Patent number: 8487503Abstract: A hand power tool with an oblong motor housing, particularly used as a handle, houses an electric collector motor. The brushes of the motor are housed in a brush holder with a brush shaft in a spring loaded way. Furthermore, the brush holder is solely/individually fixed in the motor housing, to which an axis intersection is associated, particularly a longitudinal, a vertical, and a transversal axis. According to the invention, the hand power tool is arranged in the motor housing in a space-saving manner with the shaft of the brush holder arranged opposite the vertical axis of the motor housing at an angle of approximately 20° in a laterally displaced way, particularly radially, relative to the longitudinal axis.Type: GrantFiled: July 7, 2009Date of Patent: July 16, 2013Assignee: Robert Bosch GmbHInventors: Florian Esenwein, Manfred Lutz, Thomas Schomisch
