Engineered to deliver exceptional mechanical performance in demanding environments worldwide.
Founded in 1955, Xi’an Lite SIMO Motor Co., Ltd. is a prominent enterprise specializing in the manufacturing of large and medium-sized, high and low voltage AC/DC electric motors, synchronous motors, and highly complex explosion-proof motors within the Chinese mechanical industry.
As a comprehensive supplier, SIMO integrates motor design, mechanical processing, high-precision assembly, mold manufacturing, and professional support services. The company consistently ranks at the top of the industrial sector in China due to its manufacturing capacity, technological capability, and strict quality control systems.
We are dedicated to delivering reliable power solutions that fulfill international safety criteria in hazardous areas.
Understanding international safety standards is essential for implementing electric motors in hazardous environments.
Designed to withstand an internal explosion of a flammable gas or vapor without transmitting the ignition to the surrounding explosive atmosphere. Suitable for Zone 1 and Zone 2 applications.
Focuses on preventing the generation of sparks, arcs, or excessive temperatures during normal operation. This design utilizes high-quality insulation materials and specific tolerances to minimize risk.
Utilizes tight enclosures (IP6X rating) to prevent combustible dusts from entering the motor housing. It regulates surface temperatures to prevent dust layers from igniting in processing plants.

Providing high torque capability for mill drives and steel rolling mills. Delivers consistent speed regulation under varying load conditions.
Our manufacturing processes utilize Vacuum Pressure Impregnation (VPI) systems, applying solventless resin under pressure to ensure void-free insulation structures. This process enhances the motor's dielectric strength, mechanical stability, and resistance to environmental moisture.
Every Ex-certified motor undergoes rigorous flamepath dimensional checks, hydro-static testing of flameproof housings, and type testing before dispatch, verifying mechanical reliability and safety compliance.
Our electric motors provide reliable power in challenging and hazardous operating conditions.
Powering process pumps, cooling fans, and compressors in environments with flammable gases and vapors. Our flameproof (Ex d) motors are designed to operate safely in Zone 1 locations.
Providing durable motors for conveyors, mine ventilation fans, and shearers. Our flameproof mining motors (YBK3 series) are built to resist methane and coal dust environments.
Driving heavy processing equipment, including large ball mills, crushers, and rolling mills. Our TDMK synchronous motors deliver high torque under continuous load.
SIMO motors comply with ISO9001 Quality System standards and hold certifications for international markets, including CE, UL, and GOST.
Key parameters for sourcing industrial electric motors for hazardous locations.
Identify whether the installation requires Zone 0, Zone 1, or Zone 2 equipment. Select the corresponding protection methodology (e.g., Ex d, Ex e, Ex nA) to match local regulatory demands.
Specify the gas ignition temperature threshold (T1 to T6). Ensure the motor's maximum surface temperature remains below the ignition point of gases present in the environment.
Match the required voltage configurations (e.g., 380V, 6KV, 10KV) and frame size specifications (IEC or NEMA). Specify duty cycle requirements, including S1 continuous or S3 intermittent duty.
When operating motors via Variable Frequency Drives (VFDs), ensure they are equipped with insulated bearings or shaft grounding rings to mitigate high-frequency bearing currents.
Confirm the Ingress Protection (IP) rating. Outdoor installations or coastal processing units typically require IP55, IP56, or IP65 ratings to protect against dust and water ingress.
