Engineered for hazardous locations, mining grids, and heavy duty industrial drives.
Founded in 1955, Xi'an Lite SIMO Motor Co., Ltd is an electric manufacturing enterprise specializing in the production of large, medium, and small-sized, high and low voltage AC/DC motors, synchronous, and explosion-proof motors within the global mechanical industry. SIMO stands out as a comprehensive design, precision manufacturing, metalworking, tooling, and system service supplier.
As a key cornerstone of industrial growth, SIMO continually leads the market, ranking at the forefront of China's motor industry in manufacturing scale, operational capability, and technical advancement.
Bridging heavy infrastructure demand with custom-engineered induction technologies.
Demands explosion-proof motors (YB3, YBX4) that comply with ATEX and IECEx specifications, ensuring absolute containment of internal ignition sources in explosive environments.
Requires robust asynchronous motors with high starting torque (YR, YRKK slip ring series) to drive ball mills, heavy conveyors, and crushers under high mechanical stress.
Needs continuous duty high-voltage pumps powered by YKS water-cooled systems, maximizing operational runtime and thermal management in humid, enclosed pump rooms.
Uncompromising construction quality and material selection designed to outlast standard motors.
A squirrel cage induction motor (also known as a squirrel motor) relies on electromagnetic induction, where the stator windings are supplied with alternating current (AC), creating a rotating magnetic field that induces currents in the short-circuited bars of the rotor. SIMO leverages optimized slot designs, low-loss electrical steel laminations, and precision balance factors to provide reliable performance. Our power ranges span from 0.35kW to 25,000kW, with voltages including 380V, 6kV, 10kV, and customized variations.
By implementing computer-aided electromagnetic designs, SIMO optimizes the rotor bars' cross-sectional area, minimizing stator copper loss and winding temperatures. Class F insulation, combined with VPI (Vacuum Pressure Impregnation) varnishing processes, guarantees thermal reserves (Class B temperature rise limit), high dielectric strength, and resistance to environmental moisture.
Developing green, high-efficiency, and intelligent powertrain systems for industry 4.0.
We are transitioning our core low-voltage asynchronous range (YE5 series) into production layouts, reducing heat output and cutting energy losses by up to 20% compared to standard IE3 motors.
Integrating built-in vibration, bearing temperature (Pt100 RTDs), and winding temperature sensors that connect directly to cloud-based monitoring suites to help prevent unplanned downtime.
Developing permanent magnet-assisted synchronous motors (PMSM) for variable speed drives (VFD), optimizing partial-load efficiency in complex ventilation and pumping loops.
Compliant with international standards to ensure smooth integration into overseas engineering structures.
SIMO has passed ISO9001 Quality System Certification, European Union "CE", United States "UL", and Russian Federation "GOST". This ensures compliance with structural and electrical safety standards across multiple major industrial regions.
Deep-dive answers to common engineering, procurement, and deployment questions.
High-voltage slip-ring, high-torque synchronous, and legacy DC machinery for direct component matching.
