9 is a perspective view showing the configuration of a varnish liquid application device of a motor stator according to a fourth embodiment of the present invention.

Referring to FIG. 9 , it can be seen that a plurality of varnish liquid application devices 100 of the motor stator are disposed on the arrangement unit 110 .

That is, the user arranges the rotating unit 120 and the inclination adjusting unit 130 at both ends of the disposing unit 110 to face opposite directions, respectively. In addition, when the stators 1, which are the varnish liquid application targets, are respectively disposed on the connecting chuck 128, the application operation can be simultaneously performed on a plurality of stators.

Here, the configuration of the rotating unit 120 and the inclination adjusting unit 130 is the same as that of the previous embodiment, so a detailed description thereof will be omitted.

In addition, the inclinations of the rotating units 120 at both ends of the arrangement unit 110 may be set to be the same, but may be set differently according to the user's needs.

In addition, in FIG. 9 , the varnish liquid application device 100 of the motor stator shown in FIG. 2 is disposed on the upper portion of the arrangement 110 , but the motor stator shown in FIG. 5 or FIG. 8 according to the user's needs of the varnish liquid application device 100A, 100B may be disposed.

In the present invention configured as described above, when the varnish liquid is supplied to one end of the stator in a state in which the stator of the motor is inclined at a predetermined inclination, the varnish liquid flows from one end of the stator to the other end and can be uniformly applied to the stator. In addition, the present invention does not use components such as chains or sprockets in the process of transmitting the driving force of the driving motor to rotate the stator, so that vibration does not occur in the driving force transmission process. In addition, in the present invention, when an abnormality occurs in the rotating part that rotates the stator, the arranging part in which the rotating part is disposed is separated from the disposed position, and the varnish liquid application operation is continuously performed by disposing the disposed part in which the normal rotating part is disposed in the separated position. can be
