15+ Years of Industry Expertise: WiredWhite at a Glance
Our Background
Our team, composed of PhD holders with extensive academic backgrounds, is internationally recognized for advancing the fields of electric machine design, system modeling, software development, and testing. With multiple IEEE publications, we have presented our work at prestigious conferences worldwide, including ITEC, ICEMS, ECCE Asia, SPEEDAM, EVS KINTEX, and many others.
We actively contribute to global electrification projects, collaborating closely with multidisciplinary teams across Europe, America, and Asia, driving innovation and fostering international cooperation in the electrification domain.

Aerospace
We bring extensive experience working with a major global aerospace company at its advanced aviation site in Garching, specializing in hybrid-electric applications. Our work adhered to the environmental conditions and test procedures for airborne equipment, ensuring compliance with industry requirements for the environmental testing of avionics hardware.
We have contributed to the development of propulsion systems in several German and European hybrid-electric aviation programs, supporting the transition from aircraft with conventional gas turbines to hybrid-electric propulsion systems powered by fuel cells and stabilized by high-voltage (HV) batteries. As component and product owners for electrical drives within the project team, we played a key role in developing flight-altitude-ready, flight-worthy electric machines, power converters, and drive control software.
Additionally, we were involved in aviation projects focused on fully electrically driven aircraft, contributing to system engineering and requirements engineering for battery packs and their sub-components, such as solid-state power controllers and battery power distribution cards. Our efforts supported one of the leading eVTOL unicorn startups based in Oberpfaffenhofen, helping it achieve significant milestones toward a successful piloted flight campaign.

Automotive
Our team contributed to major projects for the two largest German car brands and OEMs, focusing on platform technologies for battery electric vehicles. This included developing application software functions for eDrive systems and designing permanent magnet synchronous machines (PMSM) with both internal and surface-mounted rotor structures.
The final product, developed in compliance with ISO 26262, adhered to ASPICE (Automotive Software Process Improvement and Capability Determination) and ASIL (Automotive Safety Integrity Level) standards. It has been successfully brought to market, meeting the highest industry requirements for safety and reliability.

Electric machine
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.

Software
We contributed to model-based software development for drive control algorithms, including field-oriented control (FOC) for IPM machines. Our work involved modeling electric machine losses—copper losses (DC and AC), stator and rotor iron losses, friction losses, and magnet losses—and enhancing torque accuracy in torque control algorithms.
Additionally, we developed eDrive derating functions such as stator and rotor thermal derating based on temperature signals or estimations, I²t derating, voltage derating, and more. These functions were designed to prevent system shutdowns, eDrive component failures, or the loss of the entire traction drive system.
Moreover, we performed thermal modeling of the electric machine and power converter, leveraging loss calculations and energy equations to ensure system reliability and performance.

Systems & Project Management
Our team has good expertise in the development of EV chargers and charging station solutions. We have worked on simulation models that describe energy flow between the charger and the vehicle’s power network, enabling optimized energy management and performance. Additionally, we have contributed to creating interface control documents (ICDs) for the charging system and the overall power system of the EV, ensuring smooth integration and reliable operation across all components.
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.”

Simulink Model for the Analysis and Development of Hybrid Electric Vehicle Power Networks
#UseCase #SoftwareDevelopment
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.

Electric Machine Design of a Claw-Pole Alternator
#UseCase #HardwareDevelopment
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.
