Description

Technical Field

[0001] The utility model relates to a motor base with better heat dissipation effect. Background Art

[0002] The motor is a mature existing device and a widely used and indispensable product. Motors are divided into asynchronous motors, explosion-proof motors, etc. according to different requirements. The principle and structure of motors are very mature, but there are also some small problems. For example, the heat dissipation effect of the motor can be further improved. The inner wall of the existing motor housing is smooth without other structures. When installing components such as the stator core, it depends on the experience of the installer. That is, the installation position of the stator cannot be standardized, and there will be deviations in the installation positions of each installer. Moreover, in order to prevent over-installation, the whole installation needs to be very careful, which will reduce work efficiency. Content of the Utility Model

[0003] The utility model mainly solves the technical problems existing in the prior art, and thus provides a motor base with better heat dissipation effect that is convenient for installation and has good heat dissipation effect.

[0004] The above technical problems of the utility model are mainly solved by the following technical solutions:

[0005] A motor base with better heat dissipation effect of the utility model includes a main housing. The inside of the main housing is a cavity. One end is used to set a fan, and the other end is used for external connection. Heat dissipation ribs are arranged on the inner side of the end for external connection. The heat dissipation ribs are spiral and have more than 2 turns. A reserved cavity for reserving the position of the hot compress element wiring box is arranged at the position of the heat dissipation ribs.

[0006] Preferably, the cavity inside the main housing is divided into a stator cavity and a part for the heat dissipation ribs.

[0007] Preferably, a retaining ring is arranged between the stator cavity and the heat dissipation ribs for limiting.

[0008] Preferably, a plurality of heat dissipation fins are evenly distributed on the outer peripheral surface of the main housing.

[0009] Preferably, a base is arranged below the main housing, and a wiring box is arranged above.

[0010] The beneficial effects of the utility model are:

[0011] By arranging a plurality of heat dissipation rings on the inner side of the end, the heat can be concentrated, and heat dissipation can be achieved faster according to the principle of heat transfer. The design of the retaining ring enables the stator to quickly find the limited position during installation and will not be installed in place inaccurately, greatly facilitating the installation of the stator. Description of the Drawings

[0012] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will briefly introduce the drawings required for use in the description of the embodiments or the prior art. Obviously, the drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings.

[0015] The following will elaborate on the preferred embodiments of the present invention in conjunction with the drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0016] As Figure 1-2 shown, a motor machine base with better heat dissipation effect is mainly used for the outer shell of the motor; it includes a main housing 1 with a cavity inside. One end is used to set a fan, and the other end is used for external connection; heat dissipation ribs 5 are arranged on the inner side of the end of the external connection; the heat dissipation ribs 5 are in a spiral shape and have more than 2 turns. When in use, due to the action of the fan at the other end, heat will be concentrated at one end of the heat dissipation ribs 5. The inner sides of the ends of the existing same-type casings are smooth, so the heat will be more dispersed. With the heat dissipation ribs 5, there are protruding ribs, which will form a step, and the heat will be more concentrated on the heat dissipation ribs 5. At this time, when the heat on the outer side of the end is lower, according to the principle of heat exchange, the heat inside will be transferred to the outside, so as to improve the heat dissipation effect inside. A reserved cavity 7 for reserving the position of the hot compress element junction box is arranged at the position of the heat dissipation ribs 5.

[0017] The cavity inside the main housing 1 is divided into a part of the stator cavity 4 and the heat dissipation ribs 5.

[0018] A retaining ring 6 is arranged between the stator cavity 4 and the heat dissipation ribs 5 for limiting. When the stator is installed, it can play a role in restricting the stator to be installed in place, without worrying about the stator not being installed in place or being installed too far during installation.

[0019] A plurality of heat sinks 3 are evenly distributed on the outer peripheral surface of the main housing 1.

[0020] A machine base 2 is arranged below the main housing 1, and a junction box 8 is arranged above.

[0021] The beneficial effects of the present utility model are as follows:

[0022] A plurality of heat dissipation rings are arranged on the inner side of the end portion, so that the heat can be concentrated, and heat dissipation can be achieved more quickly according to the principle of heat transfer; the design of the retaining ring enables the stator to quickly find the defined position during installation and prevents improper installation, greatly facilitating the installation of the stator.
