Abstract: The present invention introduces an electrically driven snowmobile, i.e. an electric sled. The electric motor is applied along the primary driving axis so that its rotational force is applied directly or indirectly to the primary driving axis. The electric motor may locate either inside or outside the frame structure of the snowmobile, and either on the left-hand side or the right-hand side of the primary driving axis. One option of manufacturing the electrically driven snowmobile is to convert a traditional combustion engine driven snowmobile into an electrical one by removing some parts and adding the electric motor within the snowmobile. Another option of manufacturing the electrically driven snowmobile is to build a transmission chain from scratch, and by adding an electric motor along the primary driving axis.
