bearing designs, and improved conductors or superconducting
materials. [20]
What about motor repair versus replacement? Motors can be
rewound without losing performance when the repair is done
carefully (see Cao and Bradley, 2006).[18] However, an analysis
is advised regarding cost effectiveness of replacement of the
older, less efficient motor with a new, higher efficiency motor.
Moving beyond motors... Efforts have been underway, especially
in Europe, to move past just the motor and include the entire
drive system in a new standard: EN 50598. [5,30]

75 HP, TEFC, 1800 rpm motors [15]
In the United States, DOE is funding R&D, currently at $25
million, for development of Energy-Efficient Electric Motors: 13
projects have been identified. [11]

Additionally, the Advanced Manufacturing Office (AMO) within
DOE has initiated a Next Generation Electric Machines (NGEM)
program. It is an R&D effort leveraging recent technology advancements in power electronics and electric motors to develop
a new generation of energy efficient, high power density, high
speed, integrated medium voltage drive systems for diverse applications. Key enabling technologies being developed include:
wide bandgap devices, advanced magnetic materials, improved
insulation materials, aggressive cooling techniques, high speed

Figure 5. System limits of the extended product in accordance with
EN Standard 50598 (equal to IEC 61800-9). [5]
This quote from ABB summarizes the standard. [29]
EN 50598 is a three part standard looking at Ecodesign for
power drive systems and their driven applications.
*
EN 50598-1 of the standard (released December, 2014)
is titled "General requirements for setting energy efficiency standards for power driven equipment using the extended product
approach (EPA) and semi-analytic model (SAM)."
*
EN 50598-2, released in December, 2014, is titled
"Energy efficiency indicators for power drive systems and motor
starters."
*
EN 50598-3, released in March, 2015, is titled "Quantitative ecodesign approach through life cycle assessment including product category rules and the content of environmental
declarations."
The standard is being produced by CENELEC, the European
committee for electrotechnical standardization.
Understanding EN 50598-2: EN 50598-2 defines energy efficiency indicators ("IE" and "IES") for the complete drive module
(CDM) and the combination of the CDM and motor to form a
"power drive system" or PDS. The standard includes methodology to determine the CDM and PDS losses, assigning the IE and
IES values. This standard applies to motor driven equipment
from 0.12 to 1,000 kW (100 to 1,000 V).
In Summary... The significant "push" over the last 20 years has
resulted in several updated and new standards. This evolution
is expected to continue without abatement and to spread to the
emerging markets. In order to ensure product compliance and
to guide product development, it is imperative that manufacturers follow these developments closely and participate in their
development.
