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.

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.

Your benefits

Technologically leading

• Fewer components than in typical setups (no sinusoidal filter,

motor-integrated magnetic bearing controller), less wiring

• Reduced space requirements of blower system

• High efficiency due to perfectly matched system components

and most innovative drive technology

• No UPS needed in case of power failure

Reduced system costs

• Better price-performance-ratio and fast and easy installation due to new

system setup with fewer components

• Lower life-cycle costs (TCO) due to wear-free bearings and highly

efficient operation

• Easier supplier management as all componets from a single source

Reliable operation

• Extended condition monitoring for predictive maintenance due to

various system sensors

• Safe operation in case of power failure without battery or UPS

• Resistance to pressure fluctuations and air impurities and possibilities

for system adaption to process conditions

Quick support & service

• Extended condition monitoring and data logging for failure analysis

• Easy parameterization via one communication interface

• Easy diagnosis by means of one tool for drive and AMB

(locally and remote)

Fast time-to-market

• Fast blower design and commissioning due to pre-configured and

system-tested components (plug & play)

• Design and installation support by experienced supplier
