Developed at the site ATB Schorch the new transnorm motor has been thermally optimized using state-of-the-art CFD software (Computational Fluid Dynamics) and provides high power reserves. The ATB design team designed a special rib geometry and optimized the flow pattern in the light of aerodynamic rules, thereby achieving a maximum of heat transfer (see figure 1). Furthermore, a design-perfected internal fan and an axial external fan lead to an efficient transfer of internal heat loss to the external cooling circuit of the machine.

Exceptional is also the ratio of low weight to high performance. By using modular accessories the new transnorm motor can easily and quickly be tailored to customers' special requirements. It is also suitable for the inverter operation. With its compact design, this engine series is also ideally suited for retrofit.

A corresponding Ex version of this series is currently being developed.

Typical applications for this engine series are:

- pumps,
- compressors,
- ventilators,
- blowers,
- mills and granulators

in a number of industries.
