Separately excited shunt generator

In summary, the conversation discusses a question regarding a separately excited shunt generator's nameplate data and the calculation of various parameters such as the full load armature current, EMT generated at full load, power dissipated in the shunt field, and power dissipated in the armature. The speaker also mentions sketching the equivalent circuit to better understand the concept.

I have a question that iv been stuck on for wile. I am in year 2, electronic engineering and I am having a little trouble with this.

A separately excited shunt generator has the following nameplate data, 50kW, V(FL) = 125, R(A) = .01 ohms, R(F) = 16 ohms and an excitation voltage of 125 VDC.

Calculate the full load armature current
The amount of EMT generated at full load
Power dissipated in the shunt field
Power dissipated in the armature

Step 1 is to sketch the equivalent circuit and mark on it the data you are given. This shows that you at least understand what a DC shunt generator is.

thanks, i looked at it for a bit and redrew it, then realized how easy it actually was.
 

1. What is a separately excited shunt generator?

A separately excited shunt generator is a type of DC generator that uses a separate source of DC power to create an electromagnetic field in the stator, which induces a current in the armature winding to produce electricity.

2. How does a separately excited shunt generator work?

The separately excited shunt generator works by using a separate DC power source to create a magnetic field in the stator. This magnetic field then interacts with the rotating armature to produce an induced current, which is then converted into electricity.

3. What are the main components of a separately excited shunt generator?

The main components of a separately excited shunt generator include the stator, which houses the field winding, the rotor or armature, which rotates within the stator, and the brushes and commutator, which allow for the flow of current from the armature to an external circuit.

4. What are the advantages of a separately excited shunt generator?

The main advantages of a separately excited shunt generator include its ability to maintain a constant voltage output, even with varying loads, and its ability to operate at high speeds without overheating. It also has a simple and reliable design.

5. What are the applications of a separately excited shunt generator?

A separately excited shunt generator is commonly used in power generation systems, electric vehicles, and industrial machinery. It is also used in battery charging systems and as a backup power source in case of power outages.
