News from ATB Group


New production site in Wuhan, China

As of today, ATB Austria Antriebstechnik AG, Vienna is entering into a Joint Venture (JV) agreement with Wolong Electric Group Co. Ltd. for the purpose of the co-ownership of a motor manufacturing plant in Wuhan, China.

Following the creation of a new sales office in Shanghai at the beginning of 2013, ATB is adding another production facility to the group to further expand its business activities on the Asian continent. ATB therefore enters into a JV with Wolong Electric Group Co. Ltd., a company belonging to the same group of companies as ATB’s major shareholder Wolong Investment GmbH. The JV will be effective after approval by the Chinese authorities.

The JV involves the co-ownership of the company Wolong Electric Wuhan Co. Ltd. which will be renamed to ATB Wuhan (Motors) Co. Ltd. upon approval. ATB will then take over the management of the company, a production plant in Wuhan within the province Huwei.

This strategic extension of the ATB group serves to increase ATB’s market share and to provide a production platform for local manufacturing in China. It gives ATB the opportunity to enhance its position in the global market place. The new co-operation also further strengthens synergies between Wolong and ATB and constitutes therefore a win-win situation for both groups of companies.

Product innovation ISI - Integrated Simple Inverter

As a professional full-service provider of high-efficiency drives, ATB introduces the ISI (Integrated Simple Inverter), a new product for variable-speed applications on the market. Unique is the easy-to-use solution for a motor with integrated inverters that are connected to each other via a modular plug-in system. Based on extensive design and manufacturing expertise, this product solution was originally tailored specifically to the individual requirements in the sector of private and public swimming pool equipment. Precisely tuned algorithms and customized software ensure highly efficient workflows. The ISI system is characterized by a space-saving design of motor and inverter in a robust aluminum die-cast housing as well as its quick installation and  simple handling. The integrated inverter software is aligned to current and future engine technologies: from induction motors proven for decades, to state-of-the-art permanent magnet motors, to trend-setting reluctance motors. The programming is easy.

At Speck Pumps, the first user of the ISI system, the team is completely satisfied with the motor-inverter solution. "A user-friendly intuitive operation via a keyboard, easy reading on the comfort display as well as a variety of interfaces for different control options – one can hardly have more comfort at a pump! ", says Hermann Speck, CEO of Speck Pumps, praising the perfectly synchronized product. Due to its lean design, the total system ISI can be barely distinguished from a simple, conventionally built electric motor. A connection box, taking up no more space than the usual standard junction box, allows for easy replacement of existing engines. ISI also has variable connection options of the drive, which is achieved by means of flexible cable glands. ISI will be available on VSD IE2 level (Variable Speed ​​Drive IE2 level) in the power range 0.75 kW to 5.5 kW for protection class IP55 standard, and optionally in IP65.[1]

The development of the product ISI doesn’t end here by any means. The ISI system is being realized by ATB in two stages of development. Currently, it is available with an asynchronous motor in VSD IE2 level. In the second phase, ISI will also be available with a reluctance motor and thus up to efficiency class IE4 VSD level. The synchronous reluctance principle promises an extremely useful combination of easy handling and high efficiency, especially in a partial load range. ISI is ahead of the future and already meets the conditions for an optimal operation of systems with regards to energy efficiency 2020. The synchronous reluctance motor therefore provides a useful addition to the selection of tomorrow’s technologies. ATB ​​is proud that the Speck Pumps GmbH, with whom a long-standing and successful partnership exists, will also take this step together with ATB. Speck Pumps will be using the ISI version with reluctance motor as of the upcoming year.


[1] With respect to the VSD IE3 should be noted that standardization work concerning the future VSD efficiency levels of IE and their measurement provision for variable speed drives of all technologies is not yet finished in the IEC and CENELEC organizations and their related working groups.
