Explore our heavy-duty synchronous and asynchronous high-voltage and low-voltage motors built to withstand continuous industrial operations.
Xi’an Lite SIMO Motor Co., Ltd stands as a premier pillar in the Chinese mechanical fabrication industry, specializing in the design, development, and manufacturing of large/medium-sized, high/low voltage AC motors, DC motors, synchronous motors, and specialized explosion-proof electric motors. As a comprehensive mechanical integration supplier, LITESIMO delivers turnkey engineering solutions spanning custom mechanical mold making, precision automatic processing, coil winding, Vacuum Pressure Impregnation (VPI), dynamic balancing, and performance validation.
We rank consistently at the top of China's heavy motor manufacturing sector regarding physical asset capitalization, engineering research capacity, and export volume. Guided by decades of scientific methodology and quality benchmarks, we offer worldwide mechanical contractors a reliable, robust source of mechanical power optimized for continuous high-load service.
The global drive system industry is undergoing a paradigm shift towards decarbonization, intelligence, and hyper-efficiency. High-powered electric motor systems must evolve beyond simple electromechanical converters to become digitized, feedback-driven nodes within larger industrial automation ecosystems. Below is the roadmap LITESIMO leverages to engineer the next generation of high-powered industrial motors:
Utilizing cold-rolled non-oriented silicon steel sheet cores with extremely low core losses (such as 50CS270 grades), optimized rotor slot geometry, and permanent magnet-assisted synchronous reluctance (PMASynRM) technologies to satisfy the stringent requirements of international IE4 and IE5 efficiency indices.
To mitigate the effects of rapid dV/dt voltage spikes common with IGBT variable frequency drives, we implement custom formulation resin-rich mica tape wrapping, high-rigidity corona-shielding varnishes, and double Vacuum Pressure Impregnation (VPI) cycles ensuring class H thermal resistance and complete elimination of internal air voids.
Integrating direct rotor winding temperature RTDs, dual-channel accelerometer casing vibration sensors, and inductive shaft-current grounding arrays, linked to edge computing nodes for proactive failure prediction and real-time operational diagnostics.
High-powered electric motors do not operate in isolation; they are core components of massive mechanical chains. LITESIMO provides application-focused industrial drive solutions that match the precise dynamic torque characteristics required by major industrial ecosystems:
Underground operations pose massive hazards from explosive coal dust and methane gas release. Our YBK3 and YFB3 explosion-proof series provide certified dust and gas flameproofing, high startup torque configurations to overcome high-inertia loaded conveyor belt systems, and rugged cast-iron enclosures (IP55/IP56) designed for abrasive atmospheres.
We provide continuous-duty YBX3, YBX4, and YBX5 explosion-proof motors certified for Class I, Division 1 and 2 environments. Engineered with non-sparking terminal boxes, special corrosion-resistant epoxy paints, and labyrinth shaft seals, these units prevent volatile vapor ignition while running high-capacity hydrocarbon pumps and gas compressors.
Heavy water pumps require massive horsepower and stable long-term operation. Utilizing our high-voltage YKK and YKS water-to-air or air-to-air cooling options, municipal water stations achieve uninterrupted power output up to 25,000 kW, coupled with custom vertical-mount frames (IM V1) to minimize footprint.
Operating from Xi'an, the historic industrial engineering hub of China, LITESIMO's manufacturing facilities are designed around lean-production principles. Our integration of advanced tooling and localized supply chains guarantees prompt delivery and unmatched product quality:
With more than 1,172 sets of high-precision heavy-duty manufacturing equipment, our production capacity handles components of immense scale. Key capital equipment includes:
This concentration of high-end equipment allows us to retain complete process control internally, eliminating sub-contractor delay risks and ensuring consistent physical dimensional tolerances on custom structural frames.

To operate seamlessly within local utility grids and regulatory frameworks, high-powered electric motors must carry appropriate electrical and safety marks. LITESIMO maintains an extensive certifications matrix, ensuring that we satisfy international safety codes and quality regimes:
Every motor undergoes testing in our state-certified laboratory prior to dispatch. Standard protocols include phase-to-phase and phase-to-ground insulation resistance testing, stator winding polarization index (PI) determination, no-load vibration level detection, and heat run trials under simulated load curves. Full structural testing packages are certified by third parties like Lloyd's, SGS, or Bureau Veritas upon client request.
To bridge global geographical distances, LITESIMO provides comprehensive documentation packages, local commissioning advice, and direct digital support. Our design engineers coordinate directly with your systems integrators to confirm shaft dimensional compliance, custom mounting terminal box orientation, and sensor-loop configuration, ensuring seamless integration with existing site equipment.
With more than 60 years of dedicated motor manufacturing experience, we have consistently adapted to global industrial standards and technological advancements:
