Zusammenfassung: | In this article, a radial-electromagnetic-force-harmonic-oriented design methodology is proposed to suppress motor vibration. In the proposed methodology, the radial-electromagnetic-force harmonics innovatively act as the effective bridge between structural field and vibration performance. And avoiding low-order and large-amplitude radial-electromagnetic-force harmonics is the premise of designing low-vibration permanent magnet (PM) motors. For extensive investigation, a 36-slot/8-pole interior PM (IPM) motor with different winding configurations and variable rotor parameters is chosen as a design example. Then, the vibration suppression methods of lowest nonzero spatial-order shifting in the stator system and dominant-harmonic-amplitude reduction in the rotor system are proposed. Next, the performances of the IPM motor are simulated for validating the proposed methodology. Finally, a prototype motor is fabricated and experimented. Both theoretical derivation and test results are presented to verify the validity of the motor and the proposed design methodology. |
