Direct supply from state-of-the-art manufacturing plants, engineered for ATEX, IECEx, CE, and UL global standards.
60+ Years of Manufacturing Leadership & Engineering Excellence
Xi’an Lite SIMO Motor Co., Ltd stands as one of the preeminent electric machine manufacturers in China. Specializing in the end-to-end design, mechanical processing, vacuum pressure impregnation (VPI) insulation, precision assembly, and rigorous testing of large, medium, and small-scale motors, SIMO ranks at the top of the mechanical industry scale.
With a strategic focus on energy-efficient systems, high-voltage equipment, and intrinsically safe explosion-proof motors (such as the YBX3, YBX4, and YBX5 Series), SIMO integrates dynamic scientific research with strict quality control. Our motors power critical operations across metallurgy, petrochemical refinement, oil and gas extraction, municipal water resources, and heavy mining infrastructure worldwide.
A continuous legacy of research, acquisition, and expansion over six decades.
SIMO Motor was established under state guidance to support China's primary industrial reconstruction efforts, laying down the baseline for industrial motor development.
Moved operations to Xi'an City, expanding mechanical production lines and introducing advanced casting and machining technologies.
Re-organized after strategic government acquisitions and integrations to form a single, centralized motor design, testing, and production powerhouse.
Successfully reformed from a state-owned factory into a limited liability company, injecting private capital and modern corporate governance.
Established as a comprehensive conglomerate with 14 specialized subsidiaries controlling upstream and downstream components, raw materials, and maintenance operations.
Relocated to a newly constructed, state-of-the-art advanced production complex featuring climate-controlled workshops, automatic testing bays, and high-precision CNC toolings.
Pivoted towards tech-intensive machinery, introducing multi-frequency driving controls, high-voltage synchronous options, and low-temperature explosion-proof models.
Continuing the journey as one of the world's most trusted manufacturers. Driving energy transition with IE4/IE5 premium efficiency and smart ATEX/IECEx certified explosion-proof technologies.
How Simo utilizes localized clusters and advanced engineering to deliver cost and stability advantages.
At our main production facility, Tech Full Simo Motor operates over 1,172 sets of advanced equipment. The production cycle incorporates cutting-edge vertical machining centers, precision cylindrical grinding mills, digital balancing rotors, and automatic electrostatic painting stations. By managing key stages of the supply chain internally—from initial mold creation to specialized electromagnetic steel stamping—we neutralize external pricing volatility.
A comprehensive review of engineering standards, safe zones, and future intelligence.
In hazardous industrial environments, safety is not merely about shielding electrical components; it requires a deep structural integration of physics, thermodynamics, and fluid dynamics. ATEX and IECEx compliance mandates that any electrical equipment operating in Zone 1 or Zone 2 (gas) and Zone 21 or Zone 22 (dust) must prevent any internal ignition or electrical arc from escaping into the external combustible atmosphere.
Designed to withstand the internal pressure of an explosion. The flamepaths (thread, flanged, or cylindrical joints) cool the escaping combustion gases below the auto-ignition temperature of the external atmosphere before they reach the outside of the motor casing.
Applies mechanical and electrical design enhancements to prevent the generation of hot surfaces, sparks, or arcs under normal operations and specific overload conditions. Utilizes specialized insulation and tight terminal spacing.
Features highly sealed casings rated IP65/IP66 to prevent combustible dusts (like coal, grain, or sulfur) from penetrating into the hot interior, ensuring surface temperatures stay well below dust smoldering limits.
The next generation of explosion-proof technology aligns with the **IE5 Ultra-Premium Efficiency** standards. SIMO’s development team is targeting several key technical milestones:
Tailored engineering alignments across key global infrastructure segments.
Operating in continuous Zone 1 environments requires absolute reliability. Our **YBX3, YBX4, and YBX5 Series** low/high voltage explosion-proof motors are designed to drive continuous pumps, fans, and compressors in environments containing hydrogen, ethylene, and hydrocarbon fumes.
Underground mines present combinations of methane gas and highly abrasive coal dust. The **YBK3 Series** flameproof three-phase motors are specifically certified for Group I mining environments, utilizing special protection barriers and heavy mechanical reinforcement.
Driving raw material millings, massive air separators, and blast furnace blowers requires high power and starting torque. Our **TDMK series synchronous motors** and **YRKK wound rotor high-voltage motors** deliver reliable performance for large mechanical loads.
Approved by leading testing authorities to guarantee seamless compliance across global markets.
Quality control at Xi'an SIMO Motor is managed under strict compliance protocols. We have achieved ISO 9001 Quality System Certification, European Union CE, United States UL, and Russian Federation GOST certifications. This structured quality management process ensures traceability from raw steel coils to the final dynamically balanced rotor assembly.
Simplified logistics, customized mechanical shafts, and ongoing support for international engineering projects.
Selecting a motor partner for hazardous areas requires evaluating global logistics capabilities alongside technical specifications. Xi'an SIMO Motor provides comprehensive support to international procurement teams through:
