Carbon Brush

About Carbon Brushes:






For many years inventors were trying transmit current form a stationary body to a rotating body. It was the main obstacle in rotating machinery. Finally they found out a way. Initially it was done by bundling copper wires and fixed then with stationary body and keep contact with the rotating body. In this way the copper bundles looked like paint brush. And the word brush came from there. 

With the development of knowledge and technology and after years of experiment finally a well structured process invented. Now in almost all modern technology different grades of carbon blocks are used as the transmitting medium. Though they don't look like brush but as a tradition they are well known as carbon brush.

With the help of brush holder and spring the remain touched with the rotating body and transmit current.

Why Carbon is Selected as the medium?

About Carbon Brushes:






In all modern technology for transmitting current from a stationary body to a rotating body carbon brush is used. The main reasons for using carbon are as follow:

a) First of all is its conductivity which is as like as metal.
b) The main disadvantage metal is that in some temperature metal melts. Most often metal welded because of this property. On the other hand carbon does not melt. It does not hold any liquid state. It vaporize directly from solid state. It is another very good advantage of using carbon brush. No probability to be welded with commutator or slipring. Also its evaporation  temperature is also too high. It is almost 3000 to 4000 degree Celsius.
c) Carbon is lighter than many metal which also make it's inertia much low and because of this low inertia carbon brush can move easily and smoothly over little rough surface without causing any trouble. 
d) Another important quality is carbon is self lubricating which means low friction. As temperature rises unlike any other metal carbon friction coefficient decreases making it suitable for using in rotating machinary.
e) Chemically carbon is stable and it's expansion is also negligible.

These are some reasons which make carbon as a best choice.

Why Carbon Brushes are split?

About Carbon Brushes:





Generally carbon brushes not used as single blocks. Normally two wafers are bonded with a cushion pad. Three wafers also seen in the industrial sector. Brush sizes and design and grades depends on many criteria and normally is matter of experts.

The splitting is mainly done to increase the contact points. Theories says that the number of contact point does not depend on brush cross sectional area. It is kind of fixed. Normally a carbon block has around 10 contact point regardless with its contact area. So Splitting carbon brushes increase the contact point. If we use two wafer carbon brush then there will almost 20 contact point available.

And also the increased cross resistance due to splitting helps in commutation which is the another good side of brush splitting.

What is Patina?


About Carbon Brushes:







Patina is also know as film or skin over DC motor commutator. It is mainly copper oxide that formed on a commutator surface as a result of reaction among copper, graphite, oxygen and other free particles in some range of temperature. Patina is a very thin film and can easily damaged.
Patina is very helpful in commutation, it makes commutation smooth. So during maintenance extra care should be taken to preserve patina.
Patina color
Normally in good condition patina formed all over the commutator evenly. And the color of patina can be slightly shinny, coppery brown to black. But keep in mind that the color of patina is not that important thing, the important thing is whether they are forming evenly or not.

Bad patina indicates some abnormality of the environment or the motor. Such as high humidity, presence of oil and grease particles, uneven commutator surface, uneven current distribution, low load operation, commutation problem, high resistance problem, raised mica, vibration etc.

Current Density in Carbon Brush

About Carbon Brushes:





Current density is normally expressed as amps per square cm or amps per square inch. Current density is simply the value of current that is passing through per unit area of carbon brush.
There are some points that effects the current density of carbon brush such as temperature, vibration, nature of operation continuous or intermittent, speed etc.
Current density in a carbon brush using in DC motor can be calculated with the following equation:
Current Density Equation
In Brush circuit contact area from Total number of brushes half brushes are used to carry in the current and half brushes are used to carry out the current.

For bottom angled brush the contact area is not just width X thickness but the contact area should taken into account. 

A carbon brush should not be operate in low current density. Low density operation is more dangerous than over density operation.

Finding fault histroy in Simoreg 6RA70 DC Drive

In SIMOREG 6RA70 DC drive there are built in options in the drive to generate various types of fault and store them in drive memory. 

For Diagnostic purpose when a fault occurred we need to see three things from drive. One is fault code or message. It give a overall idea about the fault. The second thing is the fault value. If we observe the drive manual under a certain fault there are some sub options identified by numbers. They are fault value. A fault value help up to be more specific about the fault. And as a maintenance engineer we should always keep an eye on how long the problem takes. The third thing is the occurrence time means when the problem occurred.

All these can be observed in a 6RA70 DC drive. Let see how. 

When a fault occurred it is probable that multiple problems can be occurred at a same time. In 6RA70 at best eight (8) these types of fault can be saved. Means it at the same time numbers of fault occurred then it can save up to eight (8) fault. 

