Identify potential energy and cost savings through electric motor upgrades with Regal’s free calculator app

by Brianna Crandall — March 2, 2018 — Regal Beloit Corporation, a US-based manufacturer of electric motors, electrical motion controls, power generation and power transmission components used throughout the world, announced it has broadened the capabilities of its Browning Toolbox Technician app with the addition of a motor efficiency calculator that enables comparisons between various generations of integral horsepower electric motors.

The Toolbox Technician app is a free toolset for heating, ventilation and air-conditioning (HVAC) contractors and maintenance professionals that features calculation and conversion tools, a GPS-enabled distributor locator, and informative reference, installation and troubleshooting guides for everything from bearings to v-belts.

The US Department of Energy (DOE) publishes an example in its When to Purchase Premium Efficiency Motors publication (DOE/GO-102012-3743) illustrating that, over a 10-year operating period, for a 75-HP standard efficiency motor, 98% of the cost of ownership is attributed to energy and maintenance cost. The DOE also states in this publication, “Even a small improvement in motor operating efficiency can produce significant energy and cost savings, and provide a rapid return on investment.”

The new motor efficiency calculator helps users to identify potential energy efficiency gains by selecting operational parameters, whereupon the calculator automatically displays projected return-on-investment (ROI).

According to Don Sullivan, director of Marketing, HVAC and Belt Drives, Regal Beloit America:

Recognizing the financial impact that can be realized through energy reductions, this tool will help facility managers, building owners and those tasked with managing energy consumption to identify ways to lower that consumption and save money. Motor upgrades present a great opportunity to reduce energy, and this calculator will help users compare efficiencies to make informed purchasing decisions.

The calculator allows users to input the published efficiency from the motor nameplate or to use a default EPAct rating. The app will automatically compare the efficiency of the motor to a NEMA Premium motor of the same horsepower and display projected annual energy savings.

Other adjustable parameters include motor HP, number of units, days of operation per week, hours per day, and expected motor life. By inputting premium efficiency motor cost and adjusting these parameters, users can easily calculate annual cost savings, total cost of ownership (TCO) and projected payback window.

Regal also added a retrofit audit feature to the Toolbox Technician app in early 2017.
