Abstract
An electrical tool includes a housing having inlet (7) and outlet (8) openings, a brushless electric motor (2) and an inverted rectifier (3) both arranged in the housing (9) between inlet (7) and outlet (8) openings in an air stream (5) of an air volume (6), and a link condensator (10) located in the housing (9) in the air stream (5), with the inverted rectifier (3) being arranged, in the air flow direction, downstream of the link condensator (10) and upstream of the electric motor (2).
