| 简介 |
The invention relates to an improved structure (10) of a direct current- transmission electric motor, in particular for window winders, seats, Wiper and the like, comprising an electric motor (11) having a receiving housing (12) for a stator body (13) and a corresponding rotor (14) with drive shaft (15), a housing (16), the carrying of reduction gears, an electronic board (17) for the power supply, measuring the position or engine controller, a connecting part (18), the forms a plug for supplying power to the electric motor or an electric measuring element (11). The specific nature of the invention is that the receiving housing (12) and the housing (16) a one-piece body (19) are made of plastic, wherein in the receiving housing (12) of the stator body (13), comprising a tubular magnet (20) the type of rare earths, surrounded by a metallic wall (31) for receiving the magnetic field, and the rotor (14) are mounted, whose drive shaft (15) at the free end (23) of the drive shaft (15) that is helping the screw portion (24) for transmitting torque is opposite, the corresponding collector (21) and a collection magnet ring (22) for sensor means (28) for the detection of position and speed, wherein said reception housing (12) by a cover (25) is closed, the supports forms the bottom receives (26) of the receiving housing (12) is mounted in the axial direction and in its interior the electronic card (17) or a shaped carrier (317), the brushes (27), sensor means (28) for the detection of position and speed of the rotor and connector (29) for the power supply and the signal transmission, wherein connecting pins (29a, 229a, 329a) selectively on the card (18) or the shaped body (317) are incorporated, the adapted to be inserted into the connecting part (18) of the cover (25) are provided, or in the connecting part (118) are integrated. |
