Nominal torque: M = 1.69 N\(\cdot\)m  
Nominal speed: 2650 rpm  
Based on the data, it can be concluded that the calculations performed with the RMxprt software were accurate. In future investigations of the dynamics of induction motors using

The investigation of the dynamics of the system of moving elements of an asynchronous motor is crucial due to its significant impact on the vibration state of the entire motor. The dynamic properties of the whole machine play a vital role during the development of the motor parameterization test bench. The natural vibrations of the structure are calculated to prevent the operating frequencies from aligning with the resonance frequencies. The purpose of this calculation is to conduct a modal analysis of the motor rotor in conjunction with other moving elements of the system while accounting for the gyroscopic effect. A complete CAD model of the induction motor, utilizing finite element analysis, has been generated. The first step of the calculation involves converting the necessary elements into the Ansys software. Figure 13 displays the CAD model in the SolidWorks software. When importing files in.step or.parasolid format, a problem may arise such as artifacts on the edges of circles, overhangs, and roundings. To solve these problems, the original geometry must be corrected. To accomplish this, a body operation element is created on the Create tab, and Simplify is selected on the type table. All assembly elements are then marked and renamed according to their purpose. This completes the part preparation for calculations. Figure 15 shows avoiding artefacts on parts. Materials must be assigned to all components. The rotor, which is a composite part, will include several materials. The bearing material will be assigned according to the bearing datasheet of the medium series, and the shaft material will be assigned according to the motor datasheet. The impeller will be assigned polycaprolactone. Contact surfaces are then checked or assigned. As the rotor is a single construction, there will be no contact surface assignment to the shaft. This is not a critical aspect since the entire rotor will be calculated as one unit. Figure 16 shows assigning contact surfaces. The next step is to create a mesh of objects to investigate. The more precise the polygonal mesh, the more accurate the calculation will be, but the more processing power it will require. Attention must be paid to element joints, rounded surfaces, and surfaces with complex geometry to make local adjustments to the mesh and avoid interference. Figure 17 shows creating a polygonal mesh of objects. Figure 16: Assigning contact surfaces. Figure 15: Avoiding artefacts on parts. After defining and editing the mesh, it is necessary to establish boundary conditions by setting rigid terminations on the raceways of the inner rings of the bearings. Rotor dynamics simulations can be conducted in two different reference systems: stationary and rotating. Ansys considers the gyroscopic effect by using a damping matrix, where a negative value represents a stable oscillation form, and a positive value corresponds to an unstable one. The imaginary part indicates the natural frequency, including damping. Despite using a damping matrix to account for the gyroscopic effect, no energy dissipation occurs in the absence of specified damping in the model. Thus, all real parts of complex frequencies are set to zero. To initiate the calculation, one needs to select Solve from the context menu of the modal item.
