Engineered to meet JISC (Japanese Industrial Standards Committee) requirements and optimized for replacement and retrofitting projects across Japan's leading manufacturing hubs.
Japan's industrial manufacturing ecosystem is globally renowned for its adherence to precision, the Monozukuri philosophy, and extremely tight efficiency regulations. Across heavy industries in Keihin, Hanshin, and Kitakyushu, manufacturing systems heavily rely on massive drive systems, specifically DC motors, which provide unmatched starting torque, precise speed regulation, and structural robustness.
In recent years, the Japanese industrial market has faced unique challenges. The aging of infrastructure installed during Japan's rapid economic expansion means thousands of legacy motors in steel mills, cement factories, paper mills, and municipal water works are reaching their end-of-life cycle. Converting these massive installations directly to AC variable frequency drives requires costly structural alterations, grid modifications, and extended downtime.
Consequently, high-quality, custom-engineered replacement DC motors are in massive demand. By partnering with leading suppliers who can match exact physical mounting configurations, shaft tapers, electrical voltages, and protection ratings, Japanese procurement officers achieve seamless retrofitting with minimal downtime.

Reformed into a limited liability company from a state-owned factory to drive market-centric innovations.
SIMO Motor Group established, organizing resources and core competencies across 14 specialized subsidiaries.
Moved to a state-of-the-art, high-tech, and advanced new manufacturing facility to deploy modern automated production tooling.
Changed name to Tech Full Simo Motor, aligning corporate strategy with smart technologies and global distribution.
Still on the way to be one of the best motor manufacturers, expanding footprint inside East Asian markets, especially Japan.
Our industrial research focuses on three major pathways: increasing specific power density, enhancing structural reliability through custom thermodynamics, and incorporating predictive sensor networks for IoT integrations.
By incorporating low-loss silicon steel laminations and advanced rotor-stator pole slot design, SIMO DC motors minimize core losses and maximize peak torque profiles under intermittent industrial loads.
Featuring Class H vacuum-pressure impregnation (VPI) insulation, our DC motors operate reliably under heavy thermal fluctuations, protecting against carbon dust build-up and winding flashovers.
Optional integrations of PT100 temperature sensors in windings/bearings, vibration detectors, and brush wear alert transmitters directly interface with factory SCADA platforms.

To provide stable, premium motor supplies to high-demanding markets like Japan, Xi'an Lite SIMO Motor Co., Ltd leverages China's ultra-efficient industrial manufacturing matrix. Located in Xi’an, the historic industrial heartland of Western China, SIMO operates 3 major manufacturing factories and 1 subsidiary factory. The factory footprint houses a registered capital of 21.5 million RMB and maintains fixed assets worth over 380 million RMB.
Our facility is equipped with over 1,172 sets of advanced equipment. This includes high-precision CNC boring machines, automated winding and forming machines, vacuum pressure impregnation chambers, dynamic balancing machines, and advanced digital motor test stations.
We source 100% pure electrolytic copper wire and grade-A cold-rolled non-oriented silicon steel to minimize electromagnetic loss and operational thermal dissipation.
Modern robotics and automated tooling ensure high consistency in rotor balancing and stator winding configurations, virtually eliminating manufacturing deviations.
Every motor is subjected to comprehensive testing before shipment, measuring load capacity, temperature rise, vibration signature, and dielectric strength.
For Japanese engineers and procurement departments, certification compliance is the ultimate foundation of reliability. SIMO Motor has systematically passed ISO9001 Quality System Certification, the European Union's "CE", the United States' "UL", and the Russian "GOST". Electric motors are widely applied in electricity, coal, petroleum, mining, metallurgy, railway, transportation, chemical industry, agriculture, water economy, aviation, navigation and high technologies and other areas in China and abroad.
Solving engineering dilemmas, addressing standards compliance, and structuring the procurement roadmap for Simo DC Drives.
Converting a heavy industrial drive (such as a steel mill rolling stand or a paper mill extruder) from DC to AC variable frequency drives requires not just motor replacement, but massive capital expenditure. This includes rebuilding mechanical foundations, installing highly complex and expensive AC VFD cabinets, changing input transformers, and modifying structural mechanical gearboxes. Retrofitting with a drop-in custom SIMO DC motor that replicates the original mounting footprint, shaft tapers, and torque characteristics saves substantial initial costs and cuts operational downtime by up to 80%.
Yes. Our R&D team consists of over 260 technical engineers, including 21 senior engineers and 15 expert engineers. We can customize the output shaft dimensions (cylindrical or tapered), keyways, mounting foot dimensions, and center heights. Prior to manufacturing, we issue detailed CAD and 3D mechanical drawings for verification by the Japanese engineering team.
Our motors are designed according to international IEC standards, which have high alignment with JISC (Japanese Industrial Standards Committee) specifications. We perform structural insulation tests, vibration testing to ISO 1940 balancing standards, and heat run tests. Certified explosion-proof series motors can be configured to comply with the necessary hazardous zone classifications required in Japanese petrochemical and chemical processing plants.
For a comprehensive proposal, please provide: Rated Power (kW), Rated Voltage (V) for both armature and field windings, Base Speed (RPM) and Maximum Speed (RPM) range, Cooling method (e.g., IC06 force-ventilated, IC37 duct-ventilated, or IC86W water-cooled), Mounting configuration (IMB3, IM3001, etc.), Protection Rating (IP23, IP44, IP54), and drawings of the existing motor's shaft and mounting feet.
