Performance & Technology

With their highly optimized PSM design, direct cooling, and modular construction, the DEF S-One models achieve exceptional power density. The machines have been tested for continuous operation and peak loads, offering true long-term stability. On request, they can also be supplied with an inverter, hydraulics, or control unit as a complete system.

Reliable in all areas of application

The DEF S-One has a modular design and can be seamlessly adapted to various requirements, from single units to system solutions with inverters and hydraulic units. The motors in the S series have successfully passed the ISO 16750 tests and are qualified for use in extreme conditions. Thanks to their robustness and configurability, they are ideal for applications in marine, rail, industrial, and off-highway applications. See our online test event for more information.
