Technical SpecificationsVietnam has emerged as one of the most dynamic manufacturing hubs in Southeast Asia. Driven by massive foreign direct investment (FDI) and a strategic shift toward heavy industries, the country is undergoing a profound industrial transformation. Key sectors such as cement production, steel metallurgy, mining, chemical processing, and large-scale wastewater treatment are expanding at an unprecedented rate.
Under Vietnam's newly approved Power Development Plan 8 (PDP8), there is a strong national mandate to improve energy efficiency and reduce carbon emissions across all industrial sectors. This regulatory shift has made high-efficiency medium and high voltage three-phase induction motors critical assets for modern Vietnamese factories. By upgrading to premium efficiency motors, industrial operators can significantly reduce power consumption, stabilize grid loads, and lower operational overhead.
Operating high-power machinery in Vietnam presents unique environmental challenges. The hot, humid tropical climate, coupled with high coastal salinity in regions like Hai Phong and Da Nang, demands electric motors with superior insulation, robust ingress protection (IP55/IP56), and highly efficient cooling systems (such as IC411, IC611, or IC81W). Shandong Sunvim Motor Co., Ltd. specializes in engineering customized MV/HV motors that are fully tropicalized to withstand these harsh operating conditions, ensuring uninterrupted performance and extended service life.
Shandong Sunvim Motor Co., Ltd. represents the pinnacle of industrial motor innovation, backed by over 60 years of manufacturing excellence.
Following a strategic corporate transformation in 2022, we have established a high-standard, modernized production ecosystem tailored for the future of global industry. Backed by the powerful resources of Sunvim Group—a multi-billion RMB conglomerate—Shandong Sunvim Motor Co., Ltd. benefits from strong financial stability and strategic growth. Our expansive facilities house over 400 sets of advanced manufacturing, precision testing, and automated supporting equipment, driving our global distribution and dedicated customer service.
Precision engineering requires advanced machinery. We invest heavily in state-of-the-art technology to ensure every motor meets the highest global standards.
Six decades of continuous growth, technical innovation, and strategic expansion.
Gaomi Electric Appliance Factory was established, laying the foundation for our electric motor manufacturing expertise. In 1988, the company was renamed Weifang Electric Machinery Factory.
Mr. Sun, then the factory director, left Gaomi Electric Appliance Factory and set up Gaomi Towel Factory, which would grow to become the predecessor of the multi-billion RMB Sunvim Group.
Weifang Electric Machinery Factory was strategically acquired by Sunvim Group, leading to the establishment of Shandong Sunvim Electrical Machinery Co. Ltd.
A brand new, highly modernized factory was completed in the Sunvim Industrial Park, and the company was officially renamed Shandong Sunvim Motor Co. Ltd., launching a new era of global expansion.
Our motors are designed, tested, and certified to meet the most stringent international standards, ensuring seamless integration into global projects.

Vietnam's high ambient temperatures (often exceeding 40°C in summer) and relative humidity (frequently above 90%) require motors with Class F or Class H insulation systems, limited to Class B temperature rise. Anti-condensation space heaters must be installed to prevent moisture accumulation in the windings during shutdown. Additionally, high-quality tropicalized varnish and rust-resistant coatings are essential to prevent corrosion, especially in coastal industrial zones.
Our motors are designed and tested in strict accordance with IEC 60034-30-1 standards, which align directly with Vietnam's TCVN 7540 energy efficiency regulations. We offer IE2, IE3, and ultra-high efficiency IE4 three-phase induction motors. Each motor is accompanied by comprehensive type-test reports from our CNAS-certified testing laboratory, ensuring seamless customs clearance and compliance verification in Vietnam.
Y series (IP23) motors are open-type, relying on ambient air for direct cooling; they are only suitable for clean, dry indoor environments. YKK series (IP54/IP55) motors feature an air-to-air heat exchanger, protecting the internal components from dust and moisture, making them ideal for cement and mining industries in Vietnam. YKS series motors use air-to-water heat exchangers, offering superior cooling efficiency and lower noise, perfect for power plants or steel mills where a reliable industrial water supply is available.
Yes, all our MV/HV motors can be customized for VFD operation. To protect the motor from high-frequency voltage spikes (dV/dt) and shaft currents common in VFD systems, we equip VFD-fed motors with reinforced corona-resistant insulation, insulated bearings on the non-drive end, and grounding brushes. This ensures stable operation across the entire speed range and prevents premature bearing failure.
Our marine-duty three-phase induction motors (Y-H series) are fully certified by major international maritime classification societies, including the China Classification Society (CCS), American Bureau of Shipping (ABS), and Det Norske Veritas (DNV). These motors feature specialized marine-grade anti-corrosive paint, vibration-resistant construction, and IP56 or higher protection ratings to withstand the harsh marine environment.
For standard medium/high voltage motors, the production lead time is typically 45 to 60 days. Highly customized engineering projects may take 75 to 90 days. Shipping from Qingdao Port to Hai Phong Port in northern Vietnam takes approximately 7 to 10 days, while shipping to Cat Lai Port in Ho Chi Minh City takes about 10 to 12 days. We handle all export documentation, including Certificate of Origin (Form E) to allow tariff-free import under the ASEAN-China Free Trade Agreement.
