Direct from Xi'an Lite Simo Motor's state-of-the-art manufacturing facilities. Engineered for high performance, efficiency, and reliability under extreme operating conditions.
Xi’an Lite SIMO Motor Co., Ltd is an electric company, main enterprise specializing in the manufacturing of large/medium-sized, high/low voltage AC motors, DC motors, synchronous motor, and explosion-proof motor in the Chinese mechanical industry. SIMO is a comprehensive manufacturing and service supplier of motor design, manufacturing, mechanical processing, mold making, assembling. The Company ranks TOP in China’s motor industry as to its scale of production, and has maintained fast-growing development trend for consecutive years.
By focusing on semantic search alignment and understanding exact industrial buyer intents, SIMO has engineered heavy machinery drive solutions that resolve structural and operational stress points. Our motors perform under demanding electrical gradients and environmental parameters, offering deep customization capabilities that enable precise matching with international system integrators.
We integrate thermal efficiency matching, finite element rotor structural design, and advanced vacuum pressure impregnation (VPI) insulation techniques. This ensures that every high/low voltage motor shipped provides the necessary mechanical torque output, thermal limits, and durability.
Our origins as a state-owned industrial enterprise have shaped our engineering discipline. Sixty-eight years of experience form the foundation of our capability to supply heavy-duty high-voltage motors that meet rigorous global standards.
The registered capital is 21.5 million RMB. SIMO operates 3 primary manufacturing plants and 1 subsidiary facility. Our operations are supported by fixed assets totaling 380 million RMB and more than 1,172 sets of advanced industrial production equipment.
Our production capabilities are sustained by a workforce of over 1,200 employees, including more than 260 technical engineers, 21 senior engineers, and 15 dedicated industrial experts.
YX, YXKK, YXKS series high-voltage high-efficiency motors; YR, YRKK, YRKS wound rotor slip-ring motors; YE3, YE4, YE5 super high-efficiency low-voltage asynchronous motors; YVFE3, YVFE4, YVFE5 variable frequency speed regulating systems; explosion-proof Ex motors (YBX3, YBX4, YBX5); T, TD, TK, TDMK synchronous motors; TFW large synchronous generators; and Z2, Z4, and Z heavy DC motors.




Aligning motor parameters with operational environments. SIMO designs systems tailored to specific industrial sectors, ensuring long-term reliability and performance.
Designed to withstand dust, moisture, and high starting loads. Our TDMK synchronous motors and wound rotor YRKK series provide the starting torque required for ball mills, crushers, and heavy conveyors.
Our Z4 and Z series DC motors provide the speed-torque control required for steel rolling mills, scrap shredders, and heavy-duty wire drawings, operating reliably under cyclic thermal loads.
YBX3, YBX4, and YBX5 explosion-proof motors are designed to operate safely in zone-classified environments (coal mines, oil refineries, and gas transport systems), meeting international flameproof standards.
Highly efficient YXKS water-cooled high-voltage motors and YKK air-cooled induction motors provide continuous service for metropolitan water supply networks, flood control, and agricultural drainage systems.
How Litesimo optimizes lead times and secures material supply chains for large-scale international motor projects.
Modern electric motor manufacturing requires strict material specification control. SIMO employs raw material quality tracing for copper wire purity, non-oriented silicon steel magnetic loss properties, and structural forging integrity. Our factories in Xi’an use computerized CNC machining centers, automated high-speed punching presses, and digital wire winding systems to reduce process variations.
Our assembly line integrates advanced vacuum pressure impregnation (VPI) equipment. VPI coats the stator windings with Class H or Class F insulation resins, removing micro-voids to improve moisture resistance and thermal conductivity.
SIMO features an integrated testing center capable of full-load load testing on high-voltage AC and DC motors. Every unit undergoes vibration testing, partial discharge analysis, and winding resistance verification prior to packaging.
In international procurement, logistics predictability is critical. SIMO coordinates with domestic raw material suppliers and international shipping networks to maintain production schedules.
Pioneering the shift toward ultra-efficiency and digital motor operations to support global decarbonization goals.
We are expanding our product line to transition from IE3/IE4 asynchronous systems to IE5-compliant ultra-high efficiency induction and Permanent Magnet Synchronous Motors (PMSM). This development reduces operational energy consumption by up to 8% compared to standard configurations.
SIMO's upcoming motor generations feature options for integrated smart sensors. These modules monitor bearing temperature, vibration patterns, and winding heat outputs in real time, transmitting predictive maintenance data directly to control systems.
We are phasing in zero-VOC solvent-free impregnating resins across our VPI production lines. This process modification reduces carbon footprint during the curing cycle while maintaining high insulation performance under harsh conditions.
SIMO has implemented a quality management framework to meet international requirements. Our manufacturing facility is certified under ISO9001 and verified by globally recognized inspection standards.
Our systems meet the specific requirements of international certification bodies. The electric motors we design are certified under EU CE, US UL, Russian GOST, and other standards, ensuring compliance with global industrial safety and performance criteria.
Whether configured for high-altitude mines, petrochemical facilities, or maritime operations, our engineering department provides design support, dimensional drawing adjustments, and structural analysis.
SIMO electric motors are used in key sectors worldwide, including power generation, coal mining, petrochemicals, metallurgy, rail transit, water management, agricultural irrigation, and aerospace applications.
SIMO has passed ISO9001 Quality System Certification, EU "CE", US "UL", Russian "GOST", and more. View a selection of our quality management and international compliance certifications below:
















Essential electrical and mechanical metrics to specify when sourcing high/low voltage industrial electric motors from China.
Verify rated grid voltage (3kV, 6kV, 10kV, or custom low voltage) and supply frequency tolerance. Ensure proper integration with Variable Frequency Drives (VFD) by identifying harmonic filters and insulated bearing requirements.
Define IP ingress protection class (typically IP54 or IP55 for standard applications, higher for wet/mining environments). Specify explosion-proof markings (Ex d, Ex de, Ex e) for oil/gas sites.
Check terminal box positioning (top, left, or right-hand mount). Request certified shaft alignment dimensions, bearing temperature sensor specifications (Pt100 RTDs), and dynamic rotor balancing grades.
