[0065] According to the first embodiment of the present invention, the first flux ring 23 coupled with the ring magnet 22 inside is coupled to the first flux ring coupling portion 21 formed inside the motor case 20, and the armature 30 is inserted into the ring Magnet 22 in. On the other hand, the ring magnet 22 has a hollow cylindrical structure. Since a conventional yoke housing is not required, the seat motor according to the first embodiment of the present invention is miniaturized and lightened while being easy to assemble.

[0066] image 3 A structure is shown in which the first flux loop 23 is coupled to the motor housing 20 . image 3 for along figure 2 Schematic cross-sectional view taken along the direction AA' shown. As shown, the first flux ring 23 with the ring magnet 22 coupled inside is coupled to the inside of the motor housing 20, and the armature 30 is inserted inside the ring magnet 22 so that the armature 30 is rotatably coupled to the motor shaft 50...

Abstract

According to the present invention, a motor for a vehicle seat comprises: a motor housing, in the front portion of which a first flux ring joint portion is formed; a first flux ring which is coupled to the first flux ring joint portion, and which has a ring magnet attached to the inside thereof; a motor shaft located at the center of the first flux ring joint portion, and coupled to the motor housing such that the motor shaft is rotatable; and a rotor which is located at the center of the inside of the ring magnet, and which rotates together with the motor shaft.

Description

technical field [0001] The present invention relates to electric motors, and more particularly, to an electric motor for use in automotive electrical components, such as car seats, while having a novel magnetic field structure. Background technique [0002] In general, the backrest of a car seat is adjusted or changed in position by electrical operation of an electric motor, and such a car seat is called an electric seat or a power seat. Also, electric motors used in car seats are called seat motors. [0003] The structures of conventional seat motors have been disclosed in Korean Patent No. 10-0851884 and Japanese Patent No. 4275039. figure 1 An exploded perspective view of one of the conventional seat motors. [0004] refer to figure 1 , the traditional seat motor mainly includes a yoke (yoke) 100 , a motor housing 200 , an armature 300 , and a gear 400 . The yoke 100 has a steel yoke case 101 with a magnet 104 attached to its inner side and a shaft coupling portion 10...
