The traction motor of the wheel module - designed as a permanently magnetized synchronous machine - is a variant of the wheel hub motor developed by Schaeffler as early as 2013 in a research project. In the current design of the "Schaeffler Mover", each of the four electric motors delivers a continuous output of 13 kilowatts at 300 volts operating voltage and a temporary peak output of 25 kilowatts. The nominal torque of 250 Newton meters per motor can be doubled for a short time.
A specially developed vehicle dynamics control system enables each Intelligent Corner Module to be controlled individually and the functions of vehicle dynamics control (ESP), torque distribution between the driven wheels (torque vectoring) and all-wheel steering to be combined. Lateral movements can thus be implemented with virtually no lateral forces noticeable to the passengers. At the same time, this drive concept guarantees very high availability and reliability. The complete software for drive and steering control has been developed by Schaeffler, including a comprehensive safety concept.
A result of the high degree of integration, the drive and chassis require less installation space overall - the vacated area offers more space for passengers and storage space for goods in transit. The space created for the battery and auxiliary units allows compact vehicle dimensions. These can also be varied. Finally, the vehicle can also be converted to a longer and wider variant without having to make changes to the drive and chassis. The modular vehicle structure of the "Schaeffler Mover" creates the prerequisite for implementing numerous passenger and goods transport tasks with a largely uniform chassis. The body - which can be converted for the desired application - can be quickly separated from the platform, in which all the technology required for driving is bundled. Only some of the sensors required for autonomous driving are also integrated in the body.
