Abstract
A hand-held power tool includes a housing, a tool holder for holding an insert tool, an electrically commutated drive motor that is arranged in the housing and has a drive shaft mounted by at least one bearing, a fan impeller, and a sensor board for sensor-controlled commutation of the electrically commutated drive motor, the sensor board being arranged in the housing between the drive motor and the fan impeller. The power tool further includes at least one mounting element designed to arrange the sensor board in the housing in a manner mechanically decoupled from the electrically commutated drive motor. The sensor board and the fan impeller are arranged at an end of the electrically commutated drive motor facing away from the tool holder.
