Explore our diverse lineup of premium heavy-duty electric motors engineered for maximum reliability under extreme conditions.
Totally Enclosed Fan Cooled (TEFC) three-phase asynchronous motors represent the critical machinery of heavy industry. Characterized by their fully sealed frames and external cooling fans, TEFC motors prevent external ambient air from entering the internal housing, making them indispensable in harsh, dusty, or moisture-laden settings. In a macro-industrial context focused on decarbonization, operations managers seek powertrain units that offer more than basic reliability—they require optimized energy profiles, smart-system integration, and a low Total Cost of Ownership (TCO).
“The global mandate for high energy efficiency and predictive intelligence has shifted TEFC 3-phase motor design from standard mechanical construction to a system of customized mechanical, electrical, and thermal optimization.”
Standard motors often fail to meet the performance margins needed for heavy-duty environments. In chemical, petrochemical, mining, and metallurgy sectors, customized TEFC 3-phase motors are required to address specific mechanical and thermal stresses:
Through close technical collaboration, custom TEFC 3-phase motor manufacturers configure frame sizes, shaft dimensions, and mounting geometries to ensure seamless integration into existing plants, reducing downtime during system upgrades.
China's industrial motor manufacturing sector has transitioned from mass production to high-precision engineering. Xi'an Lite SIMO Motor Co., Ltd leads this transformation by combining established production infrastructure with advanced technology. Supported by local supply chains, SIMO secures premium raw materials—such as low-loss cold-rolled silicon steel and high-purity copper—ensuring high efficiency in every motor.
Our facility handles every phase of production in-house, including stator winding, high-vacuum pressure impregnation (VPI), automated machining, and rotor dynamic balancing. This integration supports strict quality control and enables the customization of complex electrical designs, including low-voltage high-efficiency systems and high-voltage three-phase asynchronous motors.
A legacy of manufacturing excellence and continuous innovation in heavy industrial motor technology since 1955.
SIMO Motor is established and led by the government, laying the foundation for industrial electric motor manufacturing in Northwestern China.
The factory relocates to its primary plant in Xi'an, expanding production capacity to support national infrastructure projects.
Renamed Xi'an Motor Factory following series acquisitions and the integration of regional mechanical component manufacturers.
Successfully reforms from a state-owned factory into a limited liability company, driving market-led innovation and expanding export pipelines.
Establishment of the SIMO Motor Group, consolidating 14 specialized subsidiaries across electric motor design, mold making, and alloy casting.
Relocates to a high-tech facility equipped with advanced CNC winding, automated insulation processing, and testing systems.
Rebranded as Tech Full Simo Motor, aligning corporate strategy with premium international standards, including CE, UL, and GOST.
Continues as a leading manufacturer of high/low voltage, explosion-proof, and DC motors, delivering engineering solutions globally.
Modern industrial operations require motor solutions designed for specific application environments. As a leading custom motor supplier, Tech Full Simo Motor designs systems for a variety of demanding industrial sectors:
Ore grinding mills, conveyors, and ventilation fans operate in abrasive, dusty conditions. The TDMK series AC synchronous motors deliver high torque at low speeds to handle high starting loads without premature winding wear.
To address safety risks in explosive gas and dust environments, the YFB3, YFB4, and YBX5 explosion-proof series provide certified flameproof containment, preventing internal sparks from igniting external atmospheres.
Rolling mills and metal tensioning systems require fast, precise torque response. The Z4, Z2, and Z series DC motors provide wide speed ranges and high thermal capacity to handle demanding reversing cycles.
With tightening environmental regulations and rising electricity costs, efficiency has become a critical operational requirement. Standard three-phase motors can account for up to 70% of a plant's total energy consumption. Modernizing to ultra-premium efficiency standards is key to reducing utility costs and carbon footprints.
Our YE4 (IE4) and YE5 (IE5) series motors utilize optimized stator slot geometries and low-loss silicon steel laminations to reduce magnetic and windage losses. This design lowers operating temperatures, extends bearing life, and helps industrial plants meet environmental compliance requirements.
Simo motors are manufactured in compliance with international quality standards. We maintain certifications for major global markets to ensure regulatory compliance and operational safety.
Engineered for specialized industrial configurations, our custom systems provide stable power across varying voltage ranges.
