Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a synchronous motor with a water accumulation prevention structure. Background Art

[0002] Traditional fans are mostly driven by three-phase or single-phase asynchronous motors. Although asynchronous motors are low in cost, simple in structure, and easy to maintain, they have low efficiency and power factor, and large losses. At the same time, the flow regulation of fans and water pumps driven by such motors is usually completed by adjusting dampers and valves, so there is a serious waste of electricity. People use frequency converters to adjust the speed of asynchronous motors in fans and water pumps to adjust their flow, achieving considerable energy-saving effects, but the cost of frequency converters is high, and the low efficiency of asynchronous motors themselves still exists.

[0003] The AC permanent magnet synchronous motor is a motor that can be started directly in a 50Hz three-phase AC environment. It is a high-efficiency and energy-saving motor made by replacing traditional electric excitation with rare earth permanent magnet materials. It not only has the advantages of simple structure, reliable operation, and low heat generation of general permanent magnet motors, but also has the remarkable characteristics of small size, light weight, low loss, and high efficiency. It can achieve high performance that is difficult to achieve with traditional electric excitation motors.

[0004] However, in some usage environments, water is easily accumulated on the top cover of the synchronous motor driver. If the accumulated water is not discharged in time, it is easy to enter the interior of the driver and affect the performance of the motor over a long period of time. Utility Model Content

[0005] The main purpose of the utility model is to provide a synchronous motor with an anti-water accumulation structure, aiming to solve the technical problem that the top cover of the existing synchronous motor driver is prone to water accumulation, which affects the motor performance over a long period of time.

[0006] In order to achieve the above object, the utility model provides a synchronous motor with a water accumulation prevention structure, which comprises:

[0007] A motor body, the motor body comprising a motor driver and a top cover connected to the motor driver;

[0008] Wherein, a bulge is formed in the middle portion of the outer surface of the top cover, and a plurality of first guide ribs are provided along the bulge to the outer periphery of the top cover.

[0009] Optionally, the cross section of the top cover is arched.

[0010] Optionally, at least part of the first guide ribs are distributed along both sides of the arched top cover.

[0011] Optionally, at least part of the first guide ribs are strip-shaped.

[0012] Optionally, at least some of the first guide ribs are parallel to each other.

[0013] Optionally, a plurality of second flow guide ribs extending in the axial direction are provided on the side surface of the motor body.

[0014] Optionally, the side surface of the motor body is provided with heat dissipation fins extending in the axial direction.

[0015] In the technical solution of the utility model, a protrusion is formed in the middle part of the outer surface of the top cover of the motor driver, and a plurality of first guide ribs are provided along the protrusion to the outer periphery of the top cover. When water falls into the top cover, due to the protrusion provided in the middle part thereof, the accumulated water will flow out of the top cover along the first guide ribs under the action of gravity, thereby effectively preventing the accumulated water from entering the interior of the motor and affecting the motor performance, thereby improving the service life of the motor.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0028] In some usage environments, water is easily accumulated on the top cover of the synchronous motor driver. If the accumulated water is not discharged in time, it is easy to enter the interior of the driver and affect the performance of the motor over a long period of time.

[0029] In view of this, the utility model proposes a synchronous motor with an anti-water accumulation structure. Figure 1-5 For an embodiment of a synchronous motor with a water accumulation prevention structure provided by the utility model, please refer to Figure 1-5 The synchronous motor 100 with anti-water accumulation structure includes a motor body 1, the motor body 1 includes a stator and a rotor, and a motor driver 11 connected to the stator and the rotor. The motor driver 11 is provided with electronic components such as a power module and a circuit board, and is also provided with a detachable top cover 12 for sealing, so as to facilitate the installation and maintenance of the driver. A protrusion 121 is formed in the middle part of the outer surface of the top cover 12, and a plurality of first guide ribs 122 are provided along the protrusion 121 to the outer periphery of the top cover 12.

[0030] In the present technical solution, a protrusion 121 is formed in the middle part of the outer surface of the top cover 12 of the motor driver 11, and a plurality of first guide ribs 122 are provided along the protrusion 121 to the outer periphery of the top cover 12. When water falls into the top cover 12, due to the protrusion 121 provided in the middle part thereof, the accumulated water will flow out of the top cover 12 along the first guide ribs 122 under the action of gravity, thereby effectively preventing the accumulated water from entering the interior of the motor and affecting the motor performance, thereby improving the service life of the motor.

[0031] See also Figure 4 and Figure 5 In one embodiment of the present invention, the top cover 12 is approximately circular, and in mutually parallel cross sections, the outer surface of the top cover 12 is arched, that is, the middle portion is raised.

[0032] Further, on the basis of the top cover 12 having an arched cross section, in order to increase the flow speed of the accumulated water and prevent the accumulated water from flowing turbulently, please refer to Figure 3 In one embodiment of the present invention, each of the first guide ribs 122 is respectively distributed on both sides of the outer surface of the arched top cover 12 and is symmetrical to each other.

[0033] Furthermore, part of the first guide ribs 122 are in a strip shape, and another part of the first guide ribs 122 are in a bent shape, both of which can have a good guide effect on the outer surface of the arched top cover 12 .

[0034] In order to evenly drain the accumulated water, in one embodiment of the present invention, at least some of the first guide ribs 122 are parallel to each other.

[0035] When the accumulated water flows from the top cover 12 to the side surface of the motor body 1, in order to increase the flow speed of the accumulated water and prevent the accumulated water from flowing turbulently, please refer to Figure 1 In one embodiment of the present invention, the side surface of the motor body 1 is provided with a plurality of second flow guide ribs 13 extending in the axial direction, so that the accumulated water can flow quickly along the side surface of the motor body 1. It should be understood that the axial direction here refers to the direction along the rotating shaft of the motor.

[0036] In some environments, such as fans, to improve the heat dissipation of the motor, please refer to Figure 1 In one embodiment of the utility model, the side surface of the motor body 1 is provided with heat dissipation fins 14 extending in the axial direction, so that the axially flowing wind can take away the heat generated by the motor.

[0037] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
