In modern industrial landscapes, medium voltage (MV) motors act as the vital organs of municipal infrastructures, petrochemical refineries, chemical complexes, large-scale mining operations, and major utility plants. Procurement strategies have evolved beyond basic cost metrics, focusing heavily on life-cycle costs, operational redundancy, and direct energy footprint reductions.
Standardized off-the-shelf motors often fail to satisfy specific operational conditions, such as high-altitude derating, ambient temperatures exceeding 50°C, and custom shaft extensions. Global procurement groups require deep mechanical customized layouts to interface seamlessly with legacy pumps, compressors, and grind mills without expensive structural foundation rebuilds.
With global net-zero targets, industries are actively phasing out inefficient systems. Installing Ultra-Premium Efficiency classes (IE4 and IE5) like our YE4 and YE5 lines yields millions in savings over a motor's typical 25-year service life, making the electrical design stage critical for strategic procurement decisions.
Heavy mining, underground processing, and chemical refining call for robust, certified flameproof machinery. Compliance with international flameproof frameworks (e.g., ATEX, IECEx, UL, and GOST) ensures absolute reliability and crew safety in hazard-rich locations containing coal dust or volatile hydrocarbon compounds.
Xi’an Lite SIMO Motor Co., Ltd stands as a primary enterprise specializing in the design, engineering, and manufacturing of large/medium-sized, high/low voltage AC motors, DC motors, synchronous motors, and explosion-proof motors within the global mechanical industry. Over the course of six decades, SIMO has grown into a comprehensive manufacturing and service supplier capable of handling custom motor design, advanced precision machining, complex mold making, electrical assembly, and systematic quality validation.
Currently ranking at the top tier of China's motor manufacturing sector regarding production scale, SIMO maintains a steady trajectory of scientific innovation, technical leadership, and global business expansions.
SIMO Motor was established under state guidance, establishing a core foundation for industrial motor manufacturing in China.
Relocated to a newly constructed manufacturing plant in the historic industrial city of Xi'an.
Renamed to Xi'an Motor Factory following strategic national acquisitions and industrial consolidation.
Reformed from a state-owned enterprise into a modern limited liability company, accelerating market competitiveness.
SIMO Motor Group established, growing to incorporate 14 specialized subsidiaries.
Transitioned operations to a state-of-the-art, high-tech industrial manufacturing facility.
Formally structured as Tech Full Simo Motor, optimizing global supply chains.
Continually driving innovation as a premier global motor supplier with modern digital manufacturing frameworks.
Equipped with over 1,172 sets of advanced manufacturing and testing equipment, our factories possess the capability to engineer high-voltage, low-voltage, AC, DC, and synchronous machinery. We implement Vacuum Pressure Impregnation (VPI) for insulation systems and utilize dynamic balancing equipment to secure operational stability across all speed ranges.
Our manufacturing R&D covers 34 major series, more than 1,800 varieties, and over 19,500 distinct specifications, scaling from 0.35 kW up to 25,000 kW. Our key motor series include:
Each industry brings distinct operational challenges. Below is how our custom medium voltage motor topologies align with specific engineering and environmental requirements.
Mining operations require extremely high starting torque under heavy loads. The TDMK series synchronous motors are designed specifically for ball mills and SAG mills in mining environments. They operate at high efficiency while assisting in plant power factor correction, reducing utility penalty costs.
Volatile gases demand robust containment structures. Our YBX3, YBX4, and YBX5 explosion-proof lines feature flameproof enclosures designed to contain internal explosions without propagating them to the external environment, adhering to international ATEX/IECEx specifications.
Municipal water pumps require continuous duty (S1) reliability. The YKS and YKK high-voltage induction series feature advanced air-water (YXKS) or air-air (YXKK) cooling systems, ensuring stable thermal performance during extended, continuous operation.
Driven by industrial digitalization and carbon reduction targets, our engineering department focuses on three primary technical pillars:
Moving past conventional IE3/IE4 designs, our YE5 and YVFE5 lines utilize optimized electromagnetic designs and low-loss silicon steel sheets to reduce stator and rotor losses, meeting the highest global efficiency regulations.
Integration of RTD temperature sensors (Pt100) inside stator windings and bearing housings, alongside vibration sensors, allows for real-time monitoring and predictive maintenance, reducing unplanned downtime.
For VFD-driven systems, SIMO uses reinforced phase-to-phase and turn-to-turn insulation alongside insulated bearings. This prevents damage from high dV/dt voltage spikes and high-frequency circulating shaft currents.
To serve international markets, our products conform to key global standards, including ISO9001, European CE, American UL, and Russian GOST frameworks. This enables seamless deployment across diverse regions.
