摘要

The present invention relates to an electric motor structure with direct current (10) for applications in the automotive sector of the type for the adjustment of the seats, movement of window lifters and the like comprising:- A receiving housing (11) of sheet metal, which has a thickness (30) of 1,1 mm to 2,5 mm,- A tubular stator body (12) with four poles (26) has a thickness (27) of 1 mm to 2 mm comprising,- A rotor with twelve grooves (13), which has an external diameter (28) of 25 mm to 32 mm,- A drive shaft (14), which have a diameter (31) of 3,5 mm to 6 mm, wherein said collector (15) a diameter (32) of 10 mm to 13 mm,- A brush support cover (16) for closing of the housing (11),- Two sliding brushes (17, 18) which, with an angular distance (21) of 90° in a plane, which is orthogonal to the axis of rotation (x) is arranged with each other, with the length (22) of each brush (17, 18) corresponds to at least twice the working stroke, the width (23) of each brush (17, 18) 80% to 97% of the corresponding width of a lamella (25) of the collector (15) is,- The outer diameter (29) of the housing (11), of the 32 mm to 40 mm.n="16"
