Modern industrial markets face shifting demands driven by the dual pressures of regulatory compliance and operational optimization. In high-power sectors, electric motors are responsible for upwards of 70% of total electrical energy consumption. This reality has driven international regulatory frameworks (such as EU Ecodesign directives and US DOE mandates) to enforce transitions from legacy efficiency grades (IE1 and IE2) toward IE3 (Premium Efficiency), IE4 (Super Premium Efficiency), and IE5 (Ultra-Premium Efficiency) standards.
Simultaneously, heavy industries like petrochemical processing, deep-pit mining, and metropolitan water transmission require robust safety performance. The demand for explosion-proof certifications (such as ATEX, IECEx, and UL hazardous location listings) is growing rapidly due to stricter occupational safety laws worldwide. To succeed in this landscape, OEMs require a partner capable of executing precise modifications on high-power motors without compromising efficiency or safety ratings.
Our product lineup features 34 major series, over 1,800 varieties, and 19,500 distinct specifications, spanning a power range from 0.35kW to 25,000kW. Below, we break down the technological features of these key systems:
Engineered for high-power utility pumps, compressors, and ventilation systems. Feature compact housing geometries, vacuum pressure impregnated (VPI) insulation classes, and low starting currents. Available in both air-to-air (YXKK) and air-to-water (YXKS) cooling configurations to optimize thermal dissipation in enclosed settings.
These slip-ring systems are designed for high-inertia applications requiring high starting torque under load (such as heavy crushers, ball mills, and conveyor drives). The wound rotor construction allows connection of external resistance banks, minimizing grid disruption during start-up.
Designed with flameproof, dust-ignition-proof housings, making them suitable for hazardous environments containing volatile hydrocarbons or combustible dust. Built with non-sparking materials and certified to withstand internal explosions without venting flame to the exterior atmosphere.
Our YE5 series represents advanced asynchronous motor technology, complying with IE5 efficiency ratings. Using optimized stator slot geometries, high-fill copper windings, and high-performance silicon steel sheets, these motors reduce electromagnetic and rotor loss by up to 20% compared to standard motors.
Designed for large-scale industrial processes like reciprocating compressors and grinding mills. These motors offer adjustable power factor correction, helping plants optimize overall grid utilization and maintain stable operating speeds under varying load conditions.
Designed for applications requiring wide-range, smooth speed control and high transient overloads, such as metal rolling mills, extrusion machines, and mine hoists. These motors feature robust commutators and split-stator casings for simplified maintenance.
Operating from our modern manufacturing base in Xi'an, SIMO Motor maintains stable production through an integrated supply chain. We maintain long-term partnerships with leading domestic suppliers for essential materials, including high-permeability cold-rolled silicon steel and high-purity oxygen-free copper. By managing casting, machining, winding, VPI insulation treatment, and performance testing in-house, we reduce production bottlenecks and maintain consistent quality control across all stages.
Our facility houses over 1,172 sets of advanced manufacturing and testing equipment, including large-scale CNC machining centers, automated coil winding machines, precision balancing rigs, and comprehensive motor test bays. This deep capacity allows us to manage large production volumes while remaining flexible enough to customize mechanical structures for specific OEM requirements. The result is shorter lead times and more reliable delivery schedules for global industrial projects.

Because industrial environments vary, our motors are built with specialized configurations to handle distinct environmental hazards, electrical conditions, and mechanical loads:
For refining and gas compression sites, we supply explosion-proof motors (such as the YBX5 series) with Class I Division 1/2 or Zone 1/2 certifications. These motors feature spark-proof fans and corrosion-resistant coatings to prevent ignition in environments containing volatile organic compounds.
Underground and open-pit mining requires motors that can handle continuous dust exposure, severe vibrations, and high starting loads. Our YBK3 flameproof series and YRKK wound rotor motors are engineered with IP55 or IP56 enclosures and reinforced shafts to power conveyor belts, ball mills, and ventilation shafts reliably.
For municipal water distribution and treatment facilities, our high-voltage YKS air-to-water cooled motors drive high-capacity water pumps. These systems are designed for continuous, multi-year operation, helping municipal networks optimize water flow while keeping maintenance downtime to a minimum.
In thermal and hydro power generation, large industrial draft fans and feed pumps require continuous variable speed control. Our variable frequency AC motors (YVFE3/YVFE4 series) integrate with modern VFD drives, allowing plant operators to adapt speeds to changing load profiles and reduce auxiliary energy consumption.
As industrial automation and digitization progress, SIMO is updating its motor technologies to support smart industrial networks. Our R&D team is currently developing and deploying solutions across three key areas:
SIMO's quality management framework is verified by international compliance bodies, ensuring our motors meet local regulatory standards in your market.
Our engineering and production processes are certified to meet major international standards. SIMO maintains ISO9001 Quality System Certification, European Union "CE" safety compliance, United States "UL" electrical standards, and Russian "GOST" parameters. This compliance structure simplifies integration and site inspection processes for international engineering projects.