Total eight(8) nos of fault history can be saved in it. Means eight faults from different time slot can be saved and in each time eight fault that occurred at the same time can be saved. When new fault occurred then the last one deleted.

The Fault code or fault value can be seen from the parameter p947 (r947) a read only parameter shows the fault code or message. In this parameter you see total of 64 index. First eight index is allotted for the first at a time occurred fault. Suppose only one fault occurred at a time then index 1 will be filled and other 7 index will be 0. 

The Fault value can be seen from r949 parameter. It is also a read only parameter. It holds the corresponding value for p947 ( r947) index. It has same nos of index like r947

And the Fault time can be seen from r049. It just got 8 index. 
Fault code, value and time

In index one current fault is stored if it is not acknowledged. Acknowledged fault moves to the below. From figure you see only 1,9,17,25,33,41,49,57 index are relevant .

It is a great feature of Simoreg 6RA70 drive. Proper using of fault code along with fault value save lots of time. It is a really helpful tool in industrial sector.

Add Ad Sense Advertisement after your Blog Post Title

First think before taking such step and be careful when doing this because Google doesn't allow customizing ad code. So any change in add code may make your ad-Sense ban.
But it's an easy thing to do. First select ad types and generate your code form your Ad-Sense account. Your Ad-Sense code will be something like as follow:


<script type="text/javascript"><!--
 google_ad_client = "ca-pub-Publisher-ID";
google_ad_host = "ca-pub-Publisher-ID"
/* medium */
 google_ad_slot = "slot number";
 google_ad_width = 300;
 google_ad_height = 250;
 //-->
 </script>
 <script type="text/javascript"
 src="URL of ad js file">
</script>

But to show advertisement right after blog post title you need to edit your Ad-Sense code.Change your ad-sense code as follow:


&lt;script type=&quot;text/javascript&quot;&gt;&lt;!--
google_ad_client = &quot;ca-pub-Publisher-ID&quot;;
google_ad_host = &quot;ca-pub-Publisher-ID&quot;;
/* medium */
google_ad_slot = &quot; slot number&quot;;
google_ad_width = 300;
google_ad_height = 250;
//--&gt;
&lt;/script&gt;
&lt;script type=&quot;text/javascript&quot;
src=&quot;URL of AD js file&quot;&gt;
&lt;/script&gt;

Change the < sign with &lt; 
Change the > sign with &gt;
Change "" with &quot;&quot;
Your modified code will be shown like above example. Do it carefully. Or you can do it using some simple program. There are some websites which also provide this type of facility.

Now the task is to place this code. 
Go to you code window from Design -> Edit HTML. Now using search pallet ( click ctrl+f ) find the following code <data:post.body/> and paste your modified code just above this code. Before doing this one important thing is don't forget to take backup copy before saving your modified code. 

Save your template and see the page preview. Another thing to remember that don't use more than three ad unit or you may face problem of not seeing ad instead seeing some blank space which can degrade your blog appearance.

How to add ad-sense advertisement in your blogger blog

Once you have an ad-sense account then you can easily create your ad-sense code and use them in any website or blog in which you have legal access. The easiest way to add advertise in your blogger blog is to add them from design mode. But it has some limitation. In this way you can’t add them anywhere you like. You can only add those as a gadget where you see  a gadget option. Normally Google gives the limitation to use only three ad unit in one page. So be careful because if you use more than three ad unit then it is probable that the excess unit will show as blank which may affect your blog appearance. 

In one way
Click on “Add a Gadget” from Design menu
From gadget window click on the “+” sign of Ad-sense tab and then configure which type of ad you want to add. Finish your task then it will show the element as “Ad-sense” in your design page. Now change the position of the element as you want. Save it and take a look. 
Addind Ad-Sense
 On another way after clicking add a gadget you can select HTML/JavaScript tab in lieu of AD-sense tab. But in this way you need to generate ad-sense code from your ad-sense account. Copy the code and paste it in the content. Save it.
Add Ad-Sense through Script
You will need these options because nowadays there are a lot of ad-sense designs available and you can customize them with more liveliness from your ad-sense account using the tool then you can generate ad-sense code and paste. It gives your ad a better look and feel. But from ad-sense tab (first option)  the customization is limited.

By this way you cannot add your advertisement after post title or in post body. Then you have to go through a little bit complex thing. Cause it’s a little bit different and need extra care. Any mistake can ban you. If you confident enough then you can see the following article How to add ad-sense advertisement after blog post title.
