Pumps can be found installed in a wide variety of equipment.
In recent years, however, the number of situations in which they are close to residential spaces has increased. Therefore, the noise caused by vibration is one of the related problems. In this presentation, the electromagnetic force generated in the stator core and the rotational motion electromagnetic force of the rotor with eccentric rotation are derived by magnetic field analysis. The derived electromagnetic force is then coupled with structural analysis, and the establishment of a method for pump vibration analysis is examined.
