B2B procurement agents searching for a "discount electric motor store" are not seeking cheap, low-grade alternatives. They are looking to optimize their capital expenditures (CAPEX) without exposing critical operations to unplanned downtime. Factory-direct sourcing represents the only true avenue to capture these margin optimizations legally and safely.
With regulations phasing out IE1 and IE2 motors, the industry standard has shifted decisively to IE4 (YE4 series) and IE5 (YE5 series) super-premium efficiency systems. These modern motors reduce thermal losses, extend winding lifetime, and yield multi-million dollar utility savings over decade-long operation spans.
Xi’an Lite SIMO Motor Co., Ltd is an electric company and main enterprise specializing in the manufacturing of large/medium-sized, high/low voltage AC motors, DC motors, synchronous motors, and explosion-proof motors in the Chinese mechanical industry.
SIMO is a comprehensive manufacturing and service supplier of motor design, manufacturing, mechanical processing, mold making, and precision assembly. The Company ranks TOP in China’s motor industry as to its scale of production and has maintained a fast-growing development trend for consecutive years.
SIMO Motor established and led by the state government, laying the blueprint for heavy electrical engineering in Western China.
Relocated to the newly built state-of-the-art plant in Xi'an city, scaling up initial heavy machinery casting.
Renamed to Xi'an Motor Factory after a series of successful state-level acquisitions and process integration.
Reformed into a highly efficient limited company from a state-owned factory to match modern market dynamics.
Establishment of SIMO Motor Group, integrating 14 structural subsidiaries for end-to-end industrial supply chain control.
Moved operation headquarters to the high-tech industrial park, setting up advanced CNC tooling and insulation assembly lines.
Officially restructured and modernized under Tech Full Simo Motor, optimizing global distribution operations.
Consistently advancing as a world-class electric motor developer with active export networks in over 40 countries.
Operating out of China's primary machinery hub, SIMO leverages complete downstream and upstream integration. From high-grade electrical steel sheeting (silicon steel) to automated copper wire winding operations, our factory manages everything in-house. This cuts out distributor markups, allowing us to serve as a high-quality "discount" store for international purchasers without undercutting engineering standards.
We are driving the integration of Industry 4.0 diagnostics directly into our motor chassis. Future designs feature custom cavities for vibration sensors, temperature RTDs, and remote wireless health monitoring. This minimizes catastrophic failure risks and maximizes continuous production run-time.
Simo Motors are engineered for global compliance. Whether operating under CE rules in the EU, UL guidelines in North America, or GOST standards in Central Asia, our products hold full structural certifications. Local partnerships provide technical assistance, replacement parts, and dynamic warranty services globally.
Our R&D covers 34 major series, comprising over 1,800 varieties and 19,500 distinct specifications. Power ratings scale from 0.35 kW up to 25,000 kW, suitable for all types of industrial drives.

SIMO has passed the ISO9001 Quality System Certification, European Union "CE", United States "UL", and Russian federation "GOST". Our motors serve major international projects across dozens of sectors.
Simo motors are engineered for highly complex environments, where standard electric motors would fail within weeks. Here is how our specialized series operate under extreme field conditions.
Underground mines present extreme challenges due to high levels of abrasive ambient dust, moisture, and explosive gas mixtures. The YBK3 series flameproof motors are designed specifically for underground coal mines. Featuring robust cast-iron frames and tight flameproof enclosures, they power conveyor belts, heavy-duty ventilation fans, and coal cutters safely without the risk of sparking.
Process piping loops transport flammable gases under high pressure, making explosion protection a strict regulatory requirement. SIMO’s YBX4 and YBX5 Series Three-phase Asynchronous Ex motors prevent electrical arcs from contacting hazardous atmospheres. Certified under global Ex-d and Ex-tb standards, they reliably drive oil pump systems and gas compressors 24/7.
Moving large volumes of water requires continuous power and high motor efficiency. SIMO’s YKS high-voltage three-phase asynchronous motors (featuring advanced air-to-water cooling systems) are the preferred choice for major irrigation networks, municipal treatment plants, and industrial water systems.
Get answers to common technical, commercial, and logistical questions from engineers and procurement teams.
A: All three are high-efficiency, high-voltage three-phase induction motors, but they feature different cooling and protection designs:
A: Yes. Our YVFE3, YVFE4, and YVFE5 series are specifically engineered for variable frequency speed regulation. They feature reinforced Class F/H insulation systems, vacuum-pressure impregnated (VPI) windings, and options for insulated non-drive end bearings to eliminate harmful shaft currents.
A: The YE5 series meets the ultra-premium efficiency standard (equivalent to IEC 60034-30-1 IE5). Compared to IE3 (YE3) and IE4 (YE4) motors, it reduces energy losses by up to 20% and 10% respectively. For a 250 kW motor running 8,000 hours annually, upgrading to IE5 can save thousands of kilowatt-hours, paying back the initial cost difference within the first 12 to 18 months.
A: Our explosion-proof series (YBX3, YBX4, YBX5, YBK3, YFB3, and YFB4) conform to strict Chinese national GB standards (equivalent to international IEC 60079 series). They carry certificates for hazardous gas (Ex d I Mb for underground coal mines, Ex d IIB T4 Gb for refineries) and combustible dust (Ex tD A21 IP65 T135°C for grain mills and textile processing areas).
A: Xi'an Lite SIMO Motor is a direct manufacturer, not a trading company. We source raw materials directly, run an automated 1200+ employee factory, and manage assembly in-house. This complete supply chain integration allows us to offer factory pricing to our partners, providing high-quality motors without the steep markup of Western brands.
