Browse our top-tier high-voltage, direct current, and explosion-proof motors engineered to meet stringent international standards (IE3, IE4, CE, UL).
As the primary drivers of heavy industrial infrastructure, motores eléctricos (electric motors) account for approximately 45% of global electricity consumption. The industrial landscape is undergoing a massive transformation, driven by decarbonization policies, energy efficiency regulations (such as European Ecodesign Regulations and MEPS globally), and the rapid deployment of automated systems.
Heavy duty industries like mining, oil and gas, metallurgy, water treatment, and power generation are increasingly shifting away from legacy machines to custom, high-voltage induction and synchronous motors. Modern operations demand high reliability in extreme conditions, necessitating specialized configurations such as explosion-proof housings, dust protection, and water-cooled systems.
By establishing strong OEM partnerships directly with top-tier motor factories, global enterprises bypass distribution layers, optimize design characteristics for precise load profiles, and achieve significant reductions in Total Cost of Ownership (TCO).
Our OEM manufacturing integrates the latest standards for energy savings. Upgrading to IE3 and IE4 premium efficiency levels directly correlates with hundreds of thousands of dollars in utility cost reductions annually for high-capacity applications.
Established as a cornerstone of the Chinese mechanical industry, Xi’an Lite SIMO Motor Co., Ltd. stands as a preeminent enterprise specializing in the research, development, and manufacturing of large/medium-sized, high/low voltage AC motors, DC motors, synchronous motors, and explosion-proof motors.
SIMO operates as a comprehensive design-to-service supplier, incorporating motor engineering, mechanical processing, mold fabrication, vacuum pressure impregnation (VPI) insulation, precision assembly, and rigorous load testing. Ranked at the absolute peak of the national motor manufacturing ecosystem in terms of scale and technological capability, the company sustains an aggressive, fast-growing expansion pattern in both domestic and international markets.
Trace our historic evolution from a state-owned foundational facility in 1955 to a global leader in high-performance electrical propulsion systems.
SIMO Motor was established and led by the Chinese government to lay the foundation for national mechanical engineering.
Relocated to a dedicated, expanded manufacturing site in the industrial hub of Xi'an City.
Officially renamed Xi'an Motor Factory following successful strategic mergers and asset integration.
Successfully reformed from a state-owned enterprise into a modern, agile limited liability company.
Formed the SIMO Motor Group, expanding its footprint through 14 specialized subsidiaries.
Moved manufacturing operations to a state-of-the-art, high-tech development facility designed for advanced automation.
Transitioned corporate identity to Tech Full Simo Motor to reflect international technical engineering focus.
Continuing to drive high-voltage AC/DC motor technology forward, cementing our position as a top-tier global exporter.
The concentration of raw material refinement, technical engineering talent, and massive scale optimization makes Chinese motor factories highly competitive. At SIMO Motor, this translates directly into significant efficiency, quality, and economic advantages for our clients:
Proximity to premium silicon steel producers, high-purity copper refineries, and advanced insulation material vendors ensures continuous production flow and reduced base material costs without quality compromise.
Our facilities house over 1,172 sets of high-precision machines. Advanced Vacuum Pressure Impregnation (VPI) lines guarantee class F/H winding insulation, extending motor operational lifespan under harsh duty cycles.
Every motor undergoes thorough testing, including dynamic balancing, winding resistance checks, dielectric breakdown tests, and temperature rise profiling, simulating real-world industrial loads before shipment.
LITESIMO manufactures an extensive catalog of industrial electric motors spanning 34 major series, 1,800 varieties, and 19,500 individual specifications. Our power ratings range from a precise 0.35 kW up to highly specialized 25,000 kW machines.
YX, YXKK, and YXKS high-efficiency series utilize optimized stator laminations and electromagnetic configurations to reduce thermal loss and optimize power factor performance.
YR, YRKK, and YRKS series are ideal for applications requiring high starting torque with low starting currents, such as heavy cranes, crushers, and grinders.
YBX3, YBX4, and YBX5 flameproof series are specifically designed for hazardous environments containing volatile gases or dust particles (coal mines, oil refineries, and chemical processing facilities).
T, TD, TK, and TDMK synchronous series provide power factor correction capabilities and operate at constant speeds regardless of load shifts.
YVFE3, YVFE4, and YVFE5 variable frequency and variable speed low/high voltage motors support high dynamic performance and precise speed regulation.
Z2, Z4, and Z series DC motors provide high torque output across a wide speed range, making them suitable for extrusion, metal rolling, and mining hoist systems.
Simo's motors are engineered for demanding applications across various climates and industries worldwide, from sub-zero mines in Siberia to high-humidity offshore platforms off Latin America.
Powering heavy mill grinding stations, stone crushers, underground conveyors, and blast furnace blowers. Standardized against abrasive dust and high vibration load profiles.
Providing explosion-proof low and high voltage motors for refineries, long-distance pipelines, raw gas extraction pumps, and hazardous petrochemical storage facilities.
Supplying massive synchronous and asynchronous motors to urban drainage pumps, large-scale irrigation canals, sewage treatment blowers, and water supply stations.
To ensure global compliance, SIMO Motor maintains an extensive range of international product and quality management system certifications. This guarantees alignment with environmental and safety regulations in global territories.

For procurement officers and industrial plant managers, selecting an OEM supplier goes beyond unit pricing. Consider these critical criteria to secure reliable, long-term performance:
Ensure your factory partner can match exact mechanical interfaces, custom shaft extensions, cooling methods (IC411, IC611, or IC81W), and protection classes (IP54, IP55, IP65). Custom mounting footprints minimize retrofitting costs during plant upgrades.
If utilizing VFDs for speed control, verify that the motor contains insulated bearings (to prevent electrical pitting from circulating shaft currents) and is equipped with forced ventilation to prevent overheating at low speeds.
For oil & gas or coal mining setups, verify that the flameproof paths (gaps and lengths) strictly comply with ATEX/IECEx standards. SIMO’s YBX series features high flameproof reliability with rigorous enclosure pressure testing.
Coordinate logistics to support the delivery of heavy high-voltage motors (often weighing several tons). SIMO provides export-ready sea freight packaging, customs clearance assistance, and full testing documentation.
