Adjustment of operational performance of an electric machine (e.g., using a computerized tool) is enabled. For example, a non-transitory computer-readable medium can comprise executable instructions that, when executed by a processor, facilitate performance of operations, comprising: deactivating a first sub-set of winding sectors, wherein the first sub-set of the winding sectors comprises at least one winding sector, and triggering an AC drive signal for a second sub-set of the winding sectors such that a rotor is rotated using the winding sectors of the second sub-set, wherein an electric machine comprises a stator and the rotor, wherein the stator comprises a set of N phase windings, wherein each N phase winding, of the set of N phase windings, forms p poles around a circumference of the stator, and wherein each p pole, of the p poles, is formed by the at least one winding sector.

The present disclosure relates to a cable system for cable condition monitoring, a use of such a cable system, a method for manufacturing such a cable system, a method for operating such a cable system and a computer program element for operating such a cable system. The cable system includes a first adapter unit, a first sleeve unit and a cable including at least a first end portion. The first adapter unit is connectable to an energy storage system and the cable is configured for transferring electric power to the first adapter unit. The first sleeve unit is arranged between the first adapter unit and the first end portion of the cable and configured for providing protection therebetween. The first sleeve unit includes a first sensor unit configured for generating data based on strain exerted on the first sleeve unit. The first sensor unit includes a first flexible electronic element extending at least partially to the first end portion of the cable.

A cleaning system for removal of contaminants from a surface of a vehicle component exposed to a gas or fluid flow, the cleaning system comprising: an excitation device adapted to be attached to the vehicle component in the vicinity of the surface exposed to contaminants, wherein the excitation device is configured to cause the surface to mechanically vibrate by transferring a vibrational excitation to the surface; wherein the frequency of the vibrational excitation is controllable to be based on the configuration of the vehicle component as well as other modelled/measured parameters.

Cleaning system for a vehicle component

An arrangement adapted for removing soot from an exhaust gas sensor in an exhaust gas system of a vehicle comprising a combustion engine, where the arrangement comprises a fluid outlet arranged in an exhaust gas conduit, and where the fluid outlet is adapted to impinge a blast of fluid on the exhaust gas sensor. The advantage of the invention is that an exhaust gas sensor can easily be cleaned in order to ensure a correct reading from the sensor.
