Engineered to operate seamlessly in volatile atmospheres. Explore our primary selection of flameproof, dust-ignition proof, and high-voltage induction motors.
In high-risk heavy industrial landscapes like oil refineries, chemical plants, and underground mines, explosive mixtures of gases, vapors, or combustible dust particles represent an ever-present hazard. Achieving absolute operational safety requires electric machinery capable of containing any internal electrical ignition source.
Medium Voltage (MV) Explosion-Proof (Ex) Motors, such as the YBX3, YBX4, and YBX5 series, are designed precisely for this purpose. They implement rugged, heavy-walled enclosures to prevent any internal spark, arc, or high temperature from igniting the surrounding hazardous environment. By relying on highly advanced flamepaths (joints designed with extremely tight tolerances), these motors cool escaping hot gases before they reach the outside air, ensuring absolute process safety.
Engineered to withstand the pressure of an internal explosion while preventing flame transmission to the surrounding atmosphere.
Prevents the ingress of explosive dust layers (Zone 21 & 22) through precision labyrinth sealing and specialized IP65/IP66 enclosures.
Meets IE3, IE4, and the latest IE5 standards to dramatically reduce operational energy expenditure and lower corporate carbon footprints.
Establishing global benchmarks in large, medium, high, and low-voltage electric motor manufacturing since 1955.

An in-depth look at emerging global procurement trends, system integration, and safety engineering paradigms.
Global standards, such as the European Ecodesign Directive, mandate minimum efficiency levels for industrial electrical machinery. As a result, the transition from IE3 to IE4 and IE5 (YBX5 and YE5 series) has accelerated. Increased efficiency reduces thermal dissipation requirements within flameproof enclosures, resulting in cooler motor operation and extended bearing lifetimes.
Deploying Medium Voltage motors on variable frequency drives (VFDs) (such as the YVFE3 and YBBP series) introduces electrical stress. High dV/dt rates can degrade winding insulation. LITESIMO designs these motors with Class H insulation, VPI treatment, and isolated bearings on the non-drive end to prevent circulating shaft currents from causing premature bearing failure.
For grain elevators, coal pulverizers, and processing plants, dust explosion-proof motors (such as the YFB3 and YFB4 series) must prevent combustible dust ingress. High-integrity labyrinth seals and high-tensile frame joints isolate electrical components from external dust clouds.
Proper heat rejection is vital for high-power, medium-voltage applications. We offer several custom configurations:
Using high-grade structural steel and ductile cast iron allows our motor frames to withstand internal explosions. Precision machining ensures that our flamepaths comply with ATEX and IECEx specifications, ensuring long-term field reliability.
LITESIMO maintains ISO9001, EU CE, US UL, Russian GOST, and China CCC certifications. We verify every motor against rigorous international standards before dispatch.
How LITESIMO products drive reliability, safety, and efficiency across key global heavy industries.
Refining environments are characterized by volatile vapors (methane, ethylene, hydrogen). LITESIMO provides the YBX3, YBX4, and YBX5 flameproof series to drive compressors, high-pressure pumps, and heat exchanger fans safely within Zone 1 and Zone 2 gas areas.
Methane accumulation and coal dust require explosion-proof machinery. Our YBK3 series flameproof motors are designed for underground coal mines. They drive scraper conveyors, coal cutters, and ventilation fans, featuring high starting torque and thermal overload protection.
Cement mills, SAG mills, and iron mining pulverizers require high starting torque and precise speed control. The TDMK series three-phase synchronous motors are optimized for mine milling, helping operators maintain high power factors and stable grid performance.
Municipal water works and deep drainage systems rely on our high-voltage YKS and YKK induction motors. Equipped with optional water-to-water or air-to-air cooling systems, these motors run continuously in high-humidity settings.
Our heavy-duty Z series large DC motors and modern Z4 series DC motors provide responsive torque profiles and wide speed variation ranges. They are ideal for paper mills, metal extruders, and mine hoists requiring precise control.
