Direct supply line of SIMO high-performance direct current (DC) and alternating current (AC) high-voltage asynchronous motors.
Established as a foundational pillar of the Chinese mechanical industry, Xi’an Lite SIMO Motor Co., Ltd. has developed into a premier comprehensive manufacturing enterprise specializing in the design, mechanical tooling, casting, assembly, and testing of large-scale and medium-sized industrial motors. By prioritizing technological iteration and customer-specific engineering, SIMO ranks at the top tier of China's electrical manufacturing sector.
Our heavy-duty infrastructure and system portfolio provide critical propulsion technologies across domestic and international markets, driving process plants, mining operations, offshore oil complexes, municipal water plants, and massive power generation facilities.
Over 60 years of progressive evolution from a state-owned repair workshop to a global manufacturer of advanced electrical machines.
Deploying specialized rotor dynamics, high-insulation stabilities, and structural resilience across 34 main product families.
Represented by YX, YXKK, and YXKS series, engineered to operate under high-voltage thresholds (6kV to 10kV). Provides high efficiency, optimized thermal performance, and low structural vibration levels.
YBX3, YBX4, and YBX5 series. Engineered for hazardous gas and dust environments in petrochemical processing and underground coal mining operations. Fully certified for ATEX and IECEx compliance.
Z2, Z4, and large Z series DC motors. These systems deliver precise variable speed regulation, high starting torque, and reliable performance in rolling mills, extrusion systems, and heavy marine winches.
SIMO's R&D capability supports a comprehensive power envelop spanning from 0.35kW to 25,000kW, offering over 34 series, 1,800 distinct configurations, and more than 19,500 system specifications. Our line integrates YE3, YE4, and YE5 premium high-efficiency asynchronous induction systems alongside energy-efficient variable frequency configurations (YVFE3, YVFE4, YVFE5). For heavy-duty synchronization, we manufacture T, TD, TK, and TDMK synchronous systems specifically configured for high-torque mine milling mills and heavy industrial fans, alongside TFW large-scale synchronous generators.
Leveraging high-capacity industrial clusters and smart automation to maintain structural cost efficiency and lead-time reliability.
Featuring 1,172 sets of high-precision fabrication systems, including CNC boring mills, high-capacity dynamic balancing equipment, automated laser-guided stator core stampers, and computerized coordinate measuring machines (CMM).
Our computerized VPI insulation systems process high-voltage stator coils under deep vacuum using high-grade epoxy resins. This eliminates air voids, secures coil-to-core adhesion, and delivers Class F/H thermal resistance.
By sourcing raw materials—such as low-loss cold-rolled silicon steel sheets (e.g., 50W270) and high-purity electrolytic copper wire—directly from local Tier-1 metallurgical complexes, SIMO reduces pricing volatility and secures predictable delivery timelines.
Aligning global electrical drive engineering with efficiency regulations, materials engineering, and digital twins.
Simo is moving its asynchronous induction ranges to IE4 and super-premium IE5 efficiency metrics. By optimizing rotor slots, using low-loss magnetic silicon steels, and refining cooling configurations, our designs reduce energy consumption and help lower operational costs.
Our next-generation medium and high-voltage motors support integrated wireless sensor arrays. These sensors monitor temperature, vibration, and stator current metrics in real-time, allowing operators to transition from reactive maintenance to predictive scheduling.
We design stator insulation configurations that resist voltage spikes caused by PWM inverter drives. This is achieved by utilizing insulated bearings (such as hybrid ceramic designs) and grounding brushes to prevent shaft currents and electrical erosion.

Configured heavy-duty propulsion systems tailored for demanding engineering environments.
TDMK synchronous and high-torque wound rotor systems (YRKK) drive ball mills, jaw crushers, and overland conveyors. These motors provide high starting torque and handle dust-heavy environments.
YBX3, YBX4, and YFB3 explosion-proof motors provide reliable operation for gas compressors, refinery transfer pumps, and aeration blowers working in volatile atmospheres.
YXKK high-voltage AC motors power coal mills, boiler feed pumps, and draft fans. This helps maintain high operational availability in thermal and hydro-electric stations.
High-voltage vertical and horizontal induction motors (YKS, YKK) power large drainage pumps, agricultural irrigation systems, and municipal water purification works.
SIMO's quality control systems follow structured protocols to verify motor performance and safety. Our manufacturing facility complies with ISO9001 Quality Management Systems and holds certifications for major global markets, including European CE, American UL, and Russian GOST certificates.
Every motor undergoes comprehensive testing before shipment, including stator surge testing, winding resistance verification, no-load and full-load running tests, and dynamic vibration analysis. This testing helps ensure reliable installation and commissioning at the project site.
Streamlined processes from initial design specification to international customs clearance and commissioning.
Our engineers can adapt shafts, mounting footprints, and connection boxes to match legacy equipment, helping to simplify retrofitting processes.
We work with international logistics providers to coordinate containerized packing, rust-proof preparation, and customs documentation, supporting timely delivery to major ports globally.
We provide remote engineering guidance for initial alignment and start-up, along with onsite supervision for major projects, helping to ensure the correct integration of complex motor drives.
Addressing engineering questions regarding configuration, electrical safety, and project execution.
Specialized motors designed for dust safety, explosion protection, and high-temperature conditions.
