電気自動車用モータの不釣合い応答に及ぼすエアギャップの影響

Key Points

• The research aims to understand how the air gap in electric vehicle motors affects vibration phenomena at high rotation speeds.
• Utilized mass-produced electric vehicle motors for testing.
• Measured vibration acceleration and rotor center displacement.
• Varied the air gap and alignment to assess their effects.
• Conducted experiments at high rotational speeds.
• Identified new vibration phenomena at high speeds not seen at low speeds.
• Demonstrated how changes in air gap and alignment directly influence vibration response.
