In the world of hydraulic systems, the stability and efficiency of power output directly determine the ultimate performance of equipment. Faced with the severe challenges of oil infiltration, high temperature and high pressure, and extreme working conditions, WONDER motors have the core competitiveness of oil resistant sealing, high power density, and professional adaptability, providing strong power support for hydraulic pump stations, lifting equipment, and power systems. Whether it is the surging operation of construction machinery or the precise control of precision hydraulic stations, WONDER always takes technological breakthroughs as the industry benchmark, helping enterprises unlock more efficient and reliable hydraulic drive solutions. The specific application advantages are as follows:

1. Oil resistant environment and high sealing design: The hydraulic system has been immersed in oil for a long time. The WONDER NMS71/80 oil immersed motor is specially developed for such scenarios, using IP00 protection level and fully enclosed structure, directly immersed in hydraulic oil for operation. The continuous cooling of the oil significantly improves the heat dissipation efficiency, and the output power is increased by more than 20% compared to standard motors of the same specifications. Stainless steel shaft, ball bearings, and F-grade insulation design ensure long-term stable operation of the motor in high-temperature oil (≤ 60 ℃).

2. Compact structure and high power density:

-Direct connection adaptability: The NMS series motor supports direct connection installation with hydraulic pumps, with a compact design that saves space and is suitable for equipment such as car lifts and hydraulic presses;

-Strong load capacity: Under short-term working conditions (S2), it can withstand frequent start stop and instantaneous overload, meeting the high dynamic response requirements of hydraulic systems.

3. Adaptability to extreme working conditions:

-Corrosion resistance and leakage prevention: The casing is treated with electrophoretic technology, matched with stainless steel fasteners and flame-retardant blades, to resist hydraulic oil chemical corrosion and dust invasion;

-Wide temperature operation: equipped with NSK high and low temperature bearings and wide temperature grease, suitable for environments ranging from -20 ℃ to 40 ℃, ensuring reliability under extreme cold or high temperature conditions.

4. Core application scenarios:

-Hydraulic pump drive: NMS series motors are compatible with gear pumps and plunger pumps, providing stable power for construction machinery such as excavators and loaders;

-Lifting equipment: driving car lifts, hydraulic lifting platforms, with oil resistant cooling characteristics to avoid overheating and shutdown;

-Industrial hydraulic station: The RYS series reduction motor is paired with a helical gear reducer to achieve precise speed regulation and high torque output of the hydraulic system;

-Special hydraulic equipment: Customized motors are suitable for ship hydraulic servos and metallurgical presses to meet the needs of high-pressure and high-frequency operations.

5. Customized services and energy efficiency upgrades:

WONDER supports deep customization of power (0.25-7.5kW), installation method (flange/foot), and cooling method (oil cooling/air cooling). For example, mining hydraulic breakers can be customized with reinforced shafts and anti vibration structures, while offshore platform hydraulic systems use C5 grade anti-corrosion coatings and stainless steel casings to extend equipment life.

From hydraulic breakers deep in mines to hydraulic servos for ocean going vessels, the presence of WONDER motors is active in every scene that requires ultimate power. Through oil resistant environment adaptation, compact structural design, and customized services throughout the entire lifecycle, we have created a one-stop solution for the hydraulic industry from power drive to system integration, helping enterprises achieve comprehensive goals of energy conservation, long-term operation, and cost optimization. In the future, WONDER will continue to deepen its technological innovation and work with global partners to promote the hydraulic industry towards intelligence and greenness.
