Engineered to withstand extreme environments, delivering optimal torque density, mechanical reliability, and international standard efficiency levels.
In the contemporary landscape of heavy industries, High Voltage (HV) Motors serve as the primary kinetic workhorses. Whether driving large-scale slurry pumps, massive air compressors, ore millers, or chemical agitators, the efficiency and thermal durability of these machines directly define plant uptime and profitability.
Globally, industrial facilities are aggressively optimizing their energy intensity in compliance with modern carbon reduction mandates. Choosing the right HV motor manufacturing partner is no longer just about horsepower; it is about procuring high-performance machine architectures that combine advanced stator insulation technology (VPI), superior thermal dissipation, and custom engineering adaptations tailored for local operating parameters.
Xi'an Lite SIMO Motor stands at the leading edge of this paradigm. As one of China's premier motor manufacturing giants, SIMO blends comprehensive engineering expertise, highly responsive custom fabrication capabilities, and certified compliance matrices to service the global industrial sectors.

Successfully reformed into a limited liability company from a state-owned factory to drive market integration.
SIMO Motor Group established, organizing 14 specialized manufacturing and processing subsidiaries.
Moved to the modern high-tech industrial zone, deploying advanced processing equipment and automated testing lines.
Officially renamed to Tech Full Simo Motor, aligning with high-efficiency motor R&D directions.
Continuing the legacy of high-voltage motor innovation to act as one of the best motor manufacturers worldwide.
SIMO's R&D covers 34 major series, 1,800 varieties, and over 19,500 individual specifications, spanning power ratings from 0.35kW up to 25,000kW.
Featuring YX, YXKK, and YXKS high-efficiency high-voltage three-phase asynchronous motors. Designed with box-type steel structures for optimized magnetic field distribution, these motors offer high efficiency, low vibration, and superior structural rigidity.
Designed as YR, YRKK, and YRKS wound rotor high-voltage motors, ideal for applications requiring high starting torque under minimal starting currents, or adjustable speed ranges via external rotor resistance.
Our heavy industrial T, TD, TK, and TDMK series synchronous motors are specifically engineered for heavy milling plants in mining and cement manufacturing, enabling power factor correction for the plant's overall grid.
Featuring certified YBX3, YBX4, and YBX5 high and low voltage three-phase explosion-proof asynchronous motors, engineered for underground coal mining gas atmospheres and offshore chemical installations.
YVFE3, YVFE4, and YVFE5 variable frequency high/low voltage motors feature insulated non-drive end bearings to eliminate shaft currents under high-frequency PWM switching frequencies.
Our renowned Z2, Z4, and Z series large/medium-sized DC motors support metallurgical rolling mills, extruders, and mine hoists requiring continuous speed variation and high overload factors.
Different regions and industries demand varied engineering methodologies. Here is how SIMO designs adapt to target applications.
In dust-heavy, high-shock vibration mining environments, mill motors face severe loads. SIMO TDMK synchronous motors provide high-torque power factors for sag and ball mills, featuring dust-proof enclosures (IP54/IP55) and reinforced bearing structures to eliminate stator-rotor contact hazards.
Operating pumps and blowers in volatile gas environments demands strict explosion protection. SIMO's flameproof explosion-proof motors are constructed with robust cast iron enclosures capable of containing internal explosions without risk of igniting the external ambient atmosphere.
Water-cooled YKS motors run continuously in pumping stations. Utilizing air-water heat exchangers, these motors minimize external thermal radiation, ensuring efficient running during prolonged municipal flood control or water transfer operations.
Steel roll milling requires rapid start-stops, dynamic speed regulation, and heavy overload capacity. Our heavy DC Z series motors are engineered with advanced copper commutators and Class H insulation to withstand rapid cyclic currents without sparking or insulation breakdown.
A key factor in SIMO's global competitive edge is the resilience and scale of China's heavy electrical manufacturing supply chain.
Raw Material Integrity: We source high-grade non-oriented cold-rolled silicon steel sheets (such as 50W470 or 35W300 grades) directly from premier Chinese metallurgical mills. This guarantees low core loss and excellent magnetic permeability across all operating frequencies.
Integrated Component Ecosystem: From copper bar extruders to specialized insulation manufacturers, SIMO relies on a robust industrial ecosystem to secure critical raw materials without international lead-time fluctuations.
Highly Skilled Engineering Pool: Backed by Xi'an's major technical universities, SIMO maintains an active R&D division of 260+ engineers and 15 senior expert engineers, driving constant improvements in electric machine design.
How SIMO is leading the transition towards smart, ultra-efficient rotating equipment.
In step with global MEPS (Minimum Energy Performance Standards), SIMO is transitioning its high-voltage and low-voltage motors toward IE4 and IE5 standards. Utilizing electromagnetic optimization and premium grade copper, we reduce internal core losses to decrease total cost of ownership (TCO) for plant owners.
Our upcoming motor series are configured with integrated PT100 temperature sensors and dual-axis vibration sensors. Operating through modbus/wireless gateways, these systems communicate with plant SCADA software to support predictive maintenance, avoiding sudden downtime events.
SIMO is developing solventless varnish and eco-resins for VPI processes. This lowers VOC emissions during manufacturing while maintaining thermal stability up to Class H ($180^\circ\text{C}$) thresholds.
SIMO has passed ISO9001 Quality System Certification, EU "CE", US "UL", Russian "GOST", and CSA approvals. Our electric motors are widely applied globally in power generation, coal mining, petroleum refining, chemical engineering, and water conservancy.
