Empowering Your Success: Expert Engineering Services to Keep You Leading the Market
WiredWhite GmbH is a reliable full-cycle engineering services provider who specializes on helping companies in the e-mobility, renewables and other sustainable industries to drive their product development success with high quality standards, expertise and great value for money.
15+ Years of Industry Expertise: Our Background
Our team, composed of PhD holders with extensive academic backgrounds, is internationally recognized for advancing the field of electric machine modeling and testing. With multiple IEEE publications, we have presented at prestigious conferences worldwide, including contributions to ITEC, ICEMS, ECCE Asia, SPEEDAM, and EVS KINTEX.
We have extensive experience working with a major global aerospace company at its advanced aviation site in Garching, specializing in hybrid-electric applications and adhering to DO-160 and DO-178C best practices. This includes contributions to several German and European hybrid-electric propulsion programs. We supported the upgrade of aircraft, transitioning from conventional gas turbines to hybrid-electric propulsion systems with fuel cells. As part of the electric motor and drive components team, we contributed to this significant development. Furthermore, we have been involved in battery development, system engineering, and requirements engineering for a leading eVTOL startup based in Oberpfaffenhofen, supporting their efforts toward a successful piloted flight campaign.
We support automotive and eMobility projects with our expertise in developing electric machines and drives for hybrid-electric vehicle applications and 48V power networks. Our contributions include developing thermal models for eDrives using the MATLAB Simulink environment, performing software requirements engineering in Polarion, and conducting FEM analysis with Maxwell and Motor-CAD to optimize torque ripple in permanent magnet synchronous machines (PMSMs). Additionally, we bring experience from collaborating with the world’s largest motor developer on a project for a France-based global OEM.
Our team members co-developed model-based application software using MATLAB, TargetLink, and dSPACE for drive converters for Germany’s largest OEM. Working as part of an international SCRUM team, we followed the V-Model development approach to deliver high-quality results. Our work included developing software functions for eMotor derating (traction drive), electric machine loss modeling (PMSM), and supporting the Internal Permanent Magnet (IPM) motor control DRCO team. The final product, fully compliant with ISO 26262, ASPICE, and ASIL standards, has been successfully brought to market.
Whether it’s electric machine development, embedded software development, or system engineering, our team is ready to support you in tackling complex challenges and advancing your product to testing, prototyping, and detailed design freeze stages. We can begin our collaboration at the Request for Information (RFI) stage or seamlessly integrate into your current project phase, ensuring smooth progress while adhering to industry best practices in project management. Our expertise extends to guiding the final, safe product through certification and successfully bringing it “to the streets.”

Previous Cases
Simulink model for the analysis and development of hybrid and electric vehicle power networks.
Task
Create a model that contains the most significant components of a low voltage electrical network, such as alternator, rectifier, loads and battery, designed in form of sub-models. The power network model had to be designed in such a way that the single sub-models can be adjusted or completely replaced following the modular ideology.
Our work
Based on customer requirements the given excited multiphase synchronous machine model has been created and parametrized. Taking care of the tuning for the excitation current PI controller was taken over by the model-based Software Development team of WiredWhite as well. For the modelling of power electronics, multiple options such as Simscape, SimPowerSystems and Plecs has been considered and closely investigated.
In this model WiredWhite team has examined modelling of every single component such as the sub-model of the alternator and the sub-model of the excitation current control, as well as the functional principle of the vehicle power network while running simulations of automotive-typical test cases or driving cycle.
Finally, the model and the control loop have been verified by comparison of simulation results with the measurement results on a test bench.
Results
The typical use case of starting the engine (mimicked by a DC- electric machine) and impact of low voltage generator on vehicle power network and the voltage stability. Our team has modelled a detailed speed profile of the real drivetrain and captured the excitation and load currents and actual voltages, as well as the generator usage. With the laboratory experiments the team was able to verify the quality of the developed model.
Conclusion
This is just one example of a model-based software development project. Our team can provide you a tailor-made decision in the software development for automotive applications.
Hardware development project: electric machine design of a claw-pole alternator.
Task
Create an electric machine design of a claw-pole alternator with a delta-connected six-phase stator winding, rotor winding with the current control and two passive rectifiers.
Our work
The model had to be co-simulated with the model of the power electronics.
Relatively large nominal and maximum speed of the application makes the FEM simulation task more complicated and requires consideration and subsequent investigation of the proximity and skin effects in the stator winding of the machine.
The rotor design considers magnets between-claws, to compensate the leakage flux of the claws and for the enhancing of the main flux of the stator winding.
Results
Based on the created 3D FEM co-model, the behaviour of the automotive six-phase claw-pole alternator and power electronics in the vehicle power network has been investigated. In addition to the FEA, Matlab Simulink models of power electronics, electrical machine and other power network components have been parametrized to provide a detailed analysis of a vehicle power network.
Conclusion
With regards to e-machines, beside the electromagnetic design our team can also support you with insulation system design, mechanical strength analysis and calculation, thermal modelling and cooling system design.
