Therefore, the upper casing member 11 further has an upper cover 13 which is located at the bottom of the upper casing member 11; the lower casing member 21 further has a lower cover 23 which is located at the top of the lower casing member 21. The material of the upper and lower casing members 11 and 21 is plastic, and the materials of the upper and lower covers 13 and 23 are made of metal. The motor component 41 further has an upper fixing plate 44 and a lower fixing plate 45. The upper fixing plate 44 and the lower fixing plate 45 are respectively disposed on upper and lower sides of the stators 43 and 42 and are driven by the driving shaft 46. The upper cover 13 and the lower cover 23 are respectively provided with an annular latch 53 toward the upper fixing plate 44 and the lower fixing plate 45; the upper fixing plate 44 and the lower fixing plate 45 respectively respectively the upper cover 13 and the upper cover 13 The lower cover 23 protrudes from a ring wall 51; the upper and lower fixing plates 44, 45 are connected to the annular latch 53 by the annular wall 51; wherein each of the annular latches The caliber formed by 53 is larger than the diameter of each of the ring walls 51, thereby providing the upper and lower covers 13, 23 to closely fit the upper and lower fixing plates 45. The upper fixing plate 44 can be coupled to the upper cover 13 and form an upper sub-space R1. The lower fixing plate 45 can be coupled to the lower cover 23 and form a sub-space R2. One end of the driving shaft 46 passes through the lower sub-space R2. The drain vanes 33 in the drain box 31 are connected, and the other end of the drive shaft 46 is located in the upper subspace R1; the two bearings 48 are located in the upper subspace R1 and the lower subspace R2, respectively. Each of the oil-impregnated sponges 49 is filled in the upper subspace R1 and the lower subspace R2, respectively, and is in contact with each of the bearings 48. Wherein, the upper cover 13 and the lower cover 23 of the motor component 41 jointly form a complete motor.

The structure of the first preferred embodiment of the present invention has been described above, and the assembled state of the first embodiment of the present invention will be described next.

The motor module 10 of the first preferred embodiment of the present invention is assembled with the upper casing member 11 and the top of the motor member 41. At this time, the annular latch 53 of the upper cover 13 is fixed to the upper portion. The ring wall 51 of the plate 44 is tightly fitted to achieve the fixing; then, the lower case member 21 is combined with the bottom of the motor member 41, which is the ring of the ring cover 53 and the lower fixing plate 45 of the lower cover 23. The wall 51 is tightly fitted to achieve the fixing; finally, the drain box 31 is assembled under the lower casing member 21 to complete the assembly of the present invention. Thereby, the upper cover 13 and the lower cover 23 are combined with the motor component 41 to form a complete motor.

Accordingly, the present invention can be disposed on the bottom of the upper casing member 11 by the upper cover 13, and the lower cover 23 is disposed on the top of the lower casing member 21, and is further fixed to the fixing plate 44 and the lower fixing portion of the motor member 41. The combination of the plates 45 simplifies the assembly process, and the assembly speed is effectively improved, which is convenient.

In addition, compared with the prior art, the present invention can be effectively reduced in the prior art by the technical feature of the upper cover 13 being disposed at the bottom of the upper casing member 11 and the lower cover 23 being disposed at the top of the lower casing member 21. The distance between the metal casing and the plastic casing further reduces the volume of the motor.

However, in addition, the diameter of each of the annular latches 53 may be set to be smaller than the diameter of each of the annular walls 51, thereby providing the upper and lower covers 13, 23 to closely fit the upper and lower fixing plates 44, 45; It can be seen that the same effect can be achieved by different assembly forms.

Next, referring to FIG. 6 and FIG. 4, a motor module 10' according to a second preferred embodiment of the present invention has substantially the same structure as that of the first preferred embodiment, and the difference is that :

Referring to Fig. 6, in the second preferred embodiment, the two bearings 48' are exemplified by ball bearings. The upper cover 13 and the lower cover 23 are not provided in the second preferred embodiment because the upper cover 13 and the lower cover 23 are not required when the ball bearing is used. Therefore, in the assembly, the arrangement of the upper cover 13, the lower cover 23, the upper fixing plate 44, and the lower fixing plate 45 can be omitted (please refer to FIG. 4); The motor module 10' of the preferred embodiment can be combined with different types of bearings, and can also simplify the assembly process and reduce the volume of the motor, and is convenient for both industry and use.

The remaining structure of the second preferred embodiment and the achievable functions are the same as those of the first preferred embodiment, and the applicant will not repeat them.
