Baldor has released a powerful new software estimating tool that enables users to evaluate the energy efficiency of electric motors and variable speed drives.
Known as BE$T, the Baldor Energy Savings Tool can be downloaded free from the company’s website.
The software analyses the efficiency and annual electricity usage of users’ existing motors, and calculates the cost savings that can be achieved by replacing them with equivalent higher efficiency models.
Built-in motor performance and pricing information enables the software to suggest optimum replacements and to estimate the investment payback period.
BE$T will prove especially useful to electrical engineers and maintenance personnel wishing to implement a comprehensive site-wide motor management strategy, or to simply compare the costs of a motor rewind against those of a replacement motor.
The software is also helpful to anyone charged with conducting an energy audit of their company.
Baldor’s BE$T program runs on any standard PC and is very easy to use. Data can either be input from the computer’s keyboard or imported from a Microsoft Excel file - both methods employ drop-down menus and are backed by extensive built-in help.
A single screen is used for setting all preferences and global project data, such as local currency, electricity costs, supply frequency and default motor load.
The results are available immediately – simply clicking on the Instant Cost Calculation button will show the amount of energy being used by the existing motor, together with the amount that would be used by comparable Baldor Standard-E (IEC IE2 rated or NEMA ‘Energy Efficient’) and Super-E (IEC IE3 or NEMA ‘Premium Efficient’) models. The results screen also shows the purchase cost of the motors and the payback period, and provides a direct link to a full motor specification. A built-in report writer function facilitates the creation of a simple summary or detailed report, with an export feature allowing the results to be output to an Excel file for further analysis or archiving.
One especially powerful feature of BE$T is that it handles What-If? scenarios, enabling users to simplify and accelerate iterative calculations. For example, significant energy and cost-savings can often be obtained by adding a variable speed drive to an existing electric motor, especially if its load has a variable torque demand, as is often the case with pumps, fans and blowers.
BE$T provides Excel templates for various gears, pumps and fans, and allows users to ascertain the financial benefit of adding speed control to their particular application very easily and quickly.
Baldor’s BE$T energy estimating tool runs under Microsoft Windows on any standard PC. Microsoft Excel 97 or above is recommended for spreadsheet data import and export functions.
