Description

Self-cooling motor without fan blades

Technical Field

The utility model relates to woodworking machinery, in particular to a self-cooling motor without a fan blade.

Background

High-frequency motors used in the woodworking industry generate heat due to high-speed rotating speed. At present, most motors adopt axial flow fans or centrifugal fans to generate internal wind pressure so as to realize internal cooling medium circulation; however, when the motor is a high-speed motor, the noise, vibration and strength of the fan become a bottleneck in the design of the high-speed motor. The conventional solution is to use an externally driven water cooling cycle, but this adds to the complexity of the system.

Disclosure of Invention

In order to overcome one of the defects or shortcomings of the prior art, the utility model provides a self-cooling motor without a fan blade, and the adopted technical scheme is as follows:

the utility model provides a self-cooling motor of no fan blade, includes the casing, with the end cover of casing both ends rigid coupling, set firmly with the stator in the casing, change the pivot of establishing on the end cover, be located the stator, set firmly the epaxial rotor in the pivot, be different with prior art: the cross-section of casing is the rectangle, and circular inner chamber is seted up at the center, and 4 long directions are on a parallel with circular inner chamber axial, link up the heat dissipation channel at casing both ends around circular inner chamber, set up a plurality of heat dissipation holes that communicate with each other with heat dissipation channel at the lateral wall of casing.

Furthermore, the heat dissipation channel comprises a large plane and a small plane which are parallel to the top surface or the bottom surface of the shell, a large vertical surface and a small vertical surface which are parallel to the side surface of the shell, and an arc surface which is concentric with the circular inner cavity.

Furthermore, a plurality of heat dissipation fins with the length direction parallel to the axial direction of the circular inner cavity extend inwards on the large plane, the small plane, the large vertical surface, the small vertical surface and/or the cambered surface of the heat dissipation channel.

Compared with the prior art, the utility model can achieve the purpose of autonomous heat dissipation through the unique heat dissipation channel and the heat dissipation holes, does not need externally driven water cooling circulation, greatly reduces noise and reduces the overall cost.

Detailed Description

In the description of the present invention, it is to be understood that the terms "left", "right", and the like, indicate orientations or positional relationships based on those shown in the drawings, and are used only for convenience in describing the present invention and for simplicity in description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated. The terms "first", "second", etc. are used merely to distinguish different elements and should not be construed as limiting the utility model.

In the description of the present invention, unless otherwise specified, "a plurality" means two or more unless explicitly defined otherwise.

In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally connected; unless the movable connection is explicitly defined as a detachable connection. These connections are conventional in the art and those skilled in the art will understand the specific meaning of the above terms in the present invention according to the specific situation.

A self-cooling motor that no fan blade as shown in the figure, including casing 1, with the end cover 2 of 1 both ends rigid coupling of casing, set firmly with the stator in the casing, change and establish pivot 3 on end cover 2, be located the stator, set firmly the rotor on pivot 3, the cross-section of casing 1 is the rectangle, circular inner chamber 11 is seted up at the center, set up 4 length directions and be on a parallel with circular inner chamber axial, link up the heat dissipation channel 12 at 1 both ends of casing around circular inner chamber 11, set up 4 and the communicating louvre 13 of heat dissipation channel 12 at the lateral wall of casing 1. The heat generated in the motor is conducted into the heat dissipation channel 12 through the shell and then conducted into the atmosphere through the heat dissipation holes 13, so that the purpose of heat dissipation is achieved. Does not need externally driven water cooling circulation, greatly reduces noise and reduces the whole cost.

The heat dissipation channel 12 comprises a large plane 15 and a small plane 16 parallel to the top surface or the bottom surface of the shell 1, a large vertical surface 17 and a small vertical surface 18 parallel to the side surface of the shell 1, and an arc surface 19 concentric with the circular inner cavity 11. This maximizes the area of the heat dissipation channel 12.

The small plane 16 and the small vertical surface 18 of the heat dissipation channel 12 extend inwards for 1 heat dissipation fin (14) with the length direction parallel to the axial direction of the circular inner cavity. The heat dissipation area can be further increased.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
