About.
INSPIRED BY DIFFERENCE.
We come into place when applications require high-performance and modern thermal management, where redundancy systems are required for safety-critical areas or installation space, and saving weight is an essential aspect.
Thanks to our fundamental know-how for hydraulic and electronic components and systems, we develop integrated system solutions for various applications, such as electromobility in the air, the sea, and on land or mobile applications like hand-held tools as well as intelligent control of media for cooling systems of motors, batteries, inverters.
The technical demands like vast temperature differences, fluctuations in pressure, and high coolant flow are easy tasks for our pumps and valves. All our products come with an integrated intelligent controller (CAN, LIN, UART, PWM, etc.) including bi-directional communication protocols. Of course, software and hardware can be quickly adapted to customer-specific applications. Our components are developed and produced in-house and ensure performance and reliability.
Our Redundancy System.
IF ONE COMPONENT FAILS – THE SYSTEM CONTINUES
The failure of one system, such as the motor, must not be synonymous with a failure or crash of the entire system.
This is exactly where SOBEK’s redundancy system 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 control electronics. Under normal conditions, the two control electronics share the load. In an emergency, the overall system is designed to maintain total power in case of failure of one winding or one control electronics.
In addition, we have redundantly stored safety-relevant algorithms for controlling the motor. Critical system states are also detected and documented in good time (predictive maintenance). Our redundancy system allows us to identify numerous events that offer decisive advantages over a non-redundant system and do not immediately lead to a catastrophic failure.
Power amplifier fails – redundant ECU takes over
Current measurement fails – redundant ECU takes over
Voltage measurement fails – redundant ECU takes over
Motor phase break – Full performance
Communication failure – Full control, not just failsafe mode
INTELLIGENCE.
Our products come with an integrated Control Electronics Unit – reduced complexity, increased information.

Competences.
WE START WHERE OTHERS STOP.
Hydraulic pump design and production
High-power density pumps are our specialty. You give us your operating specifications and medium you plan running through the pump. Finally, we need to know what the nature of the space in which the pump will work is – and we deliver.
Electric motor design and production
The selection of the right motor can reduce energy and maintenance costs. because the application is running with the defined operating point. To do this, the balance between torque, speed and inertia must be right when designing the motor – for that we have good eye.
Electronic Control Unit design and production
The combination of the motor and ECU selection simplifies the process, largely eliminates the need for post-installation tests, increases reliability, and reduces maintenance. The result: A reliable, harmonious electric unit.
Optimization of power density
We are experts when it comes to getting the most out of a project. To do this we use our minds and make use of state-of-the-art software and hardware tools to optimize the power density of the solution.
Development, manufacturing and validation in-house
We have developed robust internal processes to handle the entire value chain, in-house. This drives effective communication through the various channels, makes us agile, improves cycle speed, increases efficiency. The result: improved customer experience.
State-of-the-art software tools and manufacturing techniques
We have the capacity to analyze the customer’s technical problems and challenges with the help of our interdisciplinary teams, using advanced technologies, and supporting software solutions.
