This article discusses a field case involving persistent axial vibration on an electric motor despite acceptable performance during decoupled workshop testing. The discrepancy prompted a full diagnostic investigation, including bump testing, modal analysis and structural reinforcement. http://admin.hydrocarbonprocessing.com/news/2026/06/abb-introduces-higher-power-sd200-841-severe-duty-motor-line/ http://admin.hydrocarbonprocessing.com/news/2026/05/yuchai-introduces-its-first-high-pressure-direct-injection-pure-ammonia-internal-combustion-engine-for-heavy-duty-commercial-vehicles/ China Yuchai International has introduced its first high-pressure, direct-injection internal combustion engine capable of operating entirely on ammonia and designed for heavy–duty commercial vehicles. http://admin.hydrocarbonprocessing.com/news/2026/03/us-sues-california-over-zero-emissions-vehicle-greenhouse-gas-rules/ The U.S. Transportation Department sued the California Air Resources Board (CARB) in U.S. District Court in California over vehicle rules that remain in place after President Donald Trump signed legislation last year to overturn California’s Advanced Clean Cars II rules that aim to phase out new gasoline-powered cars by 2035. http://admin.hydrocarbonprocessing.com/news/2026/02/trump-epa-ends-emissions-limits-for-us-automakers-state-rules-lawsuits-could-follow/ Trump's Environmental Protection Agency (EPA) on Thursday finalized its repeal of the "endangerment finding" for vehicles, a 2009 determination that greenhouse gas emissions endanger human health. http://admin.hydrocarbonprocessing.com/magazine/2026/january-2026/maintenance-reliability-and-inspection/mitigating-structural-resonance-in-an-electric-motor-support-a-field-case-study/ http://admin.hydrocarbonprocessing.com/magazine/2025/november-2025/maintenance-reliability-and-inspection/mitigate-electrical-discharge-in-vfd-motors-best-practices-for-bearing-protection/ http://admin.hydrocarbonprocessing.com/news/2025/11/shell-insights-behind-the-rise-of-lng-trucks-in-china/ http://admin.hydrocarbonprocessing.com/news/2025/11/digital-exclusive-mitigating-structural-resonance-in-an-electric-motor-support-a-field-case-study/ Rotating equipment operating near structural natural frequencies is prone to resonance, resulting in elevated vibration levels and potential long-term damage.
