From a state-owned enterprise to a global powerhouses in electrical motor engineering and supply.
SIMO Motor was established and led by the government. By 1957, operations moved to the new major manufacturing plant in Xi'an city, cementing its place in China's industrial core.
Renamed as Xi'an Motor Factory after series of strategic acquisitions and integration. In 1999, reformed into a limited liability company from a state-owned factory.
SIMO Motor Group established with 14 subsidiaries. Relocated to a state-of-the-art, advanced high-tech facility in 2006. Rebranded as Tech Full Simo Motor in 2009.
Still leading the path as one of the best motor manufacturers globally, expanding compliance with UL, CE, GOST standards for high/low voltage flanged motor systems.
Delivering high-efficiency motors from 0.35kW up to 25,000kW for diverse industrial requirements.
Engineered for major utilities, petrochemical infrastructure, and mine ventilation. Standardized to meet premium IE4 and IE5 standards.
Hazardous area motors certified for oil fields, chemical operations, dust environments, and underground coal extraction.
Designed for heavy rolling mills, rubber extruders, and marine propulsion systems demanding precise control.
Industrial insight into why flange mounting (B5, B14, B35) is crucial for precision and system longevity.
In heavy industrial machinery, the alignment between the driving motor and the driven system (such as pumps, gearboxes, and compressors) determines the operational lifespan of the entire system. Flanged motors bypass the alignment vulnerabilities associated with standard foot-mounted setups by utilizing a machined flange interface that registers directly onto the driven equipment.
By using precision-engineered flanged induction motors, shaft misalignments are reduced to less than 0.05 mm. This precise alignment eliminates high-frequency radial vibration, significantly extending the life of the bearings (such as SKF or FAG bearings used in our motors) and protecting the mechanical seals of connected gearboxes and fluid pumps.
How SIMO combines China's advanced manufacturing infrastructure with rigorous quality standards.
Sourcing large-scale electric motors and flanged systems requires balanced lead times, structural customization, and competitive cost structures. Xi'an Lite SIMO Motor's advanced industrial facility represents the pinnacle of Chinese heavy mechanical engineering. With over 1,172 sets of advanced equipment, our factory handles everything from automated lamination punching, dynamic rotor balancing, and computer-controlled winding, to state-of-the-art VPI (Vacuum Pressure Impregnation) insulation systems.
This vertical integration allows global procurement managers to benefit from:
Direct access to ultra-premium silicon steel and high-grade copper windings ensures the manufacture of YE5/IE5 ultra-premium efficiency motors with minimal loss characteristics.
Our standard patterns cover over 19,500 specifications. We can easily scale custom shaft dimensions, high-temperature bearings, or special IP ratings (IP55, IP56, IP65, IP66) to meet specific design requirements.
Every high-voltage motor undergoes rigorous full-load and insulation tests before dispatch, ensuring that it meets safety and performance parameters under real industrial conditions.
Meeting international quality benchmarks to ensure seamless integration into localized markets worldwide.
To support global supply chains, our motors comply with major national and international standards. SIMO has successfully passed the ISO9001 Quality System Certification, European Union's CE, United States' UL, Russian GOST, and China's explosion-proof certifications (CQST). Whether you operate in the oil and gas sectors of North America, mining in Australia, or heavy metallurgy in Europe, our products meet local safety requirements, preventing compliance delays at customs or site commissioning.
High-reliability flanged motors designed for critical infrastructure and advanced automation.
B5 and B35 flanged motors are widely used in large-scale vertical drainage pumps, irrigation systems, and municipal water plants. The secure flange interface prevents shaft misalignment during high-thrust load starts.
YB3, YBK3, and YBBP explosion-proof flanged motors are certified for coal mines, petrochemical refineries, and gas handling systems. They ensure reliable operations in environments with explosive gases or flammable coal dust.
Our high-torque Z series DC motors and heavy-duty asynchronous systems drive steel rolling mills, mine hoists, and material handling systems, providing the reliable torque response needed for high-impact loads.
As international energy regulations (like the EU Commission Regulation 2019/1781) tighten, the adoption of ultra-premium efficiency IE5 motors has become standard practice for global buyers. Modern industrial flanged motors are increasingly paired with intelligent variable frequency drives (VFD) and IoT diagnostic sensors. Our YVFE3 and YVFE4 motor series are built to run efficiently under varying load profiles on variable frequency networks, while integrated thermal elements (PT100) and vibration sensors provide remote predictive maintenance capabilities to minimize unplanned downtime.

Expert answers to common engineering, procurement, and installation queries.
B5 flanges feature clearance through-holes with a diameter larger than the motor frame, allowing attachment from the back of the flange. B14 flanges feature threaded holes and are smaller in diameter, perfect for space-constrained installations. B35 motors combine a B5 flange with structural mounting feet to provide support in high-vibration applications.
We design our housings using high-tensile cast iron or welded steel plates, coupled with precision-machined mating surfaces. This construction prevents flange deformation under bending moments, protecting the rotor and bearings from mechanical stresses and vibration.
Yes, our YFB3, YFB4, and YBX5 explosion-proof series are certified for dust environments (Ex tD) as well as gas-hazardous zones. They comply with IECEx and Chinese CQST standards, ensuring safe operation in oil fields, refineries, chemical processing plants, and underground mines.
Absolutely. The YVFE3, YVFE4, and YVFE5 series are designed specifically for VFD operation. They feature reinforced Class F/H insulation and independent cooling fans to prevent overheating at low speeds, ensuring reliable performance across the entire speed range.
