Depending on the industry, environment
and requirements of any given application,
there are many different methods of
transferring power from main supply to
machine. But no matter what the layout of
the drivetrain, there will always be some
solutions that offer smoother integration
and better efficiency than others. Bauer
supplies electro-mechanical application
solutions that guarantee every component
is hand-picked for the application, and
integrated as efficiently as possible.
Energy efficiency is a hot topic across every industry at the moment, but
without fully understanding all the components within the drivetrain,
only a fraction of the potential savings can be realised. Throughout the
drivetrain the potential energy savings are distributed via the ZVEI model:
10% via improved efficiency of the motor
30% via electronic speed regulation
60% via optimisation of the mechanical system
This highlights the fact that, while the current focus on energy
efficient motors is important, it’s even more important that engineers
don’t lose sight of the other areas where improvements can be made.
Bauer supplies electro-mechanical application solutions which
are committed to delivering the best solution possible for any given
application; by maximising the savings potential across each of the three
fields listed above. This means long-term reliability, low maintenance
costs and the best energy efficiency possible. Bauer’s approach to
optimisation is to adapt and simplify every aspect of the drivetrain —
ensuring that it integrates seamlessly with the machine.

Motors - 10% of potential saving
Recent technological advances in motor design have allowed
manufacturers to deliver radical improvements in energy efficiency.
Coupled with the recent IE2 and IE3 regulation — and the future IE4
regulations — this means that most applications are already benefitting
from improved electrical efficiency. In fact, a recent comparison test
of a standard IE2 asynchronous motor and a Bauer IE4 super premium
efficiency motor showed energy savings of over 40% are possible.
Not only does Bauer already conform to IE2 and IE3 classification,
it is also leading the way in new IE4 technology. All of the company’s
motor competencies — from design to manufacture — are maintained
in-house, which gives it autonomy over the quality of the product that
goes into its drivetrain packages. It offers a full complement of products
for all the energy classes, which means that there is a wealth of choice for
Speed Control - 30% of potential saving
Using a speed control device to monitor the required output of the
motor and regulate its energy use accordingly is well-known, quick and
simple way of increasing the efficiency of a system. Depending on the
requirements of the application, there are many different control and
monitoring concepts which may offer the best combination of cost and
efficiency. Bauer has developed relationships with many of the leading
manufacturers of speed control solutions to work hand-in-hand with its
products to maximise the efficiency of its systems.

Mechanical Optimisation - 60% of potential saving
While motor efficiency and speed control currently enjoy the
majority of media coverage, the fact is that mechanical optimisation
accounts for the majority of potential savings in most existing drivetrain
solutions. In fact, the opportunities are so vast that Bauer has split
it into two further sub-categories: Gear Technologies and Drivetrain
Bauer has been manufacturing Gear Technologies since 1927,
throughout these nearly 90 years it has always strived to offer the most
efficient and reliable solutions possible. To best service this aim it has
developed a standard, modular gear program as well as a custom design
and manufacturing service.
Modular models include the helical BG Series, parallel shaft BF
Series, bevel BK Series and worm drive BS Series; each series includes
low torque products (<100NM) to avoid unnecessary oversizing. The
range also includes application specific models — including the world’s
first modular stainless steel IE4 permanent magnetic synchronous geared
motor for the food and beverage industry complimenting the already
successful Aseptic™ range — offering unique features and capabilities
designed for the special requirements of differing environments.
Not only does Bauer already conform to IE2 and IE3 classification, it is also leading the way in new IE4 technology.
Each product is specified by application experts, with the help of
Bauer’s technical centre, to optimise for the specific application in terms
of energy-efficiency, smoothness, noise, impact-resistance and other
attributes. Where custom solutions are required, Bauer is able to provide
the shortest time to market possible thanks to continued investment in its
rapid prototyping capabilities.
Drivetrain optimisation is the last piece of the puzzle, but no less
important than the considerations that have come before it. Once each
aspect of the drivetrain has been specified, it must then be integrated into
the machine with as much efficiency as possible. This requires an in-depth
understanding of the drivetrain as well as the specific demands of a
given industry, which is why Bauer has a team of application experts who
specialise in different industries.
Bauer has developed relationships with many of the leading manufacturers of speed control solutions to work hand-in-hand with its products, maximizing the efficiency of its solutions.
Simple installation solutions, such as gearing that takes over the
bearing functions, thus reducing the number of components, can offer
improvements in efficiency that are equivalent to the step-up between an
IE1 and an IE4 motor in the same drivetrain. As part of Altra Industrial
Motion, Bauer is also able to work closely with the Altra Coupling
division, which includes brands such as Bibby, Huco and Ameridrives,
to specify coupling solutions which integrate the drivetrain with minimal
Thanks to its completely modular design, Bauer’s standard product
range offers thousands of potential drivetrain packages while, for more
specialized applications, the Bauer Specialist Serial Demand service can
build a completely custom design which is integrated into the machine
from the ground up. Its engineers work to maximise the potential energy
savings at every stage of specification and installation to deliver the best
possible solution for each individual application.
