Solutions for the drives of the future

How Blue Competence makes mobility more sustainable

Whether extremely economical combustion, hybrid or electric drives – there is no avoiding new drive concepts. By developing innovative technologies, the mechanical engineering industry can help to turn revolutionary prototypes into affordable mass-produced products.

Both the exploitation of all the potential to optimise the conventional drive train and new components for electrification of the drive train are fields in which the mechanical engineering industry cannot only demonstrate its technical know-how and experience but also has a series of solutions to offer.

Three specific insights

Optimisation and further development of hard magnetic materials

High-performance rare earth magnetic materials are a vital key to highly efficient electrification of the drive train (hybrid and direct drive). With the aid of considerably improved hard magnetic materials (i.e. permanent magnets), it is possible to increase the performance capacity of electric motors while also optimising the manufacturing and/or raw material costs. A research project is being carried out with the intention of highlighting possible ways that expensive additives (e.g. Dy) can be dropped.

Low speed concept for hydromotors

This concept reduces the rotational speeds of large-volume hydromotors and the number of components in the drive train so that the rotational speed of the diesel engine is converted into wheel revolutions directly as far as possible. The result of this is that the maximum speed of the vehicle is increased while the fuel consumption is reduced considerably.

Hybrid drives on the railways

In future, railway engines will be able to be operated with a hybrid drive system comprising a diesel engine and an electric motor. When starting up and accelerating, the battery delivers power to an electric motor. This technology is particularly efficient and economical on local stretches of track where frequent braking and acceleration is required: fuel consumption and carbon dioxide emissions can be reduced by up to 25%.
