Explore our elite selection of high-efficiency asynchronous, synchronous, explosion-proof, and variable frequency motors with optimized cooling designs.
For high-voltage (HV) and large-scale industrial motors, thermal dissipation is the core parameter dictating operating life, efficiency, and reliability. When high current flows through stator windings and rotor bars, copper and iron losses generate massive internal heat. Without highly responsive heat exchangers—traditionally designated as Motor AC Coolers—the temperature rises rapidly, leading to accelerated degradation of Class F/H insulation and stator coil insulation breakdowns.
As a leading Chinese motor manufacturer and cooling system specialist, Xi’an Lite Simo Motor integrates thermal engineering directly into motor structural dynamics. The configuration of air-to-air coolers (standardized as IC611) and air-to-water coolers (IC81W) are developed to maximize heat exchange coefficients while maintaining completely enclosed IP54 or IP55 enclosures. This ensures your motor stays protected from external contaminants like coal dust, moisture, and corrosive vapors.
| Cooling Code (IEC) | Method of Cooling | Core Application Environments | Primary Thermal Efficiency |
|---|---|---|---|
| IC01 | Open self-ventilation (air flow generated by internal fan) | Indoor, dust-free dry environments | Moderate |
| IC611 | Totally Enclosed Air-to-Air heat exchanger (top-mounted tube cooler) | Heavy dust, metallurgy, mining, outdoor yards | High efficiency via ambient air circulation |
| IC81W | Totally Enclosed Air-to-Water heat exchanger (tube-and-plate cooler) | Extremely high ambient temperatures, limited physical space | Ultra-high thermal extraction coefficient |
From our foundation in 1955 to a global force in motor manufacturing and integrated cooling technologies.
Xi’an Lite SIMO Motor Co., Ltd. is a pillar enterprise in the Chinese mechanical industry, specializing in the engineering, design, manufacturing, assembly, and service of large and medium-sized, high and low voltage AC/DC motors, synchronous motors, and explosion-proof motors. Over the course of more than six decades, SIMO has grown to rank at the absolute top of China's motor manufacturing sector.
Our operation is completely comprehensive, encompassing specialized R&D divisions, mechanical tooling processing centers, mold fabrication shops, sophisticated coil-winding stations, vacuum pressure impregnation (VPI) insulation lines, and national-grade product testing centers. The scale of our production allows us to dynamically support global machinery distributors, EPC project contractors, and large industrial end-users with robust motor systems designed for prolonged industrial lifespans.
A timeline showing our path to becoming China's leading heavy industrial motor manufacturer and exporter.
SIMO Motor established and led by the state government to support early industrial development.
Relocated to a newly constructed manufacturing plant in the historic industrial city of Xi'an.
Renamed to Xi'an Motor Factory after acquiring and integrating several regional motor components suppliers.
Reformed into a highly responsive limited company from a state-owned factory to improve efficiency.
Establishment of SIMO Motor Group, managing 14 specialized subsidiaries across China.
Relocated to a state-of-the-art manufacturing campus designed for Industry 4.0 automation.
Transitioned brand name to Tech Full Simo Motor, reinforcing a global technology-first strategy.
Continuing to innovate high-voltage, energy-efficient IE4/IE5 motors with smart cooling integrations.
How our integrated factory ecosystem delivers rapid production, unmatched precision, and global logistics reliability.
By using automated punching machines and high-accuracy laser cutters, stator and rotor laminations are produced with minimal iron loss. Standardized heat exchangers and cooling tubes are fabricated on site to ensure perfect structural tolerances.
Our heavy-duty vacuum pressure impregnation (VPI) systems completely eliminate air pockets in windings. Employing Class H solventless resins ensures superior thermal conductivity, moisture-proofing, and mechanical strength against vibration.
Every rotor, together with its cooling fan assembly, undergoes two-plane dynamic balance refinement. This keeps residual imbalances well below ISO G1.0/G2.5 levels, minimizing noise and shaft wear during startup.
Our registered capital is 21.5 million RMB, supporting 3 specialized motor manufacturing factories and 1 subsidiary company. Our fixed assets total over 380 million RMB, featuring more than 1,172 sets of advanced industrial machinery. The current capacity ranges from low voltage 0.35 kW up to high voltage 25,000 kW, across 34 major series, 1,800 varieties, and over 19,500 custom specification options.
Direct integration of heavy-duty industrial electric motors and high-capacity AC coolers to solve critical cooling issues in harsh working conditions.
Standard electric motors often fail when exposed to high-dust and extreme ambient temperature environments. SIMO Motor overcomes this limitation by pairing robust, heavy-duty frames with specialized cooling units:
Exploring next-generation technologies designed to maximize motor operating lifespans and energy savings.
Modern electric systems require active cooling control. Running a cooling fan at maximum speed when a motor is idling wastes substantial energy. SIMO’s technology roadmap integrates smart variable frequency drives (VFDs) and thermal sensors directly into our motor cooling systems:
By utilizing embedded PT100 temperature detectors inside the stator slots and bearings, real-time temperature data is processed by our intelligent control system. When combined with VVVF variable speed technology, the cooling fan’s speed adjusts dynamically to the motor's actual thermal load. This reduces auxiliary energy consumption by up to 40% while preventing thermal shock in the windings.
We are also developing digital twin models for our industrial heat exchangers. Integrated vibration and pressure sensors in the air-to-water cooling tubes detect internal scaling or flow obstructions, alerting maintenance crews before issues escalate.
Rigorous verification ensures seamless performance and simplified regulatory approval in all international markets.
Simo Motor has successfully implemented and passed the ISO9001 Quality System Certification, the European Union's "CE" certification, the United States' "UL" safety standards, and the Russian "GOST" certification. Our manufacturing standards strictly adhere to IEC standards, ensuring plug-and-play compatibility and compliance on industrial projects worldwide.
