The Environmental Impact of Variable Speed Drives: Reducing Carbon  Footprint

As the world shifts towards more sustainable energy solutions, electric motors have become a central focus in reducing carbon  footprints. With the increasing adoption of electric vehicles (EVs) and  other electric systems, understanding their environmental  impact is crucial.

Recent studies, such as those published by the U.S. Environmental  Protection Agency, highlight the benefits of electric motors in  lowering CO2 emissions compared to traditional gasoline engines.  electric motors are not only more energy-efficient but also offer  significant reductions in greenhouse gas emissions, especially when  powered by renewable energy sources.

However, the production of electric motors does pose some  environmental challenges. The extraction of minerals required for  battery production, such as lithium and cobalt, can lead to significant  ecological disturbances. It’s essential to balance these impacts with  the long-term benefits of reduced emissions.

Joliet Technologies is committed to enhancing efficiency and  reducing costs with our high-quality, customized drive systems and  control panels. Our Variable Frequency Drive Systems provide a cost-effective method to match driven speed to load demands, offering a  state-of-the-art opportunity to reduce operating costs and improve  overall productivity.

In commercial and industrial applications, electric motors are essential for a wide range of machinery and equipment. The main methods for starting, running, and stopping these motors include direct-on-line (DOL) starters, star-delta starters, auto-transformer starters, soft starters, and variable frequency drives (VFDs). Here’s an overview of each method along with their advantages and disadvantages:

Direct-On-Line (DOL) Starters

Starting Method: The motor is connected directly to the power supply, allowing full voltage to be applied to the motor terminals.

Advantages:

• Simplicity: Easy to install and operate.
• Cost-effective: Low initial cost.
• Full Torque: Provides full starting torque.

Disadvantages:

• High Inrush Current: Causes a large surge in current, which can affect the power network and reduce the motor’s lifespan.
• Mechanical Stress: Sudden application of full voltage can cause mechanical stress on the motor and the driven equipment.

Star-Delta Starters

Starting Method: The motor initially starts in a star (Y) configuration, reducing the voltage and current. After a brief period, it switches to a delta (Δ) configuration for normal operation.

Advantages:

• Reduced Starting Current: Lower inrush current compared to DOL.
• Less Mechanical Stress: Gradual increase in torque reduces mechanical stress.

Disadvantages:

• Complexity: More complex than DOL, requiring additional components and wiring.
• Torque Dip: Temporary reduction in torque during the transition from star […]
  

Variable speed drives (VSDs) are devices that control the speed of an electric motor by adjusting the frequency of the electrical current that it receives. This allows for much more precise control of motor speed than is possible with traditional methods such as throttling the motor's input voltage.

Today at approx. 1:03pm CST we sent about 30 old Blog posts to our email list. This was a mistake and we are sorry.

We updated our RSS Feed to include older posts and our email broadcast software perceived that the older posts were new posts and sent them to everyone.

Once again, we apologize.

Welcome to the new and improved Joliet Technologies website. This is the look of our new site.

We have converted it to a responsive site design, which means it will be viewable on all devices and the functionality and content will remain the same whatever device you are viewing it on.
It has always been our goal to have the user experience be the best possible on our website and hopefully this new design will do just that. Our new user interface allows you, in most cases and on most devices, to navigate to any page on our site with just one click.

Also we have increased the security of our site by switching to https, so whenever you are on our site anything you do is encrypted. Your connection to https://joliettech.com is encrypted with 256-bit encryption & the identity has been verified by COMODO RSA Domain Validation Secure Server CA.

All the content on our site […]

We have completed the process of re-designing our website. This will be the new look of our new site.

We have converted it to a responsive site, which means it will be viewable on all devices and the functionality will remain the same whatever device you are viewing it on.

Also we have increased the security of our site by switching to https, so whenever you are on our site anything you do is encrypted.

All the content on our site should remain the same, some pages may be updated to reflect the current status of our company and our products and services.

If you have any questions and/or comments, please feel free to contact us directly at info@joliettech.com.

This blog is being presented by Joliet Technologies, L.L.C..

In addition to our regular website, we felt we needed a more casual place to air our views and feelings about what we do and the industry we are in. As you can see this is a very simple website.

If you have done any research at all into variable speed drives and variable frequency drives and controls, you probably have come across our website. It is our goal to provide the information you need to make intelligent decisions regarding variable speed drives and controls you use in your facilities.

It is our plan to post to this blog at least twice a month. The posts will be on a wide range of subjects. From information about our company and people that work here, to posts regarding our products and services.
