| Summary: | 碩士 === 國立虎尾科技大學 === 車輛工程系碩士班 === 103 === The purpose of this paper is to analyze the model of two high-speed induction motor. We used Cero Parametric cartography software to construct the 3-D solid model combined with finite element analysis software ANSYS Workbench for analysis conducting modal analysis.
The main purpose of this thesis is to reduce the vibration of the motor during operation and to improve its structure from resonance.
Modifying counterweights, labyrinth cover, shaft length and other places by results of the initial analysis. From other analysis result we can know increasing motor length and parts thick making natural frequency to down. Relatively, shorten shaft length, parts thick making natural frequency to raise.
Finally, natural frequency have raise but not reach goal frequency 283.333 Hz. Thought change the rotor and the stator material can obtain higher natural frequency.
