How can an electric propulsion system save 1,000,000 tons of fuel and contribute to a more sustainable future? How does a cable tie developed in 1958 contribute to the latest Mars expedition? And what does the monitoring of industrial motors have in common with a conventional fitness tracker? Here, we take you through some of the most interesting facts and trivia of our company’s portfolio – with short, easy to understand explanations.
Millions of motors for heating, ventilation, and air-conditioning (HVAC) applications have been in place for decades. However, regulations globally continue to tighten the energy efficiency requirements for fan, pump and compressor systems. By incorporating new technologies, ABB’s EC Titanium motor system achieves the highest energy efficiency standard, IE5, while using sustainable materials.
To achieve this highest efficiency the EC Titanium combines two motor technologies - synchronous reluctance and permanent magnet - while integrating a variable speed drive. By using non-rare earth material for magnets the environmental impact associated with rare-earth magnetic material is reduced. In an EC Titanium the stator generates a magnetic field more efficiently with less mechanical loss. The unique design, in which the magnetic material is embedded into a synchronous rotor, enables the motor to reach a higher power factor, drawing less current than other, similarly sized motors, leading to lower energy consumption, and to lower electricity bills. An EC Titanium motor also requires a smaller drive than similarly sized motors, which reduces the footprint and weight of the entire system. Additionally, the integrated motor/drive solution saves considerable control panel space and reduces wiring costs.
By replacing just one induction motor with an EC Titanium unit, a pharmaceutical packaging company was able to reduce its energy consumption by more than 10 kWh per day. That 20 percent reduction results in cost savings of $43.30 per month, or $520 per year, on the electrical bill. A complete return on investment can be reached in 18 to 24 months.
Electric motors consume more than 45 percent of the world’s electricity and as much as 70 percent in non-residential applications. Therefore, the adoption of high-efficiency motors and variable speed drives are important steps toward achieving significant energy efficiency improvements in industry and infrastructure. Replacing 80 percent of motors currently in operation with newer designs achieving IE5 efficiency levels would save more than 160 terawatt-hours of electricity each year - greater than the annual power consumption of Poland - and cut total global electricity consumption by as much as 10 percent.
