Explore our tier-one range of customized, highly robust squirrel cage, explosion-proof, and variable-frequency AC and DC motors designed to match dynamic mechanical challenges.
As industrial automation, pump stations, mining extractions, and heavy manufacturing process scales rapidly expand globally, the requirement for highly durable, low-maintenance electrical powertrains has surged. Xi’an Lite SIMO Motor Co., Ltd. (historically recognized as SIMO Motor) operates as one of China’s leading industrial motor developers, specializing in high-performance high/low voltage squirrel cage motors, wound rotor slip-ring systems, DC motors, and certified explosion-proof drives.
Our squirrel cage designs stand at the center of this product matrix. Characterized by their rugged structure, minimal maintenance dependencies, and high operational reliability across extreme thermal and mechanical environments, our rotor configurations integrate cutting-edge magnetic path optimizations. By leveraging premium copper rotor slots and advanced lamination stamping, our motors are built to decrease rotor losses ($I^2R$) and prevent dynamic slip degradation, making SIMO the top-ranking manufacturer for enterprises seeking robust power generation at scale.
For over six decades, our enterprise has continually adapted to industrial paradigm shifts, progressing from a state-owned repair workshop to a multi-subsidiary global motor manufacturer.
SIMO Motor established under state ownership, pioneering industrial repairs and structural testing processes.
Relocated to a dedicated manufacturing facility in Xi'an city, establishing heavy production lines.
Rebranded as Xi'an Motor Factory after deep integration with regional electrical engineering groups.
Reformed into a modern joint-stock limited company, allowing rapid technical capital investments.
SIMO Motor Group founded, coordinating manufacturing across 14 specialized subsidiaries.
Moved to a state-of-the-art high-tech industrial park, integrating computerized CNC systems.
Re-organized as Tech Full Simo Motor, optimizing global procurement and logistics pipelines.
Reaffirming our place as a leader in IE4 and IE5 ultra-premium efficiency asynchronous drive development.
SIMO maintains dynamic design capabilities covering over 34 major motor series, spanning 1,800 varieties and more than 19,500 customizable engineering specifications.
Featuring YX, YXKK, YXKS high-efficiency high-voltage induction series. Optimized stator slot geometry combined with vacuum-pressure impregnated class-F insulation yields maximum reliability. Output ratings scale up to 25,000 kW.
Our YE3, YE4, and YE5 (Ultra Premium) lines offer some of the industry's lowest electromagnetic losses. The rotor configurations integrate high-purity aluminum casting or fabricated copper cages to satisfy rigid environmental targets.
For heavy industrial environments, our YBX3, YBX4, and YBX5 explosion-proof low-voltage/high-voltage motors offer safe operation under gaseous, petrochemical, and volatile dust hazards. Certified according to EU CE and international standard baselines.
Additionally, we supply specialized T, TD, TK, TDMK series synchronous motors, large scale TFW synchronous generators, and Z2, Z4, and Z DC motors for high-torque laminating mills and metal extruders. Our dynamic power envelope ranging from 0.35 kW up to 25,000 kW allows us to equip operations across metallurgy, petrochemicals, power grids, and high-performance agricultural water systems.
Delivering high-integrity propulsion drives tailored to the engineering parameters of specific vertical markets globally.
Underground extraction processes subject machinery to continuous vibrations, abrasive coal dust, and flammable gas accumulation. SIMO's YBK3 explosion-proof motors utilize cast-iron frame integrity with IP55 protection, resisting hazardous environments while maintaining reliable shaft torque under peak loads.
Refineries require precise ventilation and high-volume fluid pumps operating 24/7. Our range of YBX3, YBX4, and YBX5 Ex-proof motors prevent thermal ignition risks. Engineered to support high startup torque under low starting current ($I_{st}/I_{n}$), they minimize electrical system stress.
With massive head heights and shifting volume flows, municipal water systems rely on variable-frequency setups. SIMO's YJP variable frequency motors adjust torque across wide speed intervals, minimizing cavitation risks and lowering overall energy demand.
Global procurement teams prioritize cost efficiency, regulatory compliance, and rapid customization when selecting squirrel cage motors. SIMO addresses these requirements through detailed engineering support. From standard frame sizes to custom shaft configurations, we minimize system integration challenges.
The transition toward Industry 4.0 demands intelligent powertrains. SIMO's engineering team is actively integrating smart sensors directly into stator structures to track critical parameters:
SIMO maintains certified operations under ISO9001 Quality Systems, European Union CE, American UL, and Russian GOST standards, ensuring full compliance for international operations.
Every motor undergoes structural testing, including winding resistance verification, insulation resistance testing, no-load verification, dynamic rotor balance analysis, and vibration measurements. This rigorous approach ensures each motor delivers reliable performance in heavy-duty applications.
Answers to key engineering questions regarding squirrel cage motors, start-up topologies, and operational safety.
