Explore our engineering-grade high-voltage, synchronous, and hazardous-area electromagnetic motors manufactured to international IEC, UL, and CE standards.
Operating at the pinnacle of the industrial manufacturing landscape, Xi’an Lite SIMO Motor Co., Ltd stands as an elite force in the Chinese mechanical engineering sector. We specialize in the end-to-end design, custom fabrication, processing, mold building, and assembly of complex, large/medium-sized high-voltage AC motors, DC motors, synchronous units, and robust explosion-proof powerplants.
By integrating structural aerodynamics, premium magnetic materials, and advanced thermal management, SIMO provides global heavy industries with unmatched operational efficiency. Our manufacturing capacity and technical precision place us among the top-tier of industrial electric motor suppliers worldwide, servicing crucial sectors like power generation, mining, metallurgy, and petrochemical refining.
A history of technology accumulation, government partnership, and industrial globalization.
Covering 34 major series, 1,800 varieties, and over 19,500 distinct catalog specifications with output ranges from 0.35kW to 25,000kW.
We engineer YX, YXKK, YXKS series high-efficiency HV motors and YR, YRKK, YRKS wound rotor series. These units feature custom stator sizing, heavy steel framing, and dual-cooling loop designs suited for deep mining ventilators and high-capacity water pump installations.
Designed to comply with EU and US energy conservation protocols, our YE3, YE4, and YE5 motor series achieve ultra-premium IE4 and IE5 efficiency classifications. Together with YVFE3, YVFE4, and YVFE5 variable-frequency speed-regulating motors, they provide operational precision under changing load profiles.
Our YBX3, YBX4, and YBX5 explosion-proof motors prevent gas ignition in volatile environments. Engineered with flameproof enclosures, reinforced cable glands, and high thermal thresholds, they satisfy global Ex requirements for chemical facilities and offshore drill sites.
Understanding the critical variables of Total Cost of Ownership (TCO), material engineering, and factory-level selection.
In modern heavy industry, the initial purchase cost of an electromagnetic motor represents less than 3% of its lifetime operational costs. The remaining 97% is consumed by electrical energy. For global procurement officers sourcing from electromagnetic motor companies & factories, evaluating the efficiency curve is critical. Stator and rotor resistive losses account for over 60% of total electrical waste inside induction motors. By adopting copper-rotor architectures, low-loss silicon steel laminations, and refined radial ventilation fans, SIMO's YE5 and IE5 series minimize these losses, reducing heat generation and extending bearing grease life.
Furthermore, operating under variable loads demands variable frequency regulation. The YVFE3/YVFE4/YVFE5 systems prevent typical insulation breakdown associated with fast switching times (dV/dt) of variable speed drives (VSDs) by incorporating Class H insulated magnet wire and phase insulation barriers. This prevents premature motor failures and guarantees continuous plant operation.
High-voltage motors (such as the YKK, YKS, and YRKK series running on 6kV or 10kV lines) require advanced manufacturing control. The coils must undergo Vacuum Pressure Impregnation (VPI) with high-grade epoxy resins to eliminate air voids. Voids inside the winding slots can trigger partial discharges, leading to stator insulation breakdown under high thermal stress.
When specifying motors for large-scale mining mills or high-capacity compressors, synchronous motors like the TDMK and TK series offer unique advantages. Unlike standard asynchronous motors, synchronous motors can operate with a leading power factor, correcting the overall grid power factor of a mining facility and eliminating penalties imposed by utility companies.

Deep engineering insight into the R&D processes, material choice, and precision manufacturing setups that define SIMO Motor.
To optimize power density, SIMO engineers utilize finite element analysis (FEA) software to model electromagnetic fields and thermal profiles. This enables us to design stator slots that reduce harmonic losses and optimize ventilation paths. In high-voltage motors like the Y2 and YKS series, cooling efficiency is enhanced by strategically placed axial ducts, allowing airflow to cool the winding ends.
The performance of electromagnetic motors depends heavily on raw material quality. SIMO uses cold-rolled non-oriented silicon steel sheets, which offer high magnetic permeability and low core loss. Additionally, our windings are made from high-purity, oxygen-free copper, reducing copper losses and minimizing motor heating during high-current starts.
Rotor vibration is a primary cause of bearing wear. At our Xi'an plant, every rotor assembly undergoes dynamic balancing on computerized balancing machines. This guarantees vibration levels comply with ISO 1940 Grade G1.0/G2.5 specifications. Our designs reduce mechanical noise, lower bearing temperatures, and extend the mean time between failures (MTBF) to over 100,000 hours.
Certified validation of our engineering quality, safety performance, and cross-border regulatory compliance.
SIMO has established and maintains a rigorous quality management system certified under ISO9001. Our products carry international marks including the European Union's CE, the United States' UL safety listing, and the Eurasian Customs Union's GOST certificate. This alignment with global standards facilitates direct import, site inspection, and installation compliance in major industrial jurisdictions.
