Delivering high-efficiency electric motors to critical energy and production hubs worldwide.
Industrial motors represent the literal muscles of modern societies, consuming more than 45% of global electrical energy. In today's landscape of energy optimization and aggressive carbon reduction mandates (such as EU MEPS, US DOE regulations, and China's GB18613 standards), the switch to premium efficiency motors is not just an option—it is a regulatory and commercial necessity.
At SIMO Motor, our global reach addresses the exact demands of heavy-duty industries including petrochemical extraction, iron & steel metallurgy, coal processing, municipal water distribution, paper mills, and massive mining mills. With systems certified under globally accepted protocols (including EU CE, US UL, and Russian GOST), our high-voltage and flameproof lines are trusted from Siberian oilfields to South American copper operations. By optimizing raw copper layout designs, electromagnetic flux distributions, and mechanical heat dissipation, we offer clients up to 40% reduced energy overhead, which directly elevates long-term ROI.
Understanding the engineering behind our motors: YXKK, YRKK, YBX, and TDMK series.
Power Range: Up to 25,000 kW | Voltage Options: 3kV, 6kV, 10kV, 11kV
Designed with compact box structures, utilizing premium silicon steel sheets for minimal core losses. The wound rotor (YR/YRKK) variant delivers massive starting torque under heavy loads via external slip rings, perfect for compressors, fans, and shredders.
Ex-Proof Rating: Ex d I Mb, Ex d IIB T4 Gb, Ex tD A21 IP65
Specially built to isolate internal electric sparks or flames from flammable gases, coal dust, or chemical vapors. These motors are certified under tight hazardous area directives, utilizing flame-tight path enclosures and heavy-duty cast iron frames.
High Torque Density: Engineered for continuous mineral ball mills.
By integrating advanced excitation controllers, our TDMK motors operate at leading or lagging power factors, improving the power grid efficiency of the entire mine site while enduring heavy starting torque impulses.
The R&D and manufacturing divisions of SIMO Motor cover all essential industrial layouts. Our full spectrum covers 34 major series, comprising over 1,800 varieties and 19,500 individual specifications. Our power profiles scale from a modest 0.35 kW up to high-powered 25,000 kW units, satisfying both low-voltage standard machinery and giant high-voltage utility setups.

Successfully reformed from a state-owned enterprise into a modern, agile limited liability company.
Establishment of SIMO Motor Group, expanding manufacturing divisions across 14 specialized subsidiaries.
Relocated manufacturing center to a high-tech advanced industrial zone to expand production volume.
Renamed to Tech Full Simo Motor, aligning with new international commercial channels and quality frameworks.
Embraced industry 4.0 standards, smart diagnostic integrations, and ultra-high-efficiency motor designs.
Why buying directly from SIMO Xi'an guarantees superior pricing and production reliability.
Purchasing industrial motors from a direct Chinese manufacturer like SIMO Motor offers crucial operational benefits. First, our factory utilizes a deeply integrated local supply chain in Xi'an—one of China’s major mechanical manufacturing corridors. This localized grid secures raw materials like high-grade non-oriented silicon steel coils and 99.99% pure electrolytic copper wind wire with minimal lead times.
Furthermore, our facility houses over 1,172 sets of advanced equipment. This allows us to handle heavy processes—such as frame casting, shaft CNC turning, dynamic rotor balancing, and computer-controlled Vacuum Pressure Impregnation (VPI)—entirely in-house. By removing intermediaries, we offer highly competitive pricing without sacrificing build quality. Whether ordering custom units or standard models, our clients bypass additional broker markups and receive direct factory-warranted quality.
Real-world engineering challenges solved by SIMO premium electric motors.
In underground mining, coal dust and methane gas create highly explosive environments. The YBK3 and YBX3 flameproof motors are engineered with heavy explosion-proof enclosures. In the event of an internal electrical spark, the motor frame contains the combustion and prevents it from igniting the surrounding atmosphere, ensuring continuous operation for ventilation fans, shearers, and conveyor belts.
Cement manufacturing and mineral mills require massive starting torque and continuous operation under dusty conditions. Our custom TDMK AC synchronous motors deliver high torque density and help correct power factors. This combination ensures reliable grinding, helps mining plants reduce reactive power penalties, and stabilizes their power grid.
Pumps and compressors in refineries often handle volatile hydrocarbon gases. Using low-voltage and high-voltage YBBP explosion-proof variable frequency motors allows engineers to modulate pump flow rates with precise speed regulation. This setup maintains safe operations in Zone 1 and Zone 2 environments while optimizing energy consumption.
Developing next-generation smart, ultra-efficient power solutions.
Industrial motors are evolving toward smart diagnostic integration and ultra-high efficiency. SIMO Motor's technical roadmap focuses on three main developments:
