Description

[0002] In engineering design and simulation analysis, creating an accurate 3D motor model is a crucial step. However, for complex three-phase asynchronous motors such as the YBX series, manufacturers typically only provide limited installation dimensions (such as bolt hole spacing and shaft extension) and overall dimensions (such as total length and height) in their product catalogs. A complete modeling process requires numerous undisclosed details, such as the motor body radius, the specific dimensions of the heat sink fins, the precise thickness of the mounting feet, and the detailed structural dimensions of the junction box.

[0027] Step 3: Use the second geometric dimension of the three-phase asynchronous motor as the modeling dimension of the three-phase asynchronous motor.

[0028] It should be noted that this method is applicable to the modeling and dimensional calculation of YBX series three-phase asynchronous motors (frame sizes 63-560) and motors with similar shapes, such as the YE series, YB series, and YBK series. By analyzing the characteristics of the dimensions (independent variables) provided by the manufacturer and other dimensions (dependent variables), a mathematical relationship between the two types of dimensions (variables) is established. This relationship is then verified through modeling different frame sizes and different types of motors to obtain the final applicable calculation method.

[0029] Specifically as follows: 1. Analyze the relationship between the independent and dependent variables. The dimensional data (hereinafter referred to as "independent variables") obtained in the initial stage of motor modeling are shown in Table 1, and the dimensional data (hereinafter referred to as "dependent variables") that need to be calculated are shown in Table 2.

(6) A uniform base value can be used for the chamfer radius. The chamfer value used in different parts can be adjusted appropriately. (7) Other dimensions required for modeling can be adjusted according to the characteristics of the parts. For example, to enhance the expressive effect of the model, the chamfer radius of the motor head can be 1 times the basic chamfer radius, and the chamfer radius of the tail can be 2 times the basic chamfer radius; the diameter of the shoulder can be 4 / 3 times the diameter of the output shaft, and the thickness of the shoulder can be 1 / 10 of the thickness of the output shaft, etc.
