  • Rotational direction indicator
    Patent number: 8777586
    Abstract: The inventive rotational direction indicator for an electric motor having a cooling fan has a baffle element movable between two positions and which can be arranged on an electric motor with a cooling fan in such a way that the baffle element is positioned in an airstream of the cooling fan whose direction depends on the rotational direction of the electric motor. The baffle element is respectively moved into one of its two positions by the electric motor as a function of the direction of the airstream. The rotational direction indicator has a display unit designed to visually indicate the position of the baffle element and can be arranged on an outer side of the electric motor. The rotational direction indicator has a display actuating unit which connects the display unit and baffle element to one another, and transmits the position of the baffle element to the display unit.
