Decades of experience
For decades, Baumüller has planned,
developed, produced, and implemented drive
systems and drive solutions in cooperation
with customers. The reliability, ruggedness,
and high level of availability of the
drive systems have made Baumüller
a partner to machine builders, not only
in the plastic industry.
Apart from the proven DC drives for extrusion,
Baumüller, as a leader of this industry,
has made three-phase AC technology - synchronous
and asynchronous - available for drives
on extruders.

Extrusion
How to slash
running costs
The new three-phase AC drives for extrusion
are a sensible investment in the future.
The Baumüller three-phase AC system:
- is maintenance-free
- improves the total efficiency of the
drive systems
- has virtually no reactive-power demand
High applications for intensive maintenance
and high power consumption is not necessary. |
 |
Baumüller motors – high power
density with three-phase AC technology
The three-phase AC motors are internally ventilated
and have IP23 protection. That means there is
an extremely high power density available for
the drive. Consequently a DC motor can easily
be replaced by a three-phase AC motor, retaining
shaft height and unit volume. Higher degrees of
protection can be implemented depending on the
requirements.
Extruder drives from Baumüller - and the
benefit is yours
Baumüller converters:
- compact
- high power density
- easy to put into operation due to graphic
user interface
- brief power failures are jumpered
- all standard field bus systems are available
Baumüller drive systems –three-phase
AC technology for extrusion
- constant torque from zero speed to rated speed
- high torque even at low speeds over long
periods
- maintenance-free – no brushes or collectors
- improved efficiency - 3-6% compared with
DC drive
- practically no reactive-power demand
- high degree of protection (IP54) possible
without much effort
- very high speed precision
- excellent current/torque ratio
- synchronous technology offers even better
efficiency.

Injection molding
As a drive system manufacturer Baumüller has been pioneering
in the field of injection molding machines for plastics as
well.
With injection molding machines the hydraulic system is partially
or entirely re-placed by electric drive systems. New standards
in the construction of plastics processing machines are now
made possible by Baumüller due to innovative drive technology
which takes into account and integrates the special requirements
for this type of machine. Baumüller always succeeded
in developing drives with a very high power density and a
very large dynamic range. In addition, the drive solutions
provided by Baumüller adapt to the requirements of the
machine’s mechanical system, so it is the machine that
dictates motor design.
With electric
drives for the screw
- higher precision is achieved in production
- the parts made are easier to reproduce
- machine output is increased so its productivity
is higher
- machine energy consumption is considerably reduced
|
|
With fully electronic injection molding machines
- machine energy consumption is reduced further still
- the machine’s intrinsic noise is reduced
- there is no longer any hydraulic fluid on the machine

The Baumüller components for injection molding to perfection
Watercooled
motors:
- high power density
- high degree of protection: IP 65
- very compact
- low noise because there is
no need for a fan unit
- place of installation irrespective of the
direct ambient conditions
- simple, local heat dissipation
- very dynamic
- practically maintenance-free
- rugged
- large ranges of speed adjustment
- synchronous and asynchronous technology
|
Watercooled converters:
- compact design to save space
in the control cabinet
- no additional air-conditioning units required
- high power density
- easy to put into operation due to
graphic user interface
- brief power failures are jumpered
- all standard field bus systems are available

Blow molding
| The blow molding
process is extremely demanding for the plastic processing
machines, and especially for the drive system. Complex
molds have to be made with absolute repeatability and
precision to within tenths of a millimeter.
With Baumüller drive systems you can realize a
very wide range of machine concepts – profitably
and in line with state of the art automation.
With the fully electric blow molding machine using Baumüller
drive systems you work more precisely and more profitably
than with fully hydraulic machines. Less waste, less
noise, and less energy consumption – those are
the advantages of the electric drive systems for blow
molding machines.

Handling
Automation solutions and handling systems for plastic production
| Apart from the drive systems
for extrusion, injection molding, and blow molding,
Baumüller solves all the problems associated with
drives in material handling, post-processing, and down-stream
processing.
For the entire plastic processing industry Baumüller
offers planning and design, handling and automation
systems, from the motor, converter, and control engineering,
to control systems and software solutions for motion
functions. Consequently, the drive solutions for film
extrusion, film winding, and film printing, for instance,
are all from a single source.
|
Decentralized intelligence
 |
With the automation concept
b maXX you can modularize your machine systematically.
b maXX puts intelligence into your drive. As a result
you achieve control functionality in the converter and
time-critical functions which are processed for converters
on shaft generators.
Using b maXX, complex technological drive functions
in the machine, e.g. winder, dancer roll, and register
control, or electronic cam, can be handled in a user-friendly
manner.
