The NH181 can be paired with a brake motor for applications requiring quick stops or load holding.
For 2.2–3.7 kW versions, the AC-B Brake increases the 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 the length by approximately 125 mm, while the DC-B Brake increases it by approximately 100 mm.
Installation space should be verified before replacing a standard motor with a brake version.
The NAMKANG NH181 is suitable for:
Industrial conveyors.
Feeders.
Packaging machines.
Screw conveyors.
Agitators and mixers.
Winches.
Lifting and handling equipment.
Assembly lines.
Logistics systems.
OEM machinery.
The 2.2–3.7 kW versions are suitable for mechanisms requiring low speeds and high gear ratios. The 5.5–7.5 kW versions are better suited for applications requiring high power and medium output speeds.
MDRIVETECH distributes NAMKANG geared motor lines and provides support for selecting the NH181 based on the correct power, gear ratio, power supply, and mounting dimensions.
Customers needing to check output speed, torque, shaft, base, or brake motor options can send the model and photos of the currently used product for configuration matching.
