DRIVEN BY KNOWLEDGE!
We support the entire e-drive industry towards a new era of mobility by developing new technologies, methods and solutions to meet your requirements. Starting with the solution definition we offer a wide set of development services to our customers: from the idea to the first prototypes.
We are part of the CONNACTIVE developer network - an ecosystem of experts from a wide range of fields and disciplines. We work together under the motto "Cooperation speeds up Innovation" and jointly develop a new generation of electronic drive systems.
GOALS & REQUIREMENTS
The goals that developers are pursuing in the downsizing of electrical units can be summarized in six key points:
1. sustainable production: low material use and conservation of resources.
2. low costs: low costs for manufacturers and for the end customer.
3. more efficiency: constant or improved performance with lower consumption.
4. more compact shape: Less installation space and weight.
5. mechanical requirements: What can be implemented with which materials and processes?
6. electronic & software requirements: Which software and electronic solutions are available?
The adjacent graphic shows, based on the current status quo, where our goals lie - and how far we have already progressed with our CONNACTIVE eDrive.
BEST RESULT: HIGH INTEGRATION
CHALLENGE:
-
Stringent design and quality requirements for windings
-
Selection of types of windings according to the specific application
-
Placement of the power electronics in the motor
PRACTICE:
-
The PCBs are mounted directly on the busbars
-
Shorter transmission paths
-
More installation space
-
Prevents transmission losses through direct connection
RESULT:
We succeeded in creating shorter connections by intelligently integrating the power electronics directly in the motor, thus avoiding losses and achieving significant cost savings.
COOPERATION SPEEDS UP INNOVATION
CONNACTIVE
BEST METHOD: SIMULATION
CHALLENGE:
- Sustainable support for decision-making processes
- Alternative to prototype production and physical tests
- Keep future product and operating costs effective
PRACTICE:
- Simulation methods to calculate and analyse the physical behaviour of e-motors
- Two-stage simulation process for the electromagnetic design and simulation of the electric machines and their enironment
- Look at the product under the tolerances that occur in real life
- Optimize the product with simulations in the nominal state at different operating points
RESULT:
Digital twin simulations are the efficiency booster for the ongoing development of future-oriented e-drive solutions.

DEVELOPING AT HIGH SPEED!
Seven well-known companies from a wide variety of areas came together in autumn 2019 to maximize their joint innovation potential and accelerate development work through intensive exchange and close partnership.
Within an extremely short period of time, we thus achieved something which other specialists take years to do: we developed a new generation of electric drive systems, from blueprint close to B sample standard prototype - in only six months. Therefore our mission statement: Cooperation speeds up Innovation.
