The NAMKANG NV181 is a flange-mounted geared motor utilizing the F181 frame size, featuring a 50 mm output shaft and a Vertical Type – V/T configuration. The front flange allows for direct mounting onto machinery, rotary tables, or structures where foot mounting is impractical.
The NV181 is available in power ratings of 2.2 kW, 3.7 kW, 5.5 kW, and 7.5 kW. Depending on the power output, it supports gear ratios from 1/3 to 1/120. The three-phase version can be paired with NK PLUS or HYOSUNG motors; the 2.2 kW single-phase configuration utilizes a SAMIL motor.
Gearbox frame: F181 – frame size 50.
Mounting type: Vertical Type – V/T.
Power range: 2.2–7.5 kW.
Total gear ratio range: 1/3–1/120.
4-pole motor.
Available in single-phase and three-phase configurations depending on power.
Nominal output shaft: Ø50 h6.
Circular flange with 6 mounting holes.
Optional AC-B or DC-B brake motor configurations.
Suitable for industrial machinery requiring direct flange mounting.
The name NV181 is used on MDRIVETECH to distinguish the flange-mounted F181 frame. In NAMKANG technical drawings, the product is designated as Geared Motor F181 Vertical Type (V/T).

The NV181 can be combined with a brake motor for applications requiring quick stops, anti-drift, or load positioning.
For 2.2–3.7 kW versions, the AC-B Brake increases motor length by approximately 100 mm, while the DC-B Brake increases it by approximately 80 mm.
For 5.5–7.5 kW versions, the AC-B Brake increases length by approximately 125 mm, while the DC-B Brake increases it by approximately 100 mm.
Please verify the clearance behind the motor before selecting a brake version.
The NAMKANG NV181 is suitable for:
Agitators and mixers.
Feeders.
Industrial rotary tables.
Screw conveyors.
Packaging machinery.
Positioning mechanisms.
Lifting and handling equipment.
Assembly lines.
Logistics systems.
OEM machinery requiring flange mounting.
The 2.2–3.7 kW versions are suitable for mechanisms requiring high gear ratios and low speeds. The 5.5–7.5 kW versions are suitable for equipment requiring higher power and medium output speeds.
MDRIVETECH distributes NAMKANG geared motor lines and provides support for selecting the NV181 based on the correct power, gear ratio, power supply, and mounting dimensions.
Customers needing to check output speed, torque, shaft diameter, flange, or brake motor options can send the model and images of the product currently in use for configuration matching.
