The most simple & innovative magnetic

bearing solution

The integration of magnetic bearing technology has never

been so easy thanks to KEBAS’s new magnetic bearing drive

system. The radically reduced number of system compo

nents leads to a highly compact, cost-efficient and easy

to-install solution.

// Motor-integrated magnetic bearing controller

// No sinusoidal filter

// VFD-integrated power supply for magnetic bearings

// No UPS / battery

// Only one PLC interface

// No air cooling fans for magnetic bearings

// Less wiring

The sensor technology of the magnetic bearing in the motor

enables extensive condition monitoring of the drive unit and

also of the process. The current condition of the machine is

available at all times and this information is transmitted to

the machine control via the central Ethernet-based field bus.

System and process optimization is thus possible at any time.

New magnetic bearing drive system for turbo blowers

The increasing importance of turbo blower’s life cycle

costs and the technological limits of turbo systems with

airfoil bearings lead to a significant trend towards mag

netic bearing systems.

Based on KEBA’s track record with an installed base of

more than 800 magnetic bearing drive systems (waste

water aeration, yeast production) and the unique tech

nology portfolio, KEBA launches the most compact and

efficient magnetic bearing drive system for turbo blower

applications for the power range of 150 – 300 kW

(200 – 400 hp). All components of the drive and bearing

train are from a single source.

Fast and safe system integration

Our modular drive controllers can be perfectly integrated into the KEBA or a

third-party automation system.

Flexible communication

“One Drive fits all” – Standardized interfaces such as EtherCAT, PROFINET or

CANopen allow uniform drive technology and constant motion quality even

when using different controllers.

Advanced commissioning tools

Tools that have been tried and tested over many years ensure perfect commissioning

with their many assistant functions. These include guided commissioning, a real-time

oscilloscope or frequency response analysis for precise detection and compensation

of mechanical deficiencies.

Open motor interface

In addition to the extensive KEBA motor program, our drive controllers with their

multi-encoder interface and various control models are open for special or third-party

motors. The automatic user-guided motor identification optimizes all control parameters.

Scaleable Safe Motion Packages

All drive controllers are already equipped with the STO function as standard.

Additional safety functions and packages ensure compliance with applicable regulations,

depending on the application. Safe motion monitoring can be activated and parameterized

via I/O or FSoE fieldbus communication.

Digital control technology

Control technology makes the difference at KEBA.

A sophisticated control structure and predictive pre-controls allow the

greatest possible dynamics with the highest level of accuracy.

Mechanical inadequacies are corrected online using adaptive processes,

and mechanical oscillations or vibrations are suppressed or filtered out.

Inadequacies in the mechanical transmission path can include encoder

errors, friction and cogging torques, resonance frequencies or asymmetries

in gantry applications.

A variety of analysis and compensation functions are available in our drive

controllers for this purpose.

Autotuning for easy commissioning identifies the machine mechanics and

parameterizes the control loops quickly and reliably.

To reduce downtimes, the drive system and the coupled mechanics are

constantly monitored. Defects are diagnosed quickly and wear is diagnosed

in advance. The internal evaluation of all data ensures fast analyses, only the

results are transmitted to the factory automation in real time.

Drive solutions that move

KEBA servo controllers offer high dynamics and precision for a wide

range of applications in industrial automation. Our focus is on

comprehensive support for system integration and the selection of

suitable drive solutions.

For simple and efficient integration into existing automation solutions

solutions, various bus systems including EtherCAT, Profinet, CAN and a

large number of analog and digital encoders are supported.

Furthermore, KEBA servo drives can be easily integrated into existing

safety solutions; integrated Safe Motion solutions up to SIL 3.

PLe and CAT 4 offer flexible options for this.

Built into axis controller as standard

KeDrive D3 comes with STO (SIL3. PLe, Kat 4) and SBC (SIL2. PLd, Kat 3) as stan

dard. This makes the drive system suitable for applications with high demands on

safety, for example in presses or for the handling of suspended loads.

SafeMotion in axis controller (option)

The axis controller safely monitors the motion in compliance with EN / IEC 61508 and

EN / ISO 13849. Available safety functions include SS1. SS2. SOS, SLS, SLI, SDI and

SLP with up to SIL3. PL e, Cat 4. With the high safety levels that can be achieved,

consistency, which can be verified for series processes.

Highlights

Simplicity

We simplify your automation to give you more time for what matters.

Simple installation

Installation is much less complex than for conventional solutions: firstly because of the

small number of components needed, and secondly because these components can

be quickly connected using a simple connection system.
