[0038] This invention proposes a three-phase asynchronous motor frame structure for use in motor frame optimization processes.

[0039] Overall, the three-phase asynchronous motor frame structure proposed in this utility model mainly includes: a base housing 1, supporting connecting feet 5, a first heat sink assembly 2, a T-shaped base 3, and a suspension module 4; (See also...) Figure 1 It shows the arrangement of the base housing 1, the support connecting foot 5, the first heat sink group 2, the T-base 3 and the suspension module 4.

[0040] This utility model proposes a three-phase asynchronous motor frame structure with the following optimizations:

[0041] 1. The arrangement of the heat sinks has been optimized, increasing the heat dissipation area;

[0042] 2. The position of the terminal block 34 inside the T-type seat 3 has been optimized. The terminal block 34 is now set in the center. The old frame T-type seat was designed to be close to the load side, which may affect the use of the customer's installation surface when wiring, and the space was limited. The new frame T-type seat is moved to the center, which is more convenient. The height of the second heat sink group 35 has also been reduced to prevent the customer from bumping into the heat sink when installing wiring. A boss block 31 structure has been added to expand the wiring space inside the T-type seat 3 and facilitate on-site wiring operations.

[0043] 3. Making the lifting ring and frame into one piece makes lifting operations more convenient and increases lifting safety;

[0044] 4. The structure of the supporting connecting foot 5 is optimized to improve structural stability. The bottom support surface of the base housing 1 is changed from two strips to four points to improve structural stability and reduce the weight of the motor frame.

[0045] The aforementioned base housing 1 is cylindrical. Connecting blocks 11 are provided around the front and rear ends of the base housing 1. Support connecting feet 5 are provided at the bottom of the base housing 1. There are 4 support connecting feet 5, which are respectively provided around the bottom of the base housing 1. The support connecting feet 5 are located between the first heat sink group 2 on the left and right sides of the base housing 1 and the first heat sink group 2 at the bottom. The first heat sink group 2 is provided at the center of the left and right sides and the center of the bottom of the outer wall of the base housing 1. The first heat sink group 2 consists of several first heat sinks arranged in a row.

[0046] The aforementioned T-shaped base 3 is located at the center of the top of the base housing 1. The T-shaped base 3 includes: a boss block 31, a lead wire interface and cable passage 33, a terminal block 34, and a second heat sink assembly 35. The boss block 31 is located on the outer side wall at the center of the top of the base housing 1. The bottom of the boss block 31 is a wiring groove 32. The lead wire interface and cable passage 33 are spaced apart. The lead wire interface and cable passage 33 are located on the inner side wall at the center of the top of the base housing 1. The inner diameter of the lead wire interface and cable passage 33 is smaller than the inner diameter of the wiring groove 32. The top of the lead wire interface and cable passage 33 communicates with the wiring groove 32. The terminal block 34 is located at the center of the top of the base housing 1. The second heat sink assembly 35 is located on the front and rear sides of the terminal block 34 at the top of the boss block 31. The second heat sink assembly 35 consists of several second heat sinks arranged in a row. The third heat sink 12 is located on the left and right sides of the boss block 31 at the top of the base housing 1.

[0047] The aforementioned suspension module 4 is located on the top of the base housing 1 on the left and right sides of the outer side wall. The suspension module 4 is located between the T-base 3 and the first heat sink group 2. The suspension module 4 includes: an integrated hanging ring 41 and a fourth heat sink 42. The integrated hanging ring 41 is located on the top of the base housing 1 between the first heat sink group 2 and the third heat sink 12. There are two integrated hanging rings 41. One integrated hanging ring 41 is located on the front left side of the top of the base housing 1, and the other integrated hanging ring 41 is located on the rear right side of the top of the base housing 1. The fourth heat sink 42 is located on the left and right sides of the integrated hanging ring 41.

[0048] like Figure 4 The table shows the results of the frame stiffness analysis. The maximum stress and other parameters of the frame structure after the new design optimization all meet the design goal of ensuring the structural strength characteristics.

[0049] like Figure 5 The analysis charts show that the temperature of the optimized frame is slightly lower than that of the original frame.

[0050] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
