Explore our certified solutions engineered for global specifications. High-efficiency, safety, and durability integrated into every frame size.
Understanding the strict parameters governing electric motors deployed in volatile atmospheres.
In modern industrial processing plants, safety is the cornerstone of operational continuity. The presence of flammable gases, vapors, liquids, and combustible dusts creates complex hazardous environments where a single electrical spark, arc, or high surface temperature from an electric motor can result in catastrophic damage. This is where OEM Explosion Protection Motors play a vital safety-critical role. Engineered with robust cast-iron frames, reinforced terminal boxes, and advanced cooling pathways, these motors prevent ignition inside the motor casing from escaping into the surrounding environment, or keep internal surface temperatures safely below the auto-ignition thresholds of target explosive substances.
As a global OEM provider, our explosion-protection motors strictly comply with international flameproof frameworks, including ATEX, IECEx, UL, and GOST. From chemical processing facilities to offshore drilling rigs and deep shaft coal mines, industrial processes depend on electrical drive systems that deliver high efficiency (IE3, IE4, and IE5 standards) without compromising on safety margins. By leveraging state-of-the-art materials like dynamic stator core laminations and vacuum pressure impregnated insulation, our motors achieve thermal resilience that easily supports continuous (S1) operation under variable load conditions.
Xi’an Lite SIMO Motor Co., Ltd is a premier electrical engineering enterprise specializing in the manufacturing of large/medium-sized, high/low voltage AC motors, DC motors, synchronous motors, and explosion-proof motors within the Chinese mechanical industry. SIMO is a comprehensive manufacturing and service supplier of motor design, manufacturing, mechanical processing, mold making, and precision assembly.
Our company ranks among the top tiers in China’s motor manufacturing industry regarding the scale of production and technical deployment, maintaining a fast-growing development trend for consecutive decades. With more than 60 years of dedicated research and manufacturing excellence, our products have served critical infrastructure globally.
A timeline of innovation, growth, and industrial leadership since 1955.
The Company was founded in 1955 originally and now has more than 60 years history of motor manufacturing and selling. The registered capital is 21.5 million RMB. SIMO has 3 manufacturing factories, one subsidiary factory, with fixed assets 380 million RMB and more than 1172 sets of advanced equipment. There are more than 1200 employees, more than 260 technical engineers, including 21 senior engineers, and 15 expert engineers.
Analyzing the strategic and technical advantages of sourcing high-power industrial Ex motors from China.
Our facility maintains casting, stamping, coil winding, machining, and full test beds under one roof, slashing lead times and assuring component traceability.
Combining international testing certificates (ATEX, IECEx, UL) with Chinese industrial capacity allows us to offer world-class reliability at optimized costs.
Our 260 technical engineers customize shaft dimensions, mounting brackets, variable frequency drives (VFD), and specific terminal layouts for legacy plant retrofits.
Localized steel procurement and energy-efficient automation equipment minimize waste, translating into competitive pricing for high-volume OEMs.
Empowering global infrastructure through specialized mechanical engineering.
SIMO’s extensive research and development framework encompasses products spanning 34 major series, more than 1,800 varieties, and more than 19,500 specifications. Our electric motor power range spans from 0.35kW to 25,000 kW. This enables us to configure bespoke drive solutions for diverse applications:
For zones handling volatile hydrocarbons, our YBX3, YBX4, and YBX5 Series explosion-proof motors prevent gas ignition. These are commonly paired with heavy-duty pump drives and chemical transfer compressors.
Deep mining requires heavy start torque and dust protection. Our TDMK Series AC three-phase synchronous motors are engineered specifically for mine milling operations where constant speeds under high loads are mandatory.
High-voltage asynchronous induction motors like the YXKK, YXKS, and YKS series drive continuous industrial fans and high-volume water supply pumps with extreme thermal efficiency.
Additionally, for speed control and high starting inertia demands, our variable frequency drive motors (YVFE3, YVFE4, and YVFE5 series) allow precise frequency regulation. Wound rotor induction motors (YR, YRKK, and YRKS series) provide dynamic external resistance matching, and classical DC motors (Z2, Z4, and Z series) deliver robust torque profiles for metallurgical cranes, railways, and marine propulsion systems.
Proof of our rigorous testing, engineering integrity, and international conformity standards.
We pride ourselves on meeting global expectations. SIMO has successfully passed ISO9001 Quality System Certification, European Union "CE" safety standards, United States "UL" underwriters testing, Russian "GOST" parameters, and more. Our electric motors are widely applied in electricity, coal, petroleum, mining, metallurgy, railway, transportation, chemical industry, agriculture, water economy, aviation, navigation, and high technologies around the globe.
Aligning modern energy-saving policies with plant operations to future-proof your electric drive investments.
Global environmental directives like the EU ecodesign regulations have forced a massive shift toward energy-efficient designs. Industrial operations account for roughly 70% of total electrical energy consumption, with electric motor drives taking the majority share. Purchasing premium efficiency motors such as the YE4 and YE5 series lowers greenhouse gas emissions and delivers a rapid return on investment via power bill reductions. The thermal profile of a more efficient motor is also inherently cooler, extending the lifespan of insulation windings in hazardous settings.
Traditional fixed-speed motors often waste energy through fluid throttling in pump and fan systems. Utilizing variable frequency drive motors (VFD) like our YBBP Low Voltage Variable Frequency Explosion-Proof series allows flow control by modulating stator frequency. However, operating motors with high dv/dt VFD voltage spikes requires specialized stator insulation and insulated shaft bearings to prevent electrical discharge machining (EDM) current damage, an aspect our engineering team takes into consideration for all OEM builds.
Modern explosion-proof motors are increasingly outfitted with smart sensors to track real-time casing temperature, frame vibration, and current harmonics. This data is fed to cloud analytics engines for predictive maintenance, allowing plants to schedule bearing replacements before a critical failure triggers a downtime event. Our custom designs accommodate additional sensor housings within the explosion-proof envelope without compromising safety certifications.
