Explore our leading industrial electric motors, designed for high voltage efficiency and hazardous duty safety.
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, and assembling. The Company ranks TOP in China’s motor industry as to its scale of production, and has maintained a fast-growing development trend for consecutive years.
By integrating deep technical expertise with advanced mechanical capabilities, SIMO has set industry standards across heavy-duty mining, petrochemical processing, and infrastructure domains. Our specialized motors are engineered to operate continuously under extreme ambient conditions, where dust, volatile gas mixture, or immense load variations present major operational threats.
Over six decades of growth, evolution, and innovation in the heavy electric machinery industry.
SIMO's R&D cover all types of motors, with products across 34 major series, 1,800 varieties, and over 19,500 specifications, spanning power outputs from 0.35kW to 25,000 kW.
Designed for severe-duty applications requiring continuous structural stability under large power demands.
Certified flameproof and dust explosion-proof models to isolate electrical ignition inside combustible environments.
Specialized drives offering power-factor correction and precision control for massive industrial equipment.
Developing next-generation electric drivetrains that push the limits of efficiency, thermal isolation, and diagnostic intelligence.
To reduce operational carbon footprints and electricity expenditures, SIMO is driving the transition of its explosion-proof and flameproof motor lines (YBX5 series) to meet and exceed IE5 efficiency limits. By incorporating low-loss electrical steel sheets and optimizing rotor topologies, we minimize copper losses, which subsequently lowers internal operating temperatures—a key safety advantage in gas-dense environments.
Future hazardous duty motors are not just mechanical components; they are interconnected sensor nodes. SIMO's roadmap integrates explosion-proof certified temperature, vibration, and magnetic flux sensors directly into the frame. These sensors relay real-time telemetry to edge-processors, allowing plant operators to deploy Prognostics and Health Management (PHM) techniques to foresee winding insulation failure or bearing wear before catastrophic downtime occurs.
High-voltage (6kV/10kV) machines operate under tremendous dielectric stress. SIMO's continuous innovation in vacuum pressure impregnation (VPI) with solventless epoxy resin ensures void-free winding encapsulation. We are currently researching nano-composite insulating materials to increase resistance to high dV/dt stresses caused by modern variable frequency drives (VFDs), mitigating partial discharge failures.
Custom-engineered drivetrains designed to resolve critical engineering bottlenecks in heavy production sectors worldwide.
In refineries and processing plants where hydrocarbons create volatile atmospheres, the risk of electrical arcs causing disastrous explosions is constant. SIMO's YBX3 and YBX4 flameproof motors are engineered with heavy cast-iron enclosures, labyrinth shaft seals, and flame-retardant terminal boxes, certified to block internal ignition paths and safely contain combustion pressures.
Mining operations require uninterrupted high torque under heavy dust concentration and voltage drops. Our customized TDMK synchronous motors are tailored for large mine grinding mills, offering power factor correction that saves energy across the entire facility network. Concurrently, YBK3 underground coal mine motors offer high structural durability to withstand impacts and highly corrosive ambient humidity.
Continuous steel casting and rolling mills demand high-torque DC motors (Z2, Z4, Z series) capable of rapid speed adjustments under sudden peak overloads. SIMO’s DC series utilize advanced armature winding patterns and optimized commutator segments to guarantee excellent commutation characteristics, minimizing sparking and downtime in environments of high heat and metal slag.
Operating from a state-of-the-art facility in Xi’an, China, SIMO Motor implements a highly integrated Smart Factory 4.0 model. By utilizing robotic winding machinery, computerized balancing rigs, and automated vertical VPI installations, we guarantee consistent build tolerances across large-batch runs. Vertical integration is our key cost advantage; we maintain in-house mold making, steel stamping, machining, and full-load testing bays.
This vertical integration ensures our supply chain remains resilient against external raw material disruptions. For global procurement officers, this means predictable lead times, reduced shipping delays, and significant cost savings relative to regional European or North American manufacturers, without compromising on materials or component sourcing.
SIMO passed ISO9001 Quality System Certification, EU "CE", US "UL", Russian "GOST", and so on. Electric motors are widely applied in electricity, coal, petroleum, mining, metallurgy, railway, transportation, chemical industry, agriculture, water economy, aviation, navigation, and high technologies.
Fully compliant with low-voltage and electromagnetic compatibility (EMC) regulations, meeting rigorous European environmental and safety directives for industrial machinery.
Designed and structured in compliance with UL standard directives for electric motors, ensuring safety and thermal performance levels accepted across North American industrial grids.
Fully certified under the Technical Regulations of the Customs Union, ensuring reliable sub-zero operation and heavy-duty compliance required by Russian and Eurasian mines and refineries.
Deploying heavy industrial machinery requires localized technical assistance, compliance alignment, and rapid spare parts logistics.
Different regions follow distinct mounting configurations (IEC vs NEMA). SIMO provides fully custom structural adaptions, including special shaft extensions, non-standard keyway configurations, and unique D-flange/C-face mountings, ensuring seamless retrofitting without modifications to existing machine frames.
Whether deploying to desert operations with temperatures reaching +55°C, or Arctic mining sites plunging to -50°C, SIMO engineers tailors structural alloys, winding insulations, and grease properties to sustain operating integrity. Class H insulation and specialized space heaters are integrated for high-humidity sites.
Navigating explosion-proof regulations can be highly complex. Our engineering department reviews the project site parameters—Zone 1, Zone 2, Group IIA, IIB, or IIC, and Temperature classes (T1-T6)—to supply units configured precisely to regional standards, preventing expensive field compliance rejections.
