Description

Technical Field

[0001] This utility model relates to the field of motor heat dissipation technology, specifically to a heat dissipation device for a motor equipped with an encoder and the motor thereof. Background Technology

[0002] An electric motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction, and it is widely used in various applications requiring energy conversion. With the continuous development of electrical automation technology, encoders are increasingly being used in motor control. Because motors often operate in complex environments such as oil and humidity, encoders used in conjunction with motors need to consider moisture and seepage prevention. Therefore, encoders are often installed in IP67-rated, sealed environments. Consequently, existing encoder technologies suffer from the technical problem of not being able to dissipate heat through the motor's fan. When the encoder's operating environment temperature is too high, its operating efficiency decreases, which in turn affects the motor's performance. The encoder's operating environment temperature is affected by two factors: the encoder's own heat generation during operation and the significant heat generated by the motor during operation. These factors result in encoders experiencing efficiency issues due to increased operating environment temperature in the aforementioned application scenarios. Utility Model Content

[0003] To address the technical problem of low operating efficiency of encoders in the prior art due to the susceptibility of encoders to ambient temperature during operation, a heat dissipation device and motor for a motor equipped with an encoder are provided, which at least have the advantages of the encoder being less affected by ambient temperature and having stable and reliable operating performance.

[0022] Furthermore, the motor includes a protective cover, and the encoder is housed within the protective cover.

[0023] Furthermore, at least a portion of the heat-conducting element extends beyond the protective cover.

[0024] In summary, this utility model provides a heat dissipation device for a motor equipped with an encoder and the motor thereof. The main technical concept of the heat dissipation device has at least the following advantages: by combining heat insulation and heat conduction components, it isolates the heat from the motor while simultaneously dissipating heat from the encoder, thereby ensuring that the heat generated by the motor does not affect the operation of the encoder and can dissipate the heat generated by the encoder, reducing the impact of heat on the encoder's working efficiency, and thus ensuring that the encoder and the motor controlled by the encoder are in a continuous high-performance state. At the same time, the combined use of heat insulation and heat conduction components also has advantages such as low cost, convenient application, and small footprint in the motor.

It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0032] The main technical concept of this utility model is to combine the heat insulation component 110 and the heat conduction component 120 to achieve heat insulation for the motor 3 while also dissipating heat from the encoder 2, thereby ensuring that the encoder 2 and the motor 3 controlled by the encoder 2 are in a continuous high-performance state.

[0033] For further details, please see Figure 1 The diagram shown is a structural schematic of a heat dissipation device 1 for a motor 3 equipped with an encoder 2, according to an embodiment of the present invention.

[0034] Example 1

[0035] The present invention provides a heat dissipation device 1 for a motor 3 equipped with an encoder 2, comprising: a heat insulation member 110, and a heat-conducting member 120 disposed in contact with the heat insulation member 110; the heat insulation member 110 is disposed in contact with the heat dissipation part of the motor 3; the heat-conducting member 120 is disposed in contact with the heat dissipation part of the encoder 2.

[0036] Optionally, the insulation 110 may include rock wool, silicate, glass fiber, or aerogel.

[0037] Optionally, the heat-conducting component 120 includes a metal component 121 and a circulating heat dissipation component 122;

[0038] Metal component 121 is used to at least partially cover the heat dissipation part of encoder 2;

[0039] The circulating heat dissipation component 122 is laid on the outer surface of the metal component 121 by means of a laying method;

[0040] The circulating heat dissipation component 122 includes heat dissipation pipes and fluid filling the heat dissipation pipes.

[0041] Optionally, the metal component 121 may include metals with good thermal conductivity, such as copper and aluminum.

[0042] For example, please see Figure 2 The image shown is a plan view of a metal component 121 and a circulating heat dissipation component 122 provided in an embodiment of this utility model. Figure 2 The central circulation heat dissipation component 122 is a vertically arranged heat dissipation pipe laid on the outer surface of the metal component 121, thereby exchanging heat accumulated in the metal component 121. It is worth explaining that the circulation heat dissipation pipe can come in various forms, such as a ventilated cavity, a coil, etc.

[0043] Furthermore, by bonding or fastening, the heat insulation component 110, the circulating heat dissipation component 122, and the metal component 121 are integrated in sequence, thereby improving the overall integrity of the heat dissipation device 1 and making it easy to assemble and replace.

[0044] Optionally, all metal components 121 include a heat dissipation structure 121a.

[0045] Furthermore, the heat dissipation structure 121a is configured as a folded type. For an example, please refer to [link to example]. Figure 1 As shown, the heat dissipation structure 121a is wavy in shape.

[0046] For further details, please see Figure 3 The diagram shown is a structural schematic of a motor 3 with heat dissipation function provided in an embodiment of the present invention.

[0047] Example 2

[0048] Based on Embodiment 1, this utility model provides a motor 3 with heat dissipation function, including a heat dissipation device 1, a rotor 310 and an encoder 2 connected to the rotor 310; a heat insulation member 110 is disposed between the rotor 310 and the encoder 2 and completely isolates the encoder 2; a heat conduction member 120 at least partially covers the encoder 2.

[0049] Furthermore, the motor 3 includes a protective cover 330, and the encoder 2 is housed in the protective cover 330.

[0050] Furthermore, at least a portion of the heat-conducting element 120 extends out of the protective cover 330.

[0051] Optionally, the portion of the heat-conducting element 120 that outputs to the protective cover 330 includes a heat dissipation structure 121a, through which heat exchange between the interior of the protective cover 330 and the external environment is achieved.

[0052] Optionally, the heat dissipation structure 121a can be configured as a folded type to enhance the heat exchange area between the heat dissipation structure 121a and the external environment.

[0053] Based on the optional embodiments provided in the first and second aspects, the working principle of this utility model is as follows: During the operation of the motor 3 and the encoder 2, since the encoder 2 is mounted on the stator 320, and the stator 320 itself does not generate heat, the heat generated by the rotor 310 mainly interferes with the encoder 2. Therefore, the heat insulation component 110 of the heat dissipation device 1 is fitted against the rotor 310 to isolate the heat generated by the rotor 310. At the same time, its heat conducting component 120 is fitted against the encoder 2 to exchange the heat generated by the encoder 2.
