Abstract

Disclosed are a built-in motor for use in a dishwasher or the like. The built-in motor is penetrated and installed in the bracket, the center portion of the bracket, and the load side is supported on the bracket adjacent to the shaft protruding outward of the bracket, the rotor pressed into the shaft, facing the rotor In a built-in motor having a stator and a pair of bearings installed on the shaft, the bracket surrounds the side surfaces of the rotor and the stator toward the load side with respect to the center of the rotor and the stator, and the bracket and the stator Fastened to each other, the rotor is press-fitted to the half-loaded end side of the shaft, and the bearing is installed at the portion of the shaft between the bracket and the rotor. The built-in motor is reduced in volume and weight by removing the portion of the half load side bracket. In addition, since the bearing is provided between the bracket and the stator, the volume is further reduced compared to the conventional motor in which the bearings are installed on both sides of the stator.

Description

Built-in Motor {EMBEDED MOTOR}

The present invention relates to a built-in motor used in a dishwasher or the like.

1 is a view showing the configuration of a conventional built-in motor, it will be described.

As shown, the bracket 11 is provided. The bracket 11 has the first and second brackets 11a and 11b coupled to each other by the screw 13, and the shaft 15 penetrates and is installed in the center of the bracket 11. At this time, the end of the load side shaft 15 is installed to protrude outward of the bracket 11, and the end of the half load side shaft 15 is supported inside the bracket 11. Then, the shaft 15 is a rotor The 17 is press-fitted and provided, and the stator 19 is attached to the bracket 11 so as to face the rotor 17 so as to face each other. In addition, bearings 21 and 23 for supporting the shaft 15 are provided at portions of both side shafts 15 of the rotor 17 and between the half-load bearing 23 and the second bracket 11b. A spring 25 is provided to prevent the 15 from being pushed to the half load side. Thus, when power is applied to the motor, the shaft 15 is rotated while the rotor 17 is rotated by the electric and magnetic action of the rotor 17 and the stator 19.

However, the conventional built-in motor as described above has the disadvantage that the structure is bulky and heavy weight.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a built-in motor that can be compact and lightweight.

The built-in motor according to the present invention for achieving the above object is a bracket, a shaft penetrating and installed in the central portion of the bracket, the load side protrudes out of the bracket, the rotor is pressed into the shaft, the rotor In the built-in motor having a stator supported on the bracket adjacent to and adjacent to the and a pair of bearings installed on the shaft,

The bracket surrounds the side surfaces of the rotor and the stator toward the load side with respect to the center of the rotor and the stator, the bracket and the stator are fastened to each other, and the rotor is press-fitted to the half load side end side of the shaft, The bearing is installed at the portion of the shaft between the bracket and the rotor.

Hereinafter, a built-in motor according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

2 is a view showing the configuration of a built-in motor according to an embodiment of the present invention.

As shown, a bracket 51 having one side cut out is provided, and a shaft 53 penetrates and is installed at the center of the bracket 51. At this time, the end of the shaft 53 on the load side projects outward of the bracket 51, and the rotor 55 is press-fitted to the end side of the shaft 53 on the half load side.

The stator 59 is coupled to the bracket 51 by a screw 57. The stator 59 is coupled to the bracket 51 so as to face the rotor 55 while being adjacent to the stator 59. A pair of bearings 61a and 61b having a predetermined distance therebetween are provided at a portion of the shaft 53 between the bracket 51 and the rotor 55. The bearing 61 is supported by the bracket 51 to support the shaft 53 to rotate smoothly. In addition, a rubber washer 63 is inserted into a portion of the shaft 53 between the bearing 55b adjacent to the rotor 55 and the rotor 55 of the pair of bearings 61, thereby bearing 61b. It is prevented from being pushed toward the rotor 55 side.

The bracket 51 of the built-in motor according to the present embodiment is provided in a form in which one side is cut and surrounds the shaft 53, the rotor 55, and the stator 59 on the load side. Therefore, the volume and weight of the entire motor are reduced. Moreover, since the bearing 61 is provided in the shaft 53 between the bracket 51 and the stator 55, the volume is further reduced.

As described above, the built-in motor according to the present invention is reduced in volume and weight by removing the portion of the half load side bracket.

In addition, since the bearing is provided between the bracket and the stator, the volume is further reduced compared to the conventional motor in which the bearings are installed on both sides of the stator.

In the above, the present invention has been described in accordance with one embodiment of the present invention, but those skilled in the art to which the present invention pertains have been changed and modified without departing from the spirit of the present invention. Of course.
