Sunvim Motor
In the modern industrial landscape, the efficiency of power transmission is no longer just about the internal electromagnetic design of a motor, but its mechanical integration within complex machinery. The B35 mounting configuration—a hybrid design featuring both foot-mounting (IM B3) and flange-mounting (IM B5)—has emerged as the gold standard for high-stability, heavy-duty applications. At Shandong Sunvim Motor Co., Ltd., we have spent six decades refining this specific geometry to meet the rigorous demands of Industry 4.0.
Dual-fixation systems significantly reduce axial vibration, extending bearing life by up to 40% compared to single-mount alternatives.
Compatible with standard IEC frames, allowing seamless retrofitting in mining, ventilation, and maritime pump systems.
Designed for IE3, IE4, and IE5 ultra-high efficiency standards, minimizing energy loss through superior mechanical alignment.
Currently, the global industrial motor market is undergoing a paradigm shift toward "smart decentralization." In regions like the European Union and Southeast Asia, there is an increasing demand for motors that can handle high radial loads while maintaining precise alignment with gearboxes. The Discount B35 Mounting Factory model pioneered by Sunvim addresses the critical gap between high-cost European engineering and low-durability generic alternatives. By leveraging large-scale automated production, we provide "Information Gain" to our partners—offering not just a product, but a technical blueprint for operational longevity.
Established in 1963, Shandong Sunvim Motor Co., Ltd. (formerly Weifang Electric Machinery Factory) represents the pinnacle of Chinese motor manufacturing expertise. With a capital investment of 220 Million RMB and a 68,000 m² state-of-the-art facility, we are not just a supplier; we are an institution of mechanical research.
The future of B35 Mounting products lies in the integration of Digital Twins and Smart Sensors. Sunvim is currently developing a new line of IE5 Synchronous Reluctance Motors that feature embedded thermal and vibration sensors within the B35 flange housing.
Implementation of nano-crystalline cores and high-grade copper windings to reach 97%+ efficiency ratings, surpassing standard IEC requirements.
Hybrid liquid-air cooling systems for B35 motors used in enclosed spaces like ship engine rooms or deep-well mining operations.
Establishing regional maintenance hubs in Germany, Singapore, and Australia to provide real-time technical support and spare part availability.
Our B35 motors are not mere components; they are central to large-scale infrastructure. In Metallurgy, they drive high-torque rollers; in Agricultural Irrigation, they power high-capacity pumps across thousands of hectares; in Shipbuilding, they meet DNV and ABS standards for marine propulsion and auxiliary systems.

B35 mounting provides dual support—feet for weight-bearing and a flange for rigid motor-to-gearbox coupling. This significantly reduces radial shaft run-out and is essential for applications where high torque is transmitted through a flange connection.
We utilize a Three-Dimensional Coordinate Measuring Instrument to ensure every flange and foot mounting hole aligns with IEC 60034 standards within a 5-micron tolerance. Each motor undergoes full-load type testing at our specialized center.
Yes. With certifications from DNV, ABS, and CCS, our B35 motors are specifically engineered with anti-corrosion coatings and IP55/IP66 protection for saltwater environments and heavy industrial use.
By integrating the entire supply chain—from the Sunvim Group's raw material sourcing to our automated machining—we eliminate mid-tier markups, offering premium IE4 technology at factory-direct pricing without compromising on E-E-A-T principles.
