Engineered for high efficiency, explosive proof safety, and custom mechanical retrofits
Analyzing technical retrofits, physical parameters alignment, and systemic electrical calculations
Replacing a medium or high-voltage electric motor in a heavy industrial environment requires more than comparing nameplate ratings. It demands deep compatibility evaluation, thermal analysis, structural alignment, and transient response auditing to prevent catastrophic down-time.
Matching old NEMA or IEC frames requires custom transition bases or machined shafts to ensure precise coupling without structural vibration issues.
Upgrading to high-efficiency motors requires careful planning around starting currents, VFD harmonics, and cable insulation integrity under dV/dt stress.
Replacing motors in petrochemical plants and coal mines requires strict adherence to ATEX, IECEx, or Class I Div 2 certifications to prevent ignitions.
SIMO Motor ranks as a leading enterprise in China's machinery industry, specializing in large, medium, and high/low voltage AC motors, DC motors, synchronous motors, and explosion-proof motors. We combine motor design, manufacturing, mechanical processing, mold building, and assembly under one roof to deliver comprehensive industrial drive solutions.
How SIMO Motor evolved from a local plant into a global leader in high-performance electric machinery
SIMO Motor established and led by government initiatives to kickstart domestic heavy industry machinery production.
Moved the entire manufacturing base to the new plant in Xi'an city, scaling up production lines for early-stage standard motors.
Renamed to Xi'an Motor Factory following a series of strategic state-led acquisitions and manufacturing integration.
Reformed into a limited liability company from a state-owned enterprise, bringing agile management to industrial motor production.
SIMO Motor Group established, organizing 14 specialized subsidiaries for raw materials, testing, and component logistics.
Relocated to a modern, high-tech plant equipped with advanced CNC machining centers and vacuum-pressure impregnation (VPI) equipment.
Rebranded to Tech Full Simo Motor, expanding direct export channels to European, Middle Eastern, and American industrial markets.
Recognized as a leading high-efficiency, explosion-proof, and custom high-voltage motor manufacturer, pioneering next-gen IE4 and IE5 drive solutions.
Why domestic vertical integration translates to fast lead times and cost-effectiveness for global industries
By producing our own laminations, rotor shafts, copper windings, and castings, we eliminate shipping delays. This ensures lead times are kept short for custom industrial retrofits.
Our location in Xi'an places us near top-tier engineering universities and research centers. This allows us to rapidly prototype, test, and manufacture complex custom motor structures.
We feature full-load test beds for motors up to 25,000 kW. Every replacement motor is thoroughly tested under load before shipping, minimizing the risk of commissioning delays.
| Motor Series | Power Range | Voltage Options | Key Application Scenario |
|---|---|---|---|
| YX / YXKK / YXKS | Up to 25,000 kW | 6kV, 10kV, 11kV, 13.8kV | Large scale fans, water pumps, compressors in steel and chemical plants. |
| YR / YRKK / YRKS (Wound Rotor) | Up to 15,000 kW | 3kV, 6kV, 10kV | High starting torque loads like ball mills, crushers, and mine hoists. |
| YBX3 / YBX4 / YBX5 | 0.55 kW to 3,000 kW | 380V, 660V, 1140V, 6kV, 10kV | Explosion-proof environments, chemical plants, oil & gas refineries. |
| TDMK / T / TK (Synchronous) | Up to 20,000 kW | 6kV, 10kV | Heavy-duty mining machinery requiring power factor correction. |
| Z4 / Z (DC Motors) | Up to 3,000 kW | 220V, 440V, 660V | Extruders, paper mills, rolling mills requiring wide-range speed regulation. |
Proven custom motor replacement solutions across demanding operating environments
Replacing older IEEE 841 and flameproof motors with our Class I Division 1 & 2 certified YBX4 series. These custom shaft configurations align perfectly with legacy pumps, cutting refinery retrofit costs by 40%.
Custom TDMK synchronous motors deployed in copper and gold mining sites in Chile and Peru. These systems are built to withstand high altitudes and dust, offering built-in power factor correction to lower overall site utility costs.
Upgrading municipal pumps to IE4 and IE5 variable-frequency YVFE3 and YVFE4 motors. These units integrate with existing district heating control systems to lower municipal energy usage by up to 22% during peak winter loads.
Pioneering the next generation of smart, ultra-efficient industrial drivetrains
As the industry shifts toward carbon neutrality and smart factory automation, the technologies behind industrial electric motors are undergoing significant changes. Our product roadmap focuses on three main developments:
Using advanced silicon steel laminations and optimized rotor geometry to reduce core losses. These modifications help our induction and synchronous motors meet and exceed the strict IE5 international efficiency standards.
Equipping replacement motors with built-in vibration, temperature, and magnetic flux sensors. This telemetry feeds directly into plant SCADA systems, enabling predictive maintenance that helps prevent unexpected downtime.
Using Class H insulation combined with modern Vacuum Pressure Impregnation (VPI) resins. This design protects winding systems from voltage spikes caused by high-frequency Variable Frequency Drives (VFDs).
Ensuring compliance with global safety, efficiency, and environmental regulations
SIMO Motor holds quality system certifications including ISO9001, EU CE, US UL, and Russian GOST. Our motors are widely used in mining, metallurgy, transportation, oil and gas, and chemical industries worldwide.
