OUR FOCUS AREAS

To create intelligent solutions making motors substantially smaller and more compact, with a noticeably higher power density and hence significantly enhanced efficiency we focus on alternative transmission solutions, better energy conversion and improved high torque auxiliaries.

HIGH FREQUENCY MOTORS

The advance of high speed drive systems increasingly leads to the need of new holistic eDrive concepts, so that such applications can be suitably designed in order to present actual advantages in terms of energy, efficiency and costs.

RX ROTOR

There’s no doubt about it: modern eDrives will be among the drive systems of the future. Which is why manufacturers and developers are absolutely committed to further optimizing electric drive units, tweaking everything from torque and power density to efficiency, weight and above all: production costs.

RX MOTOR

Downsizing" plays an increasingly important role in the development of electric motors.
Smaller, compact units with consistently high performance are the future of e-mobility, because smaller size automatically means sustainable material use: significantly less rare earths and other raw materials are needed, thus conserving resources.

POWER ELECTRONICS

Power electronics have a substantial influence on the development of electric vehicles. Because the efficiency of the “drive” system as a whole is largely dictated by the electronics and control systems. The electronics are traditionally split into power electronics and controllers.

Especially in the case of high-frequency 48 V motors where, for design reasons, the inductance of the motor is very low, it is crucial to locate the power electronics as close to the motor as possible - i. e. at the windings.

WINDING INTELLIGENCE

In order to improve efficiency in the overall system of high-frequency motors, we’ve created a simulation model to specifically address winding losses. Winding losses generally have significant impact on the efficiency of the motor, particularly in high-frequency systems. Winding losses can be categorized into a direct current component (DC) and an alternating current component (AC).

In order to design reliable systems with high efficiency, the accurate prediction of winding losses is more important than ever - from a sustainability perspective as well.

POWERSPLIT RX II

In 2019 we developed our innovative CONNACTIVE eDrive, which has already set new standards in electric mobility.

Now we’re taking our development work one step further: with a revolutionary planetary gearset that assumes the function of a power split device and perfectly connects the CONNACTIVE eDrive, conventional combustion engines and the all-new RX II.

HIGH TORQUE AUXILIARIES

AX MOTOR

Minimal weight for size: axial flux motors offer advantages when used in the drives of electric vehicles. Because they provide high torque at low rpm and require only minimal installation space. That’s why CONNACTIVE combines them with a classic RX unit – for optimum performance in situations where the eDrive needs to work harder.

Where the additional propulsion isn’t required, the AX motor can assume other functions. And: by combining two drive units, a redundant system is created which can provide emergency back-up operation in case of technical problems, for example.
