Our Redundancy System.

IF A COMPONENT FAILS – THE SYSTEM CONTINUES TO RUN

The failure of one system component, such as the engine, is often synonymous with a failure or crash of the entire system.

This is exactly where the redundancy system from SOBEK comes in.

To reduce the probability of failure, we have developed a redundancy system based on a 2 x 3-phase BLDC motor and two powercontrollers. Under normal conditions, the two powercontrollers share the load. In an emergency, the entire system is designed in such a way that the elementary system function is maintained if a winding or a power controller fails.

In addition, we have redundantly stored safety-relevant algorithms for controlling the motor. Critical system states are detected and stored in time (predictive maintenance). Thanks to our redundancy system, we can recognize numerous events, intervene timely and significantly increase reliability. A decisive advantage over a non-redundant system.

Possible motor or controller malfunctions.

> Output stage of the powercontroller fails – redundant power controller jumps in

> Current measurement of the powercontroller fails – redundant powercontroller takes over

> Voltage measurement of the powercontroller fails – redundant powercontroller takes over

> Detection of a phase break in the motor – predictive shutdown of just one winding

> Communication error – full controllability possible, not just failsafe mode

> Motor phase short circuit – predictive shutdown of only one winding

Reliable systems certified according to EN 9100 .

In the aerospace industry, you place the highest demands on the components you supply. Your partner must be absolutely reliable and find the right solution for every problem. They expect the performance standards that many promise. But what gives you a secure feeling when ordering? Our EN 9100 certification certifies the high quality of our internal quality management in the aerospace sector. Hardly any other industry places such high demands on the safety and reliability of individual components. According to our certification, we fully meet these strict requirements in our business areas.
