Description

Technical Field

[0001] The utility model belongs to the technical field of motors, and in particular relates to a plastic-sealed motor. Background Art

[0002] See also Figure 1 Existing iron-cased motors generally consist of a housing and end covers. The stator is pressed into the housing using a tool, and the end cover is then placed on the housing opening and locked with multiple fixing screws. When the housing and end cover are locked, a fixing foot protruding outward from the joint surface of the housing and the end cover is provided with a locking hole. In addition, in order to meet the installation requirements of the customer's application scenario, it is necessary to provide multiple additional mounting feet, and the mounting holes on the mounting feet are provided for installation at the work station of the application scenario. The center of each mounting hole is located on the circumference of the same installation diameter.

[0003] However, the installation diameter of the installation hole of the above-mentioned iron shell motor can only meet one application scenario. For scenarios with different installation diameters, different end cover molds are required, and the versatility is not strong. Utility Model Content

[0027] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0028] See also Figure 1 , the iron sheet structure motor can only have one installation size, and different customer needs require different end cover molds, which is not very universal; the concentricity of the motor is difficult to guarantee, which will seriously affect the motor performance, because the concentricity of the stretched end cover itself is greatly affected by the process and multi-pass mold processing, and the subsequent stator press-fitting and cover closing will cause the motor concentricity to deteriorate, and the concentricity is unstable between 0.05-0.18, and the motor consistency is poor; the appearance is difficult to control, because the end cover is prone to scratches, oil stains, and spots during the entire stretching process and production assembly process, which damage the galvanized layer or electrophoretic layer. If it is in a poor environment, it is easy to rust; the stretched end cover is close to the natural frequency of the iron core, which is prone to resonance, resulting in abnormal vibration and noise; the iron core and enameled wire of this structure are in direct contact with the air, and the iron core is prone to rust, and the enameled wire is oxidized by moisture, which can easily lead to poor inter-turn and voltage resistance, and burn-in during the power-on process of the motor.

[0029] The present application provides a plastic-encapsulated motor, which is described in detail below. It should be noted that the order in which the following embodiments are described does not limit the preferred order of the embodiments of the present application. In the following embodiments, the description of each embodiment has its own emphasis. For parts not described in detail in one embodiment, please refer to the relevant description of other embodiments.

[0030] See also Figure 2 and Figure 3In one embodiment, the plastic-encapsulated motor includes: a plastic-encapsulated shell 1, one end of which is provided with a bearing chamber 11 and the other end of which is provided with an opening 12; an iron core 2, located inside the plastic-encapsulated shell 1; a plurality of first mounting feet 3, arranged in a circular array on the outer wall of the plastic-encapsulated shell 1; and each first mounting foot 3 is provided with a first mounting hole 31, and the center of the plurality of first mounting holes 31 is located on the first circumference 100; a plurality of second mounting feet 4, arranged in a circular array on the outer wall of the plastic-encapsulated shell 1; and each second mounting foot 4 is provided with a second mounting hole 41, and the center of the plurality of second mounting holes 41 is located on the second circumference 200.

[0031] In this embodiment, by adopting a plastic-sealed shell, the screw holes for fixing the shell and the end cover are eliminated, and this position can be used as another set of mounting holes, thereby meeting various customer installation requirements, that is, by setting mounting holes on different circumferences, different installation scenarios can be adapted.

[0032] In addition, the surface of the plastic-encapsulated motor is smooth and consistent, and it will not rust when stored or used in any complex environment, which will affect the overall beauty and service life of the motor. The plastic-encapsulated material and the iron core are integrated into one, and there is no common film effect between the stator and the plastic-encapsulated body. At the same time, due to the different materials, there will be no close frequencies, and no resonance between the motor body and the customer's mounting plate, thereby fundamentally improving the motor noise.

[0033] Furthermore, the first mounting foot 3 and the second mounting foot 4 may be spaced apart.

[0034] Optionally, end surfaces of the first mounting foot 3 and the second mounting foot 4 are located on the same plane.

[0035] Optionally, a gasket groove 32 is provided on the outer periphery of the end portion of the first mounting hole 31 .

[0036] In this embodiment, in the application scenario of the first mounting hole 31 , a washer can be inserted into the washer groove 32 .

[0037] Optionally, the diameter of the first circle 100 is 99 mm; the diameter of the second circle 200 is 96 mm.

[0038] Optionally, the thickness of the first mounting foot 3 and the second mounting foot 4 is 9 mm.

[0039] Optionally, the diameter of the first mounting hole 31 and the second mounting hole 41 is 5 mm.

[0040] In one embodiment, referring to the table below, the BMC shell of the plastic-encapsulated motor is injection-molded together with the iron core and the bearing chamber. The concentricity is ensured by the mold core and can be controlled within 0.05 with good consistency.

[0041]

[0042] In one embodiment, the plastic-encapsulated motor avoids direct contact between metal components and the possibility of resonance, and all major installation dimensions are guaranteed by the mold, thereby improving product precision and fundamentally improving the important noise and vibration indicators of the motor, as shown in the table below.
