Warranty, liability and support
We shall not be held liable for any information provided in this document.
We accept no liability for any damage or loss caused by the applications,
information, programs, planning data, or performance data described in this
example, irrespective of the legal basis for claims arising from such damage
or loss, unless liability is mandatory. For example, according to the product
liability law, in cases of malfeasance, gross negligence, due to endangerment
of life, body or health, due to assumption of a guarantee for a product's
characteristics of state, due to malicious concealment of a defect or due to
violation of basic contractual obligations. Any claims for damages caused by
violation of basic contractual obligations, however, shall be limited to the
foreseeable damage or loss which is typically envisaged in contracts unless
there has been malfeasance or gross negligence or unless liability is
mandatory due to endangerment of life, the body or health. This does not
entail a change in the burden of proof to your disadvantage.

MEPS
On one hand, considerable emphasis is placed on energy efficiency
to protect our environment. On the other hand, a higher energy
efficiency allows companies to improve their cost position,
therefore increasing their competitiveness.
Sustainably reducing energy usage
Regarding energy efficiency, the focus has been on industrial direct-on-line
(DOL) motors from a very early stage. This is because electric drives consume
70% of the electric energy in the industry. As a consequence, electric drives
represent a huge potential when it comes to boosting efficiency. Many
countries have already created a legal framework to reduce energy
consumption in their industrial landscape – and to achieve the environmental
goals that have been set.
Standards
Initially, global standards were defined to achieve this, for instance IEC
60034-30-1 and NEMA MG1. The standards were either taken over – or
transitioned into minimum legal efficiency requirements. The term used
around the globe for these minimum efficiencies is MEPS: Minimum Energy
Performance Standards.

Profit from MEPS
Companies operating plants especially profit from MEPS regulations as these
help them to boost their productivity. For instance, for a 110kW motor, the
energy costs represent up to 99% of the overall lifecycle costs. As a
consequence, by increasing the efficiency of a motor, the energy
consumption can be significantly reduced – and along with it, the associated
costs. Companies operating plants can sustainably benefit when investing in
energy efficiency.
Tools
Tools are available that can be used to define when it makes sense to invest in
energy efficient motors:
SIMOTICS EE Comparator
The efficiency of IE4 motors is 14% higher than for IE1. Operating costs can
be reduced with a high efficiency. A payback calculation always makes sense
in order to select the most cost-effective motor for line operation. Every
country has its own specific MEPS requirements. An overview of these
requirements is listed below, but can also be simply viewed using the
SIMOTICS EE-COMPARATOR App.

SinaSave
Answers to questions, such as "What is the payback time when investing in a
more efficient motor?", "Does it make sense to use a variable-speed drive or a
DOL motor for my applications?", "How does the energy efficiency class of a
motor impact the cost effectiveness of the drive system?", can be found in the
web-based SinaSave tool. Based on individual operating characteristics as
well
as
system-specific
parameters,
SinaSave
calculates
the
energy
requirements of various drive products and systems, which are then
compared with one another. Further, SinaSave tells you the payback time
when investing in an energy-efficient drive solution. Based on the investment
and operating costs as well as the energy-saving potential, this tool calculates
the expected payback time. Not only this, it also provides fast and
straightforward help for decision-making when it comes to financially
assessing the investment in energy-efficient products.
You can find SinaSave here: siemens.de/sinasave.
Low-voltage motors for every requirement
SIMOTICS low-voltage motors are available in a power range from 0.09 kW to
3500 kW – to address many efficiency standards worldwide. We can offer you
the optimum solution for every specific requirement: in addition to energy
efficient motors in compliance with specific standards, explosion-protected
motors for the highest safety standards, along with motors for specific sectors
and
customers.
Employing
state-of-the-art
product
and
production
technologies, these motors are especially compact – and in many cases have
the same dimensions irrespective of the particular efficiency class.
