Engineered for high performance, maximum safety, and strict compliance with global industrial efficiency regulations.
Founded in 1955, Xi’an Lite SIMO Motor Co., Ltd stands as a premier comprehensive manufacturing enterprise in China's mechanical industry. We specialize in the design, development, mechanical processing, mold fabrication, assembly, and service of large, medium, and small high-voltage and low-voltage AC/DC electric motors, synchronous motors, generators, and heavy-duty explosion-proof motors.
Over the decades, SIMO has scaled up production capabilities to secure its rank among the absolute TOP enterprises in China's electric motor industry. By integrating advanced European design philosophies with highly reliable manufacturing procedures, we deliver exceptional energy efficiency and operational stability to heavy industrial processes worldwide.
Our journey traces back to the dawn of industrialization in China, expanding over 60 years from a municipal state-owned workshop to a leading global supplier of heavy electrical machinery.
Today, our equipment operates in critical applications across petrochemical refineries, massive mine milling systems, municipal water management projects, coal extraction sites, and steel processing plants globally.
Strategic engineering developments designed to meet carbon neutrality targets and the next generation of industrial automation.
By optimizing rotor geometry and employing premium electromagnetic silicon steels, our YE5 and asynchronous series achieve ultra-premium efficiency levels that drastically reduce operational carbon footprint and lifetime electricity expenses for plant owners.
Through our dedicated VVVF (Variable Voltage Variable Frequency) design schemes, including the YVFE3 and YJP series, we minimize harmonic heating losses and eliminate bearing currents using insulated bearings, facilitating seamless smart system integration.
Our ongoing R&D in hazardous environments has developed the YBX3, YBX4, and YBX5 explosion-proof induction motors. Designed for Zone 1, Zone 2, and dust environments (Zone 21/22), they feature flameproof enclosures that prevent internal explosions from igniting ambient atmospheres.
Matching critical heavy equipment demands with high-durability power systems.
SIMO's vast portfolio supports heavy machinery operations under severe environmental conditions, including thermal extremes, corrosive chemical exposure, high moisture levels, and heavy dust environments.
Our manufacturing base operates over 1,172 sets of specialized production machinery. Vertical integration allows SIMO to manage raw material selection, CNC mechanical processing, stator winding, rotor dynamic balancing, Vacuum Pressure Impregnation (VPI), and extensive load testing under one roof.
By using premium domestic supply chains for high-grade silicon steel sheet laminations and high-purity oxygen-free copper, we maintain excellent cost efficiency and supply chain resilience. This structural advantage ensures we meet project delivery dates even during market disruptions.
Our quality control engineers run electrical, thermodynamic, vibration, and noise measurements at our certified testing station, ensuring every motor leaving our bay conforms to actual design parameters.
Enabling multinational EPC contractors and industrial end-users to source exact-match machinery.
Tailoring stator winding configurations to support diverse grid voltages (380V, 415V, 660V, 3kV, 6kV, 10kV, 11kV) and dual frequencies (50Hz/60Hz). Custom isolation transformers and harmonic filter matching are available for VFD installations.
Offering customized shaft materials (such as high-grade forged steels), non-standard shaft dimensions, specialized mounting arrangements (flange, horizontal, vertical foot mounts), and split-sleeve bearings to match retrofitted legacy frames.
Equipped with Pt100 RTD resistance temperature detectors for bearings and windings, anti-condensation space heaters, oil level gauges, and vibration sensors, allowing integration into automated distributed control systems (DCS).
Certifications verifying compliance of our manufacturing facilities and products with international standards.
SIMO Motor operates a quality management system certified to ISO 9001 standards. Our product lines carry major regional and international safety and environmental certifications, including the European Union "CE" mark, United States "UL" standards, and Eurasian "GOST" specifications.
By complying with IEC 60034 and NEMA standard dimensions, our motors serve as reliable drop-in replacements for standard equipment designs during global overhaul projects.
Expert clarifications regarding electric motor selection, engineering requirements, and operational maintenance.
YKS (water-to-air cooled) motors offer compact sizes and lower noise levels, making them suitable for indoor setups with centralized cooling systems. YKK (air-to-air cooled) motors are self-contained and require no piping, making them ideal for outdoor environments or remote sites, though they have larger physical footprints.
VFDs can cause high-frequency voltage spikes (dv/dt stress) that degrade standard winding insulation. SIMO uses Class F insulation with Class B temperature limits, incorporating vacuum pressure impregnation (VPI) and corona-resistant magnet wire to protect windings from premature dielectric breakdown.
Our YBX3, YBX4, and YBX5 explosion-proof motors are designed and tested according to IEC 60079-0 and IEC 60079-1 standards. They feature robust enclosures that contain internal explosions without igniting gases (like methane, ethylene, or hydrogen) present in Zone 1 or Zone 2 locations.
IE5 motors reduce electrical losses by approximately 20-30% compared to IE3 units. For a 250kW motor operating continuously, this difference can save thousands of kilowatt-hours annually, resulting in a lower total cost of ownership over its operating life.
Engineered for high power demands, mining applications, and severe-duty factory tasks.
