Stator foar aspiration motor, aspiration motor and in-car sensor using the same

A stator for an aspiration motor, the stator comprising:

• a stator support plate in which a bearing seat in which a number of terminal insertion holes are formed in first and second areas, respectively, and whose position is set up at the lower portion of the central portion thereof, a back yoke which is located on the outer circumference of the bearing seat and a hall element are inserted at predetermined positions according to a magnetic circuit formed by the back yoke;
• a support boss which is vertically extended from the central portion of the stator support plate;
• a bobbin which is bent and formed on the lateral surface of the support boss, and which is integrated with the stator support plate, to thereby provide a space in which a wire is wound;
• a stator coil which is formed by making a wire wound in the space provided by the bobbin;
• and
• a control printed circuit board (PCB) which is combined with the bottom surface of the stator support plate and supplies a drive signal to the stator coil.

An in-car sensor comprising:

• a rotor in which an impeller and a shaft are integrally formed with a magnet, and which inhales and exhales car indoor air according to rotation of the magnet and the impeller;
• a stator which comprises a stator coil whose shaft is rotatably combined with the central portion of the support boss which is vertically extended from the central portion of the stator support plate opposing the rotor, and which is wound around a bobbin which is bent and extended on the lateral surface of the support boss;
• a control printed circuit board (PCB) which is combined with the bottom surface of the stator support plate and supplies a drive signal for the stator coil;
• a housing which is fixedly combined with a car while forming an external appearance, and which has an air-stream path from an inlet of the leading end of the housing to an outlet formed at the lateral surface thereof, the housing having upper and lower housings which fix the control PCB therebetween;
• a temperature sensor which is positioned in the air-stream path through which air is inhaled by the rotor;
• and
• a signal PCB which transfers a signal detected by the temperature sensor to a controller of the car.
