< Critical speed (Nc)

    • What is the application of a DC shunt generator?

    They are used for general lighting.

  • They are used to charge battery because they can be made to give constant output voltage.
  • They are used for giving the excitation to the alternators.
  • They are also used for small power supply (such as a portable generator ).

    What is a shunt on a DC motor?

    In a DC shunt motor, the armature and field (shunt) windings are connected in parallel. A parallel circuit is also known as a shunt circuit; thus, the term, “shunt motor” is used.

    What are the characteristics of a DC generator?

    Characteristics of DC Generators – Shunt, Series & Compound Characteristics of Separately Excited DC Generator : In a separately excited dc generator, field windings are energized by a separate external source, rather than using the same supply used to Characteristics of Self-excited DC Generators : i. ii. iii.
