Explore the core heavy-duty motor line-up engineered to drive heavy hydraulic pumps and large industrial fluid systems. Designed for maximum torque density and exceptional reliability under continuous load.
In modern heavy industries, fluid power systems and electric motors are not separate technologies; they are components of a highly integrated mechanical ecosystem. High-performance industrial hydraulic motors, known for delivering immense torque at low speeds, require a continuous, highly reliable high-power fluid source. This source is driven by robust, high-voltage electric motors. In large-scale operations like mining, marine exploration, metallurgical processing, and chemical production, the synchronization between electric prime movers and hydraulic pump-motor systems defines operational efficiency.
Globally, industrial operators are moving away from traditional mechanical transmissions toward electro-hydraulic powertrains. This shift leverages the infinite speed variability of hydraulic systems combined with the efficiency, control, and intelligence of modern electric motors. China's manufacturing sector has emerged at the forefront of this industrial transformation. It offers high-precision hydraulic motors alongside high-efficiency AC/DC electric motors that supply the mechanical energy driving these massive fluid circuits.
Xi’an Lite SIMO Motor Co., Ltd stands as a titan in the Chinese mechanical and electrical engineering landscape. Specializing in the manufacturing of large/medium-sized, high/low voltage AC motors, DC motors, synchronous motors, and explosion-proof motors, SIMO has established itself as a comprehensive engineering partner.
With integrated capacities in motor design, precision mechanical processing, mold fabrication, assembly, and automated testing, the company ranks at the very top of China’s motor manufacturing industry. By providing high-power, high-durability electric motors that serve as the prime movers for massive hydraulic pump stations, SIMO supports the foundations of global industrial heavy drive infrastructure.
For over six decades, our group has evolved from a state-owned regional factory into one of the world's most trusted manufacturers of heavy industrial drive systems.

Heavy industrial environments require mechanical solutions that withstand high dust levels, extreme vibration, wide temperature variations, and corrosive atmospheres. In modern industrial operations, high-performance electric motors drive the hydraulic pumps that feed hydraulic fluid to heavy radial piston motors, axial piston motors, and high-torque swing drives.
In deep underground and open-cast mines, dust explosion-proof three-phase asynchronous motors (such as the YBX4 and YBX5 lines) drive high-pressure hydraulic pumps. These pumps power heavy-duty hydraulic motors in conveyor belts, shearers, and continuous miners, ensuring safety in areas filled with methane and coal dust.
Offshore drilling platforms and marine cargo ships depend on hydraulic winches, deck cranes, and steering gears. High-voltage water-cooled motors (like the YKS series) supply continuous power to the primary hydraulic power units (HPUs), running reliably under saltwater exposure and high humidity.
Steel mills rely on large DC motors (such as the Z4 and Z series) and high-voltage wound rotor motors (YR/YRKK) to handle high-torque rolling mills and furnace tilting devices. The precise speed adjustment of these motors is critical for regulating high-pressure hydraulic cylinders and loopers.
The global industrial landscape demands speed and flexibility. China's industrial manufacturing ecosystem provides competitive advantages in supply chain integration, raw material access, and logistics efficiency. At our Xi'an manufacturing complex, the proximity of casting foundries, electrical steel laminators, copper wire manufacturers, and high-tech machining facilities allows for short production lead times.
Our factory houses more than 1,172 sets of advanced equipment. These facilities enable us to process massive components in-house, maintaining complete quality control from the initial frame casting to final rotor balancing. This vertical integration reduces the risk of global logistics bottlenecks, ensuring that heavy industries receive high-capacity motors and power packs on schedule.
The industrial drive landscape is evolving toward smarter, more integrated systems. The traditional boundary between electric motors and hydraulic pumps is blurring as smart technologies emerge.
Our engineering team focuses on three key technological areas:
As environmental standards tighten worldwide, energy efficiency has become a critical operational requirement. Our YE5 series three-phase motors meet the strict IE5 efficiency standards, significantly reducing energy loss. When paired with variable frequency drives (VFDs), these motors adjust output in real-time to match the system's hydraulic demand, preventing thermal energy loss in the hydraulic fluid.
Modern heavy-duty motors are equipped with temperature detectors (PT100), vibration sensors, and oil-mist detectors. By integrating these sensors with local control units, plants can implement predictive maintenance. Algorithms analyze operational data to flag anomalies like bearing wear or rotor misalignment before they cause system failures, avoiding costly unplanned downtime.
The next step in powertrain design is the direct coupling of high-speed electric rotors with hydraulic pump mechanisms inside a single enclosure. This integration removes external couplings, reduces noise levels, prevents external fluid leaks, and increases the overall power density of the system.
Industrial operations require strict compliance with safety, environmental, and engineering standards. To support global industries, all motors and drive assemblies are manufactured and certified under strict international protocols.
SIMO has passed ISO9001 Quality System Certification, the European Union's "CE" certification, the United States' "UL" safety listing, and the Russian Federation's "GOST" standard. This ensures seamless integration into regulatory frameworks worldwide.
We also provide localized engineering and aftermarket support across Europe, the Americas, and the Asia-Pacific region. Our services include commission support, custom shaft modifications, localized soft-start cabinet installations, and rapid spare parts supply.
