SRPM112H4W7.5 96% High Efficiency Water Cooled 7.5kw 18000rpm Electric Motor

Product Overview

Engineered for intense industrial demands, the SRPM112H4W7.5 is a 7.5KW 18000rpm permanent magnet electric motor that redefines operational stability and precision. Crafted with a sleek, metallic cylindrical housing measuring L282mm * Φ206mm, this motor feels exceptionally dense and solid, reflecting its superior power density and robust internal architecture. When integrated into your machinery, it operates with a smooth, low-hum acoustic profile, a direct result of rigorous high-speed dynamic balancing and advanced rotor optimization that strictly controls NVH (Noise, Vibration, and Harshness) levels. By utilizing high-performance rare earth permanent magnet materials and precision high-speed bearings, it maintains absolute mechanical stability even when pushed to its 18000rpm limit. The active water cooling circuit ensures the exterior remains remarkably cool to the touch during continuous operation, drastically lowering thermal degradation risks. Ultimately, this unit is strategically designed to lower your Total Cost of Ownership (TCO) by reducing spatial footprint, minimizing routine maintenance intervals, and delivering relentless power to advanced fluid control and compression systems.

Key Product Features

96% Industry-Leading Energy Efficiency

Operating at a remarkable 96% energy efficiency threshold, this motor directly translates into measurable electrical savings for large-scale facilities. By minimizing energy loss during continuous duty cycles, it helps facility managers achieve stringent emission reduction targets while stabilizing daily operational expenditures. The highly optimized magnetic circuit design ensures that maximum electrical input is converted into physical kinetic energy.

Reliable Water Cooling System

Thermal management is handled by a sophisticated internal water cooling labyrinth. As fluid circulates through the precision-machined channels, it rapidly absorbs and dissipates the intense core heat generated during 18000rpm operations. This active temperature regulation keeps the motor running within optimal thermal limits, preventing insulation breakdown and ensuring consistent torque delivery without the loud ambient noise typical of traditional fan-cooled alternatives.

H-Class Isolation for Enhanced Safety

Built with premium H-class insulation materials, the internal copper windings and dielectric barriers are rated to withstand extreme thermal spikes. This superior insulation shields the motor against electrical faults in fluctuating power environments, securing the safety of the wider electrical grid and protecting your valuable connected machinery from unexpected short circuits.

Industrial-Grade Protection & Durability

Engineered to meet strict ingress protection standards (such as IP65/IP67), the motor enclosure is hermetically sealed against penetrating dust and pressurized moisture. Whether deployed in damp processing plants or particulate-heavy manufacturing floors, the internal components remain pristine, ensuring long-term durability in the most complex and unforgiving industrial environments.

Precision Drive Compatibility

Equipped with a highly accurate position signal resolver, the motor pairs perfectly with mainstream inverters and variable frequency drives (VFDs). This allows operators to achieve pinpoint closed-loop control over both speed and torque, ensuring exact operational pacing for sensitive and highly calibrated industrial processes.

Technical Specifications

Evaluating the exact technical parameters is crucial for ensuring proper integration into your existing infrastructure. The specifications detailed below outline the core mechanical and electrical characteristics of the SRPM112H4W7.5 model. Operating within a 380-440V AC voltage range, it delivers a consistent 4 N.m of torque at an ultra-fast 18000rpm. The compact physical dimensions combined with a 4-pole configuration and H-class insulation make it a highly specific component for demanding environments. Please review the data sheet below to verify compatibility with your power supply and mechanical mounting constraints.

Application Scenarios

Hydrogen Oxygen Air Compressors

In the production and handling of industrial gases, the motor delivers the relentless, stable torque required to drive heavy-duty compressor blocks. Its spark-free permanent magnet architecture and highly stable thermal profile provide a secure driving force for compressing volatile hydrogen and oxygen mixtures, ensuring continuous throughput without the risk of stalling under pressure.

Hydrogen Circulating Systems

Modern fuel cell networks rely on uninterrupted, precisely metered gas flow. This motor powers hydrogen circulating pumps with extreme accuracy, utilizing its resolver feedback to adjust speeds dynamically based on real-time system pressure demands. Furthermore, its exceptionally low vibration output protects sensitive adjacent piping and delicate valves from mechanical fatigue over years of operation.

High-Speed Turbines, Fans & Centrifugal Compressors

The 18000rpm capability is perfectly matched for direct-drive centrifugal applications. By eliminating the need for bulky and maintenance-heavy gearboxes, the motor reduces mechanical transmission losses and significantly shrinks the physical footprint of the equipment. It spins up heavy turbine impellers swiftly, pushing massive volumes of air or fluid with unwavering reliability.
