Global Industrial Powertrain Solutions: High-Voltage, Heavy-Duty Induction & Synchronous Motors Engineered for Optimal Operational Lifecycle TCO.
Direct procurement of premium three-phase asynchronous, synchronous, flameproof, and high-efficiency induction motors customized to standard IEC/NEMA configurations.
LITESIMO is an industry-leading enterprise specializing in the engineering, design, and manufacture of large and medium-sized, high/low voltage AC motors, DC motors, synchronous motors, and explosion-proof motors within the Chinese mechanical industry.
As a comprehensive manufacturing and service supplier, SIMO integrates motor design, advanced mechanical processing, mold making, and precision assembly. Our scale of production ranks at the very top of China’s motor sector, establishing LITESIMO as a key player in global industrial motor supply. We maintain a sustained growth rate driven by high-tech equipment and deep engineering expertise.
Established in 1955 under state oversight, SIMO has spent over 60 years refining the design and fabrication of rotating electrical machinery. The history below details our transition from a state-owned plant to a premier international motor supplier.
LITESIMO's engineering and research infrastructure covers the entire lifecycle of industrial electric motor production. Our catalog contains 34 major series, over 1,800 varieties, and more than 19,500 individual specifications.
The power output span ranges from 0.35 kW to 25,000 kW. Our principal motor designs include:
Procuring medium voltage (MV) and high voltage (HV) electric motors requires balancing initial capital expenditure (CAPEX) with long-term operational costs (OPEX).
Our medium voltage winding design uses a Vacuum Pressure Impregnation (VPI) process with Class F/H epoxy resins, eliminating air pockets to ensure high dielectric strength and resistance to moisture and chemical attack.
Raw material sourcing (cold-rolled silicon steel laminations and high-purity electrolytic copper) combined with centralized manufacturing in Xi'an allows SIMO to supply reliable products without quality compromise.
We manufacture systems aligned with key safety standards, including explosion-proof configurations certified under ATEX, IECEx, and China’s national Ex standard, ensuring safe operation in hazardous atmospheres.
For industrial engineering procurement, the purchase price of an electric motor represents only a fraction of its lifetime cost. Energy consumption typically accounts for over 90% of a motor's TCO. Selecting a high-efficiency model (such as our YE4 or YE5 series) reduces energy loss. Our electrical designs minimize stray load losses, rotor I2R losses, and windage friction, which helps lower operating expenses in continuous-duty applications like water utilities, mine ventilation, and petrochemical refinement.
Operating temperature directly influences insulation life. A 10°C increase in operating temperature above the insulation limit halves insulation lifespan. SIMO designs feature optimized cooling geometry: TEFC (Totally Enclosed Fan Cooled, IC411), TEAAC (Totally Enclosed Air-to-Air Cooled, IC611), and WPII (Weather Protected Type II). These configurations maintain stable internal temperatures even under variable loads or high ambient conditions.
SIMO has established and maintains a certified quality management system. Our designs comply with ISO9001, EU "CE", US "UL", and Russian "GOST" requirements, allowing our motors to integrate with global power grids.
















LITESIMO employs advanced machining, computer-controlled winding machine suites, and high-capacity testing bays to verify mechanical balance, vibration signatures, and dielectric performance before shipment.
