2-Stage NMRV 50 – 130 Gear Motor

The 2-Stage NMRV 50 – 130 Gear Motor is a gear motor combined from an electric motor, specifically a 3-phase electric motor, with a gearbox, specifically a 2-stage gearbox, specially used in transmission systems requiring high torque and extremely low output speed. The device delivers an outstanding transmission ratio while maintaining a compact structure and high operational stability.

Overview of the 2-Stage NMRV 50 – 130 Gear Motor

Electric motor block

• Material: The casing is cast from lightweight aluminum alloy, integrated with fine, vertically arranged heat-sink fins to dissipate heat quickly. The electrical wiring terminal box is wrapped with waterproof elastic rubber gaskets meeting the IP55 tight protection standard.
• Characteristics: Optimizes torque at high rev ranges of small motors, helping the primary system operate smoothly, minimizing voltage drop and jolting phenomena during the initial start-up cycle.

2-stage gearbox (NMRV 50 and NMRV 130)

• Function: Directly connects the core of the mini NMRV 50 gearbox to the core of the medium-duty NMRV 130 gearbox. The dual setup bends the power flow at a 90-degree right angle, creating a maximum transmission ratio step to serve movements requiring micro-translational velocity or ultra-slow scanning/rotation.
• Characteristics: The large size disparity between the two stages (50 and 130) provides almost absolute anti-reversal (static self-locking) capability. The outer shell frame is surface-treated for anti-oxidation and coated with heat-cured paint to prevent peeling.

Structure of the 2-Stage NMRV 50 – 130 Gear Motor

The 2-Stage NMRV 50 – 130 Gear Motor is assembled from a 3-phase electric motor 0.55kW 0.75Hp combined with a 2-stage NMRV gearbox. The device easily connects with various electric motors through a standard flange. This makes the installation, maintenance, and replacement process quick, saving time for users. It includes the following details:

Electric motor structure:

• Stator – Stationary part: Consists of pure copper wires wound around the core, offering good conductivity and generating a strong, stable magnetic field.
• Rotor – Rotating part: Consists of technical steel laminations pressed into a block, placed inside the core, moving thanks to the action of the rotating magnetic field.
• Cooling fan: The rear of the motor body is equipped with fan blades to effectively dissipate heat and cool the motor, preventing the equipment from overheating during continuous operation.

Gearbox structure:

• Stage 1 is the NMRV 50 gearbox, designed with a sturdy, modern style suitable for continuous industrial working environments.
• Stage 2 is the NMRV 130 gearbox, designed with an outer shell made of solid cast iron or aluminum.

Specifications of the 2-Stage NMRV 50 – 130 Gear Motor

The 2-Stage NMRV 50 – 130 Gear Motor is composed of a 3-phase electric motor combined with two NMRV gearboxes, creating a transmission set with a large transmission ratio and high torque generation capability. The two-stage reduction design helps the device achieve low output speed, suitable for systems requiring stability and precision during operation.

Specifications of the 3-Phase Electric Motor 0.37kW 0.5Hp

The 3-phase electric motor 0.37kW 0.5Hp features a compact structure, stable working performance, and continuous operation capability. The flange-mounted style makes the connection process with the gearbox quick and convenient.

Specifications of the NMRV 50 Gearbox

The NMRV 50 gearbox serves as the first reduction stage in the transmission assembly, designed with compact dimensions and stable transmission capabilities, contributing to enhancing the reduction efficiency for the entire system.

Specifications of the NMRV 130 Gearbox

The NMRV 130 gearbox plays the role of the second reduction stage, helping to further reduce output speed and increase torque, ensuring stable transmission capacity for continuous working systems.

Applications of the 2-Stage NMRV 50 – 130 Gear Motor

The 2-Stage NMRV 50 – 130 Gear Motor is used in various heavy-duty transmission systems or those requiring very low output speeds, including:

• Heavy-duty conveyor systems and industrial conveyor belts.
• Mixers, presses, and rolling machines in the material industry.
• Wood processing, food, seafood, and pharmaceutical production lines.
• Lifting systems, winches, cable winding machines, and coil cutting machines.
• Automation equipment requiring high torque and high stability.

Instructions for Installing an Electric Motor with 2 NMRV Gearboxes

• Step 1: Assemble the electric motor directly to the first gearbox by tightening the bolts securely.
• Step 2: Attach the intermediate coupling shaft directly into the output shaft hole of the first gearbox.
• Step 3: Fit the input shaft part of the second gearbox so that it completely engages with the intermediate coupling shaft.
• Step 4: Tighten the connecting bolts to join the two gearbox bodies together securely.

Note: Contact surfaces must be clean, shafts must not be misaligned, and bolts should be tightened alternately and evenly.
