[0087] The position of the hole 811a corresponds to the position of the terminal 832. It may include rounded edges to accommodate the curved shape.

[0088] 18 and 19, a modification of the terminal 830 is shown in the form of three terminals U, V, and W. Terminals 830 are provided, and a total of 12 terminals 832 can be arranged.

[0089] FIG. 20 is a diagram illustrating a stator including an insulator, and FIG. 1 is a diagram illustrating a rotor.

[0090] Referring to FIGS. 20 and 21, a stator 300 of an actuator according to an embodiment includes: The stator cores may be implemented as an expanded stator in which adjacent stator cores are connected to each other. In the open-type stator, the stator core can be spread out on a plane in a strip shape. When the coil is inserted, the slot open is expanded, and the space factor of coil 1 is increased. Not only does this increase the winding efficiency, but it also allows the winding work on adjacent stator cores to be carried out at the same time. For example, it is possible to share the winding work of one coil 1 for two adjacent stator cores. Progressing to , you can reduce the fusing points by half.

[0091] At this time, the coil 1 wound around the stator 300 is positioned behind the insulator 310 (outside Specifically, the insulator 310 can be wound around the inner guide The inner guide 311 and the outer guide 312 may be , which serves to prevent the coil 1 wound around the insulator 310 from coming off. The side guide 312 includes an extension 312a extending upward. The extension 312a has a groove 3 The coil 1 wound around the stator 300 is inserted into the groove 312b. The coil 1 can be guided outside the insulator 310 .

[0092] FIG. 22 is a diagram illustrating the terminal and the sealing cover.

[0093] Referring to FIG. 22, the sealing cover 700 is a terminal power supply connected to an external power supply. The terminal body 831 may include a portion 600. The terminal body 831 may be elongated along the axial direction of the rotation shaft 100. The terminal power supply unit 600 is connected to the power supply unit 600 .

[0094] As described above, a motor router and an actuator including the same according to a preferred embodiment of the present invention are The data was examined in detail with reference to the attached drawings.
