Patent ID: 7699687

Claim:
A hand-held sanding machine, comprising: an outer housing ( 1 ); a tool shaft ( 2 ) having an eccentrically positioned tool holder; and a brushless electric drive motor having a stator ( 6 ) positioned in the outer housing ( 1 ), having a rotor ( 7 ) fastened to the tool shaft ( 2 ), and lacking a shaft of its own and further including a control unit ( 15 ), where the mains voltage is rectified and the following capacitor (C 2 ) is so small that the voltage follows the rectified mains voltage and thus current is consumed from the network during the time when the voltage is loaded, characterized in that the motor is dimensioned in such a way that the nominal voltage of the motor is so much lower than the top value of the rectified mains voltage in relation to the required power that sufficient power correction is obtained when current is consumed during that part of the cycle when the voltage is higher than the nominal voltage of the motor and no current is consumed when the voltage is lower than the nominal voltage of the motor.
