Examine our high-performance heavy-duty industrial electric motors engineered to comply with ISO9001, CE, UL, and GOST technical criteria.
The modern global industrial complex is undergoing an unprecedented energy transition. Heavy rotating machinery, particularly motors and generators, forms the absolute backbone of this paradigm shift. From water desalination projects in the Middle East to deep-shaft mineral extraction in South America, and high-performance petrochemical refining in Europe, the demand for high-efficiency, reliable, and specialized mechanical-electrical powertrains is at an all-time high.
Global regulatory frameworks, such as the European Minimum Energy Performance Standards (MEPS) and corresponding IEEE/IEC mandates, are pushing industrial enterprises away from obsolete energy-intensive machinery. The transition to premium efficiency (IE3, IE4, and IE5) standards is no longer just a voluntary environmental target—it is an economic imperative. Modern processing plants are highly focused on minimizing Total Cost of Ownership (TCO), of which energy consumption constitutes over 90% during a motor's operational lifespan.

Our design, manufacturing, and diagnostic scope encompasses 34 major series, over 1,800 varieties, and 19,500 individual custom specifications ranging from 0.35kW to 25,000 kW.
Our YX, YXKK, and YXKS high-efficiency, high-voltage three-phase asynchronous motors represent peak configuration flexibility. Operating across 6kV and 10kV configurations, these motors rely on advanced CAD and electromagnetic simulation algorithms to optimize flux density and thermal convection pathways. For applications requiring exceptional starting torque, our slip-ring wound rotor YR, YRKK, and YRKS high-voltage systems deliver highly controlled acceleration curves under high load constraints.
Engineered to minimize industrial carbon footprints and power utility costs, the YE3, YE4, and YE5 series feature highly refined stator winding topologies, high-grade silicon steel laminations, and optimized cooling fans. When combined with our variable frequency drive (VFD) options like the YVFE3, YVFE4, and YVFE5 series, these motors run at optimum efficiency even under fractional loads, reducing magnetic losses and operating temperature anomalies.
For explosive dust and volatile gas zones, our flameproof YBX3, YBX4, and YBX5 series, together with YBK3 (underground coal mining) and YFB3 (dust explosion protection) lines, guarantee maximum structural integrity. Features include flameproof enclosure joints, high-integrity terminal boxes, spark-proof fans, and specialized internal winding temp monitoring (PT100 RTDs) to prevent ignition risks in Zone 1, Zone 2, Zone 21, and Zone 22 environments.
The T, TD, TK, and TDMK series synchronous motors are specifically designed for low-speed, high-power grinding, milling, and crushing applications. Offering precise power-factor correction and transient load stability, they represent the gold standard in mineral and ore processing. Similarly, the TFW large-size synchronous generators (ranging from 350kW up to 5000kW) ensure resilient power generation for regional microgrids and critical backup systems.
In heavy metallurgy, rubber extrusion, and paper manufacturing, dynamic and precise torque response across zero-speed and field-weakening bands is non-negotiable. Our Z2, Z4, and Z series large DC motors incorporate fully laminated stators, heavy-duty commutators, and advanced brush gear arrays. Designed to interface seamlessly with modern digital DC converters, they deliver reliable torque and velocity control under demanding variable cycles.
To protect large high-voltage motors from severe voltage drops and excessive starting current spikes, our custom High Voltage Soft Start Cabinets represent an optimal electrical control system. These cabinets protect both the mechanical transmission system and the upstream distribution grid, incorporating thyristor-based soft starting, digital parameter diagnostics, and real-time bypass protection.
How our customized motor-generator solutions solve engineering problems, optimize energy efficiency, and maintain system stability globally.
Deep underground mining operations demand motors capable of running reliably under high shock loads, dust ingress, and high humidity. In milling applications (e.g., ball mills and SAG mills), our TDMK synchronous motors deliver high starting torque and precise speed regulation, while operating with power factor correction to lower total electrical load demands on regional mining substations.
In gas treatment facilities and petroleum refineries, high-efficiency explosion-proof motors (such as the YBX4 and YFB3 series) drive large centrifugal compressors, blowers, and high-pressure fluid transfer pumps. Our flameproof enclosures are designed to contain internal explosions without risking ignition of the surrounding atmosphere, ensuring continuous plant uptime.
Large-scale water supply systems, flood-prevention pumping stations, and agricultural irrigation networks rely on our YKS high-voltage induction motors to run high-capacity vertical and horizontal pumps. Our water-to-air cooling (IC81W) and air-to-air cooling (IC611) systems ensure effective thermal management, minimizing auxiliary cooling costs and footprint size.
Steel rolling mills require precise, dynamic speed-torque control under sudden load changes. Our Z and Z4 DC motors, engineered with laminated stator frames and robust commutators, deliver high dynamic performance. This ensures consistent steel gauge thickness during high-speed rolling and processing cycles.
The future of heavy rotating machinery is defined by digital intelligence, ultra-efficiency, and advanced materials science. Our engineering teams are working on integrating next-generation systems across several key technology areas:
We design and build all SIMO electric motors and generators with circular economy principles in mind. From using recyclable copper and steel to optimizing raw material consumption in our production facilities, we focus on minimizing environmental impact throughout each product's lifecycle.

YKS, YXKK, and YRKK are series of high-voltage motors designed for different cooling and starting requirements. YKS motors feature water-to-air cooling (IC81W), offering a compact design for sites with cooling water systems. YXKK motors use air-to-air heat exchangers (IC611), making them suitable for environments with limited water resources. YRKK motors are wound rotor slip-ring systems that allow for controlled resistance during startup, delivering high starting torque with low starting currents.
IE5 ultra-premium efficiency motors have lower energy losses than IE3 and IE4 motors. In high-duty cycle applications, upgrading to IE5 can reduce energy consumption by up to 3% to 5%. This lowers operating costs, offsets initial capital expenses, and helps plants meet strict environmental requirements and carbon emission standards.
The YBK3 series uses a flameproof design (Ex d I Mb) built to withstand the pressure of internal methane or coal dust explosions without spreading the flame to the surrounding atmosphere. These motors feature robust cast-iron frames, spark-resistant fans, and highly sealed terminal connections, making them suitable for underground mining machinery.
TDMK series synchronous motors are specifically designed for low-speed, high-power grinding mills (such as ball mills, rod mills, and SAG mills) used in mining operations. They run at a constant synchronous speed regardless of load variations and can operate with a leading power factor, helping improve the overall power factor of the mining facility's electrical grid.
High-voltage motors can draw startup currents up to 6-8 times their rated current, causing voltage drops and mechanical stress on shafts and couplings. A soft start cabinet regulates stator voltage using thyristor control, allowing for a smooth acceleration ramp. This protects winding insulation, extends bearing life, and prevents voltage fluctuations in the upstream power distribution system.
