Nuremberg.
Nuremberg-based drive manufacturer Baumüller and Sensor-Technik Wiedemann GmbH (STW) from Kaufbeuren have collaborated closely on a joint project to develop a mobile diesel-electric machine.
The recently signed cooperation agreement signals the expansion of the joint development and production operations in the field of hybrid drive technology.

The mobile diesel-electric machine is part of a powerMELA® hybrid drive system designed to be used in, for example, agricultural and construction machinery or commercial vehicles.
It consists of a generator which is driven by a diesel engine and generates a direct voltage of 745 volts via an integrated rectifier.
The resulting power can then be made available to a rotation-independent DC power supply network.

Other electrical machines then function as motors to drive the wheels from this power system either directly or via gears and can be easily controlled and regulated via a CAN bus system. The power supply network also permits the electrical operation of add-on units and accessories.
Excess energy can be stored in a battery.
Modified DS-series servo motors from Baumüller are used for the generator, the main drives and the auxiliary drives.
Because of their high power density and excellent efficiency, these motors are particularly suitable for applications which call for high energy efficiency.

“The demand for powerful, efficient hybrid drives for mobile machines is growing enormously. Thanks to our technology partnership with Baumüller we can call on the expertise of a drive manufacturer whose electric motors have been established in the market for decades. This enabled us to create synergies and develop a sustainable solution whose market prospects we regard as excellent,” says Wolfgang Wiedemann, CEO of Sensor-Technik Wiedemann, in describing the motivation for the joint R&D work.

For Nuremberg-based drive and automation specialist Baumüller the collaboration with STW means the development of new markets:
“In classic industrial applications the system concept and the replacement of hydraulic elements to improve the energy balance are playing an increasingly important role. Our knowledge in this field complements STW’s expertise as a system integrator in the field of sensor and control technology, thereby opening up new opportunities in the technical design of the drive system for both sides,” says Andreas Baumüller, Chief Technical Officer at Baumüller Holding GmbH & Co. KG.

“Because of the high energy costs and increasing environmental awareness there will be no way round hybrid drive concepts in future, particularly with regards to mobile machines. We are therefore convinced that the powerMELA® project and the cooperation with STW represent an important step towards gaining a lasting foothold in this market of the future,” continues Baumüller.

Perfect duo

Baumüller and ZAE develop high-efficiency food-safe geared motor


Nuremberg.
Drive manufacturers Baumüller and ZAE-AntriebsSysteme GmbH & Co. KG have jointly developed a two-stage bevel helical gear unit with integrated encoder-less permanent-magnet synchronous motor which achieves efficiencies of up to 90 per cent.
The geared motor is designed as attachable version and its surface finish makes it suitable for sterile applications, for example in the food, beverages and pharmaceutical industries.

The drive system is based on a standard Baumüller DSC-series servo motor from which a motor/gearbox combination was derived.
The motor was then electrically and mechanically optimised in the process.
A special winding system permits the optimum system design, and a special bearing concept enables the two-stage bevel helical gear unit to be integrated.
The gear unit was developed by ZAE and delivers efficiencies of up to 90 percent in combination with the integrated synchronous motor.

The robust construction and modern design simplify the fitting of the drive system which was developed as an attachable version.
It is attached onto the machine shaft as a unit and is generally also braced by means of a torque support.

The alignment of the drive is user-definable in 90° increments, enabling the motor/drive combination to be incorporated ideally in the machine.
Furthermore, the drive is suitable for sterile applications.
Thanks to the integrated connection system, its surface finish and the lack of “dirt traps” it is easy to clean and it is difficult for germs to collect.
On request, the drive is also available with special coatings for the food industry.

Since the motor/gearbox combination achieves efficiencies of up to 90 per cent and the surface temperature does not exceed 75° Celsius even at full power, cooling fins and fans are superfluous.
The drives are also practically maintenance-free.
The lubricant used (the user can choose between H1 and H2) ensures that an oil change is only necessary after well over 20,000 operating hours.
Since an encoder is not used, the system is considerably less susceptible to faults.

The technical innovations are reflected in the reduced life cycle costs.
Lower energy consumption, low maintenance costs and minimal susceptibility to faults mean that the higher costs resulting from the slightly higher purchase price are quickly balanced out.
Furthermore, savings can be achieved because the drive system has large usable operating ranges and the number of motor and transmission ratio variants needed is reduced.

The motor/gearbox solution was developed to series maturity by Baumüller and ZAE in just one year. If required, the motors are also available in the same design with an encoder or holding brake.
Work is in progress on expanding the solution into a geared motor series
