Shin Myung SM-15P-1000 Air Motor

SHIN MYUNG SM-15P-1000 Air Motor (15 PS, 1000 RPM)

The SHIN MYUNG SM-15P-1000 Air Motor is a heavy duty high capacity pneumatic piston motor for harsh marine and offshore applications. It is an industrial motor developed by Shin Myung Tech Co., Ltd., South Korea’s premier pneumatic expert, delivering 15 PS (metric horsepower) of power at the rated speed of 1000 RPM.

Unlike conventional electric motors, which are dangerous because of severe sparking and overheat when stalled continuously, the SM-15P-1000 uses only compressed air. Its rugged radial piston architecture affords huge starting torque, stepless variable speed control and fundamentally safe, explosion-proof operation. This makes it the preferred mechanical choice in commercial fleets worldwide for heavy-lift winches, mooring systems, and pneumatic hoists.

Key Features

1. 100% Explosion-proof performance: Fully mechanical operation, no electrical components, hence no sparks in ATEX zones, pump rooms and volatile atmospheres.
2. Exceptional Starting Torque: Its internal radial piston design means it gives tremendous torque production instantly from standstill, allowing smooth starts under heavy loads.
3. Stepless variable speed control: Adjust rotational speed and directional torque on the go, with ease, by modulating the air supply with a standard regulator or hand control valve.
4. Cool Running & Stall Protection: The expansion of compressed air naturally cools the motor during continuous running. It can be delayed indefinitely under peak loads without overheating or burning out.
5. Marine-Grade Durability. Constructed with a durable, corrosion resistant cast alloy casing and reinforced internal steel parts to withstand salt spray, high humidity and heavy vibrations.

Compatibility & System Integration

• Air Supply Line: This is to be connected to ship main working air or industrial compressor lines at normal working pressures (6 to 9 kg/cm²).
• Control Configuration: Can be combined with manual hand lever control modules, pneumatic remote control lines or fail-safe mechanical brake modules.
• Mounting Interface: Fixed base/foot mount configuration for high mechanical torque without flexing.

Maintenance Guide:

1. Prioritize FRL Units: Air motors are remarkably reliable, but their biggest enemy is moisture and dry friction. Always install a high-capacity Filter-Regulator-Lubricator (FRL) unit right before the air inlet. For a 15 PS motor, set the lubricator to feed a consistent, fine mist of ISO VG 32 pneumatic tool oil to prevent vane/piston scuffing.
2. Exhaust Line Management: Because the SM-15P-1000 runs on high volume expansions, ensure your exhaust lines are completely free from obstructions and that the silencer is clean. A restricted exhaust creates backpressure, drastically dropping your motor’s RPM and mechanical efficiency.
3. Post-Stall Checks: While this air motor is built to safely stall without damaging internal parts, an unexpected stall usually indicates a mechanical jam in your winch or davit gear train. If it stalls, shut down the air line immediately, check your load line, and ensure your mechanical brake module is fully disengaging before re-applying air pressure.
