A more systematic approach to energy efficiency

Siemens suggests that efforts to improve efficiency need to examine complete drive systems from one end to the other. Improving just the motor may not yield the largest improvements. Video: Siemens’ Michael Young offers an overview of the systematic approach.

Michael Young, division marketing programs manager for Siemens Drive Technologies division, offers an overview of evaluating energy efficiency system wide.



Identify, evaluate, improve: this three-step circular process summarizes Siemens approach to energy efficiency improvement programs, both for users’ internally driven efforts and as consultants. When applied to drive systems, the company contends that looking at only one component of a drive train in an application will yield only a partial result. Getting the biggest improvement may involve multiple elements since the stack-up of components robs overall efficiency.

For example, if a motor is connected to a gearbox via a flexible coupling, and the output of the gearbox is connected to the load with v-belts, any efficiency effort that does not consider all of these elements will fall short of delivering the maximum possible improvement. If the gearbox is of an old design that is at best, 75% efficient and the v-belts are glazed and not properly tensioned, adding a higher efficiency motor while leaving poorer performing components in place will not generate the highest return on investment. Reexamining the other elements of the system and beginning with the poorest performers will be a better approach.

Siemens is matching this strategy with its extensive portfolio of electrical and mechanical power transmission equipment. Given that it can provide motors, drives, gearboxes, couplings, and other components, Siemens has positioned itself as a consultant that can take a highly systematic approach.

Part of that offering includes a series of websites, including applications that allow users to calculate the overall efficiency of various parts of a power train application:

Annual Salary Survey

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
