2-Stage NMRV 63 – 90 Gear Motor

The 2-Stage NMRV 63 – 90 Gear Motor is a gear motor combined from an electric motor, specifically a 3-phase electric motor, and a gearbox, specifically a 2-stage gearbox. This connection multiplies the gear ratio many times compared to the single-stage type, while maintaining stability, robustness, and minimizing vibration during operation.

Overview of 2-Stage NMRV 63 – 90 Gear Motor

Electric Motor Block

• Material: Ribbed extruded aluminum housing for optimal heat dissipation; electrical terminal box equipped with heat-resistant rubber gaskets meeting IP55 protection standards.
• Characteristics: Medium and small power, stable starting torque, low no-load current. Smooth operation and good heat generation control to protect the primary stage oil seal.

2-Stage Gearbox (NMRV 63 + NMRV 90)

• Mechanism: Directly coupling the primary NMRV 63 gear unit to the secondary NMRV 90 gear unit. Right-angle 90-degree shaft redirection, multi-stage speed reduction to achieve an ultra-large total gear ratio for extremely slow output speeds (below 1 rpm).
• Characteristics: Both stages are constructed from monolithic die-cast aluminum housing, creating an ultra-compact structure, enhancing aesthetics, and facilitating multi-directional hanging installation. The worm gear mechanism features a high static self-locking coefficient, preventing free load drift when the machine stops.

Structure of 2-Stage NMRV 63 – 90 Gear Motor

The 2-Stage NMRV 63 – 90 Gear Motor is assembled from a 3-phase electric motor 0.37kW 0.5Hp combined with a 2-stage NMRV gearbox. This connection multiplies the gear ratio many times compared to the single-stage type, while maintaining stability, robustness, and minimizing vibration during operation. The details include:

Electric Motor Structure:

• Stator: Cast from solid copper, which is the inner part of the motor.
• Rotor: Composed of lightweight thin steel laminations, the rotor rotates due to the action generated by the stator.

Gearbox Structure (Specifically the NMRV Gearbox):

• Stage 1 is the NMRV 63 gearbox featuring a sturdy, modern design suitable for continuous industrial working environments.
• Stage 2 is the NMRV 90 gearbox with an outer casing made of cast iron or solid aluminum.

Technical Specifications of 2-Stage NMRV 63 – 90 Gear Motor

The 2-stage NMRV 63 – 90 gear motor is a transmission solution chosen by many units when a large gear ratio is required within a compact structure. Combining two NMRV gearboxes in a direct connection format helps the device produce a low output speed, while enhancing load-bearing capacity and maintaining stability throughout the working process.

Technical Specifications of 3-Phase Electric Motor 0.8kW 1Hp

The 3-phase electric motor 0.8kW 1Hp is manufactured with a sturdy structure, well meeting the requirements for continuous operation in industrial environments. The standard flange mounting style makes connecting to the gearbox unit convenient, ensuring high concentricity during power transmission.

Technical Specifications of NMRV 63 Gearbox

The NMRV 63 gearbox acts as the primary transmission stage, receiving power from the motor and adjusting the rotational speed before moving to the next reduction stage.

Technical Specifications of NMRV 90 Gearbox

In the second transmission stage, the NMRV 90 gearbox continues to reduce speed and increase output torque. This design helps the entire system achieve higher transmission efficiency, especially in applications requiring slow speed and stable pulling force.

Applications of 2-Stage NMRV 63 – 90 Gear Motor

• The product is widely used in industries requiring high stability:
• Conveyor belt systems in manufacturing plants.
• Mixers, agitators, packaging machines, equipment requiring large pulling force.
• Food processing, pharmaceutical, and woodworking production lines.
• Lifting systems, textile pullers, coiling machines, or cutting machines.
• Automation equipment with low speed and large torque requirements.

Guide on Assembling Electric Motor with 2 NMRV Gearboxes

• Step 1: Fit the electric motor tightly to gearbox 1 using sturdy screws.
• Step 2: Insert the intermediate coupling shaft bar into the output shaft hole of gearbox 1.
• Step 3: Bring gearbox 2 close, allowing its input shaft to engage the intermediate coupling shaft bar.
• Step 4: Fix the two gearboxes tightly together by fully tightening the locking screws.

Note: Align the shafts straight, wipe clean any external dust, and tighten the screws evenly.
