Free slide rule based energy savings calculator from ABB
14 September 2010
ABB has designed a pocket-size slide rule that shows end-users the savings they can achieve by changing a direct-on-line motor to variable speed drive control. Using the data on one side, the user first selects the power rating of the direct-on-line motor. A window reveals the typical running costs and kWh if the motor is operated at full speed. As an added twist, the slide rule also equates the energy consumption to the equivalent number of high efficiency light bulbs.
By then turning the slide rule over, the user can see the effect of applying a variable speed drive to the application.
Users can quickly compare energy consumption and cost between two applications; the first a motor running at full speed with no damper or throttle, the second a motor being controlled by a variable speed drive with 20 percent speed reduction. By selecting the power rating of the motor, users can compare the cost and KWh usage between the two applications based on running the motor for anything between 8 hours per day over a five day week, up to continual 24 hour usage over a whole year.
To order your free slide rule, email your contact and address details to energy@gb.abb.com or call 07000 374837 and leave your contact details.
ABB has also launched a free energy calculator application (App) for the Apple iPhone, iPad and iPod. The App allows end-users to calculate the energy savings they can achieve by installing variable speed drives to control motors and make quick comparisons between motors controlled by variable speed drives and motors running direct-on-line without any speed control device. Users simply select their industry and the operating duty profile; the voltage, phase and motor power rating; running hours; and electricity cost. The app then estimates how much CO2, energy and costs can be saved by installing an ABB drive to control the application.
Once all the parameters have been applied and the savings worked out, the App displays a picture of the most suitable drive for the user’s application. Simply click on the picture on the top half of the screen and a product summary will be displayed. The end-user can then place an enquiry or request more information.
