Description

Motor frame

The present invention relates to a frame, and more particularly to a motor frame.

The existing motor frame is designed to be assembled by welding as a whole. Its size is limited by the length of the motor core. If it is to accommodate motors of different lengths, it needs to be redesigned and manufactured. And if there is a problem with the frame quality or the design is wrong, it is not easy to correct the design. In serious cases, the entire motor frame must be scrapped, resulting in a waste of time, manpower, and money. Therefore, there is still room for improvement in the existing motor frame.

Therefore, the object of the present invention is to provide a motor frame that can solve at least one of the above problems.

Therefore, in some embodiments of the motor frame of the present invention, it is suitable for accommodating a motor, and the motor frame includes a first frame, including a first through hole suitable for accommodating the motor; a middle support unit, which is detachably connected to the first frame and extends away from the first frame, and the middle support unit is suitable for accommodating the motor; and a second frame, which is detachably connected to the middle support unit, and the second frame includes a second through hole suitable for accommodating the motor.

In some embodiments, the middle support unit includes a plurality of longitudinal support bars extending between the first frame and the second frame.

In some embodiments, the middle support unit further includes a plurality of transverse support bars arranged side by side and extending between the longitudinal support bars.

In some embodiments, the middle support unit further includes an upper cover plate connecting the first frame and the second frame and a lower cover plate connecting the first frame, the second frame and the upper cover plate, and the upper cover plate and the lower cover plate jointly cover the longitudinal support bars.

In some implementations, the first frame further includes a first frame body defining the first through hole and a plurality of first vents formed in the first frame body and connected to the first through hole.

In some implementations, the second frame further includes a second frame body defining the second through hole and a plurality of second air holes formed in the second frame body and connected to the second through hole.

In some implementations, the area of each second air hole is larger than the area of each first air hole, and the distance between each second air hole and the corresponding upper cover plate or lower cover plate is smaller than the distance between each first air hole and the corresponding upper cover plate or lower cover plate.

The present invention has at least the following effects: the motor frame can be divided into the first frame, the second frame and the middle support unit located between the first frame and the second frame, so that the error tolerance rate can be improved, and the first frame and the second frame can be pre-produced, and then the matching design of the middle support unit can be changed according to the length size difference caused by the volume length corresponding to the motor horsepower to be accommodated, which can effectively save manufacturing time and cost.

Before the present invention is described in detail, it should be noted that similar components are represented by the same reference numerals in the following description.

Referring to FIG. 1 and FIG. 2, an embodiment of the motor frame of the present invention is suitable for accommodating a motor (not shown). The motor frame includes a first frame 1, a middle support unit 2 and a second frame 3. The motor has a driving end, a non-driving end opposite to the driving end and an inner fan disposed at the driving end, and the first frame 1 is suitable for placing the non-driving end, and the second frame 3 is suitable for placing the driving end. The volume of the second frame 3 is larger than the volume of the first frame 1, so that there is enough space for the inner fan to be placed.

Referring to FIGS. 1 to 3 , the first frame 1 is a substantially square frame, which includes a first frame body 11, a first through hole 12, and eight first air holes 13. The first frame body 1 defines the first through hole 12, which is substantially circular and suitable for accommodating one end of the motor (not shown). The first air holes 13 are formed in the first frame body 11 and connected to the first through hole 12, and are arranged at equal angles around the first through hole 12. The number of the first air holes 13 is not limited to eight, and may be other numbers in other embodiments, as long as there are more than one.

The middle support unit 2 is detachably connected to the first frame 1 and extends away from the first frame 1, and is detachably connected to the second frame 3. The middle support unit 2 is suitable for accommodating the motor (not shown), and includes eight longitudinal support bars 21 extending between the first frame 1 and the second frame 3, sixteen transverse support bars 22 arranged side by side and extending between the longitudinal support bars 21, an upper cover plate 23 connecting the first frame 1 and the second frame 3, and a lower cover plate 24 connecting the first frame 1, the second frame 3 and the upper cover plate 23. The longitudinal support bars 21 and the transverse support bars 22 are used to support the motor (not shown) to improve the structural strength. Two transverse support bars 22 are arranged between every two longitudinal support bars 21. The upper cover plate 23 is fixedly connected to the first frame 1 and the second frame 3 in a locking manner. The lower cover plate 24 is also fixedly connected to the first frame 1, the second frame 3 and the upper cover plate 23 in a locking manner. The upper cover plate 23 and the lower cover plate 24 jointly cover the longitudinal support bars 21 and the transverse support bars 22 to achieve waterproof and windproof effects. The number of the longitudinal support bars 21 is not limited to eight, and in other embodiments, it can also be other numbers, as long as there are more. The number of the transverse supporting bars 22 is not limited to sixteen, and in other embodiments, the number may be other numbers, as long as there are more than one.

Referring to FIG. 1 , FIG. 2 and FIG. 4 , the second frame 3 is substantially a square frame, which includes a second frame body 31, a second through hole 32 and eight second air holes 33. The second frame body 3 defines the second through hole 32, which is substantially circular and suitable for accommodating the other end of the motor (not shown). The second air holes 33 are formed in the second frame body 31 and connected to the second through hole 32, and are arranged at equal angles around the second through hole 32. The area of each second air hole 33 is larger than the area of each first air hole 13, and the distance between each second air hole 33 and the corresponding upper cover plate 23 or lower cover plate 24 is smaller than the distance between each first air hole 13 and the corresponding upper cover plate 23 or lower cover plate 24. The number of the second air holes 33 is not limited to eight, and may be other numbers in other embodiments, as long as there are more than one.

Referring to FIG. 1 , FIG. 3 and FIG. 4 , by disposing the first air holes 13, the second air holes 33, the upper cover plate 23 and the lower cover plate 24, a plurality of air ducts surrounding the outer periphery of the motor (not shown) can be formed. The first air holes 13 are for ventilation. When the inner rotor of the motor rotates, the wind energy passes through the second air holes 33 along the above-mentioned air duct and is sucked by the inner fan (not shown) placed in the second frame 3, and then guided to an external heat dissipation device (not shown), achieving a heat dissipation cycle design, which can effectively improve the heat dissipation effect. In other embodiments, the first air holes 13 may be shielded by eight air hole covers (not shown) disposed on the first frame 11, ensuring that the wind energy emitted by the inner rotor of the motor when rotating passes through the second air holes 33 along the air duct as described above, and is sucked in by the inner fan (not shown) placed in the second frame 3.

In summary, the motor frame of the present invention can be divided into the first frame 1, the second frame 3 and the middle support unit 2 located between the first frame 1 and the second frame 3, so that the fault tolerance rate can be improved, and the first frame 1 and the second frame 3 can be pre-produced, and then according to the length size difference caused by the volume length corresponding to the horsepower of the motor to be accommodated, the matching design of the middle support unit 2 can be changed, which can effectively save the manufacturing time cost, so the purpose of this invention can be achieved.

However, the above is only an example of the implementation of the present invention, and it should not be used to limit the scope of the implementation of the present invention. All simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the patent specification are still within the scope of the patent of the present invention.
