  • Hand-held power tool with jamming-detection sensor
    Patent number: 5401124
    Abstract: A hand-held machine tool has a housing, a tool rotatable about a rotational axis, a motor provided with a gear unit and driving the tool in rotation about the rotational axis, the gear unit having at least one rotating part which is arranged so as not to be axially parallel to the rotational axis of the tool, a bearing supporting the rotating part of the gear unit, and a sensor arranged at the bearing so that the sensor lies in an effective region of bearing forces which are produced by a moment of occurring gyroscopic effect when the housing rotates around the rotational axis of the tool.
