Xi’an Lite SIMO Motor Co., Ltd — A Global Pioneer in Heavy Industrial Motor Engineering
Xi’an Lite SIMO Motor Co., Ltd is an elite electric enterprise, serving as a primary pillar enterprise specializing in the manufacturing of large/medium-sized, high/low voltage AC motors, DC motors, synchronous motors, and explosion-proof motors within China’s mechanical engineering industry. SIMO stands as a comprehensive manufacturing and service powerhouse, integrating advanced motor design, precise manufacturing, high-end mechanical processing, mold making, and meticulous structural assembling. Ranking at the very top of China’s motor manufacturing sector in terms of production scale and technical complexity, the company maintains an aggressive, fast-growing development trajectory across global markets.
Tracing over six decades of continuous industrial innovation, technological adaptation, and structural reform.
SIMO Motor established and directly guided by the national government, laying the cornerstone for heavy electrical machinery in China.
Relocated to a newly constructed, state-of-the-art plant in Xi'an city to expand manufacturing capacity.
Officially renamed to Xi'an Motor Factory following comprehensive technological acquisitions and regional enterprise integrations.
Successfully reformed from a state-owned factory into a modern limited liability company, streamlining market competitiveness.
Establishment of the SIMO Motor Group, consolidating 14 specialized industrial subsidiaries.
Transitioned operations to an advanced high-tech industrial park equipped with ultra-modern precision tools.
Corporate identity upgraded to Tech Full Simo Motor, reinforcing digitalization and global export standards.
Continuous progression toward becoming the undisputed global benchmark for custom electric AC and DC motor manufacturing.
The Company was founded originally in 1955, boasting more than 60 years of heritage in motor manufacturing and global distribution. Supported by a robust registered capital of 21.5 million RMB, SIMO operates 3 advanced manufacturing factories and 1 specialized subsidiary facility. Total fixed assets reach 380 million RMB, housing more than 1,172 sets of high-precision equipment.
Our technological prowess is driven by over 1,200 dedicated professionals, including a specialized R&D taskforce of more than 260 technical engineers. This elite group includes 21 senior engineers and 15 principal expert engineers who spearhead customized motor topology design and computational electromagnetic optimization.
Analyzing modern macroeconomic forces, supply chain resilience, and the transition toward ultra-efficient industrial drive systems.
Global industrial sectors—spanning mining, petrochemicals, power generation, and heavy manufacturing—face intense regulatory pressure to minimize carbon footprints. Procurement officers are actively replacing legacy motors with IE4 and IE5 ultra-premium efficiency AC motors to reduce lifecycle energy costs and comply with rigorous international environmental mandates.
China's smart manufacturing transformation (Factory 4.0) has revolutionized motor production. By integrating automated robotic winding, AI-driven quality inspection, and IoT-enabled precision balancing, manufacturers like SIMO deliver unmatched supply chain resilience, scaling production output without compromising strict tolerance benchmarks.
Standard off-the-shelf motors often fail in extreme duty cycles. Custom electric AC motor engineering requires proprietary electromagnetic simulation, thermal class H insulation systems, and tailored IP55-IP68 enclosures. Providing deep architectural customization gives global buyers a distinct competitive uptime advantage.
Engineered for all industrial environments across 34 major series, 1,800 varieties, and 19,500 distinct specifications.
