Explore our flagship industrial motor lineup engineered for extreme conditions, ultra-high efficiency, and unmatched operational reliability.
Xi’an Lite SIMO Motor Co., Ltd is a premier, pioneering enterprise in the Chinese mechanical industry, specializing in the manufacturing of large and medium-sized, high and low voltage AC motors, DC motors, synchronous motors, and explosion-proof motors.
SIMO stands as a comprehensive engineering and manufacturing giant, integrating motor R&D, mechanical processing, precision mold manufacturing, state-of-the-art assembly, and global technical services. The company consistently ranks top in China’s electric motor industry in terms of production scale, technical advancement, and export volume, sustaining a rapid growth trajectory for consecutive decades.
How SIMO custom-engineered motor systems optimize safety, throughput, and energy conservation across critical oil, gas, chemical, and mining applications.
Oil pump motors require extreme resilience to torque fluctuations. Our large synchronous and high-voltage induction motors drive pipeline pumps, gas compressors, and oil transport networks globally, ensuring zero unexpected downtime in critical supply lines.
Petrochemical facilities require stringent explosion protection. Our line of explosion-proof motors (YBX3, YBX4, YBX5) is built to conform to global ATEX and IECEx standards, safeguarding operations against flammable gases, vapors, and combustible dusts.
From deep-well coal mine ventilation to agricultural water systems, our heavy-duty wound rotor motors (YR, YRKK) and high-efficiency induction systems deliver high starting torque and thermal durability in the most abusive environments.
Engineered for extreme environments, covering a power range from 0.35kW up to 25,000 kW. Our dynamic production capacity includes 34 major series, over 1,800 varieties, and 19,500 custom specifications.
Our core R&D portfolio includes high-efficiency systems optimized for modern variable frequency drives (VFDs) and high-voltage grid topologies:
Established in 1955, our journey is marked by technical breakthroughs, state ownership transition, and continuous technological expansion.
SIMO Motor was established and led by the Chinese government, setting the foundation for heavy-duty industrial electric motor manufacturing in Northwestern China.
Relocated to a newly constructed manufacturing facility in Xi'an city, expanding engineering capabilities and machinery footprint.
Changed official designation to Xi'an Motor Factory following strategic government-led acquisitions and industrial integration.
Successfully reformed from a state-owned factory into a modern limited liability company, introducing agile corporate structure and global sales networks.
SIMO Motor Group established, organizing 14 specialized subsidiary factories to optimize design, casting, winding, testing, and service pipelines.
Moved operation to our modern, high-tech development zone plant, adopting advanced CNC manufacturing and environmental testing labs.
Formally restructured and rebranded to Tech Full Simo Motor, aligning corporate focus with high-voltage and high-efficiency motor R&D.
Strengthening our position as one of the world's most trusted industrial motor suppliers, actively exporting to over 40 countries across Europe, the Americas, and Asia.
Our commitment to absolute reliability is backed by rigorous testing systems and compliance with international standards including ISO9001, European CE, American UL, and Russian GOST.
SIMO motors undergo complete stator core testing, dynamic balancing, insulation dielectric testing, and load-simulate testing. Our internal labs ensure that each high-voltage motor shipped possesses structural integrity, minimal noise characteristics, and long-term bearing reliability under continuous heavy industrial operations.
Our R&D team is actively shaping the future of industrial motion by incorporating intelligence, sustainable efficiency, and material innovation.
Integrating real-time temperature, vibration, and acoustic sensors inside our high-voltage stator casings. Our upcoming smart-motor setups connect to cloud diagnostics to alert engineers of bearing wear prior to fault events.
Building on the current success of our IE5 three-phase synchronous and asynchronous systems, SIMO's engineering department is testing rare-earth PM materials and optimized rotor slot configurations to approach IE6 efficiency limits.
Developing advanced synthetic polymers for Class H and higher vacuum pressure impregnation (VPI) systems, designed to sustain oil pump motor operations at ambient temperatures up to 60°C or arctic lows down to -45°C.
