2-Stage NMRV 50 – 110 Gear Motor

The 2-Stage NMRV 50 – 110 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 product features two different sizes, allowing the equipment to achieve strong pulling force, very low output speed, and stable operation even under heavy-load conditions or continuous working.

Overview of the 2-Stage NMRV 50 – 110 Gear Motor

Electric Motor Assembly

• Material: Motor housing made from extruded cast aluminum, integrated with vertical cooling ribs to increase the contact area with the air. The terminal box is equipped with a sealed rubber waterproof gasket, achieving an IP55 protection rating against fine dust and low-pressure water jets.
• Characteristics: Optimized winding design for starting torque range at high speed, helping the primary system operate smoothly. The motor runs quietly, with low no-load current and minimizes local heat generation during long cycles.

2-Stage Gearbox (NMRV 50 + NMRV 110)

• Function: Directly couples the small NMRV 50 gearbox (primary stage) into the core of the mid-size NMRV 110 gearbox (secondary stage). This mechanism redirects the power flow by a 90-degree right angle, driving the total gear ratio up to a massive level to achieve ultra-slow output speeds with high pulling force.
• Characteristics: The 50 – 110 combination provides a very compact installation structure, fitting closely to the equipment frame, saving more space than the 130 or 150 series. Extremely high mechanical self-locking coefficient, effectively preventing free load drift when power is suddenly cut off.

Structure of the 2-Stage NMRV 50 – 110 Gear Motor

The 2-Stage NMRV 50 – 110 Gear Motor is assembled from a 3-phase electric motor 2.2kW 3Hp combined with a 2-stage NMRV gearbox (NMRV 2-stage gearbox). The equipment easily integrates with various types of electric motors through standard flanges. This ensures that the installation, maintenance, and replacement processes take place quickly, saving time for users. The details are as follows:

Electric Motor Structure:

• Stator – Stationary part: Pure copper wires wound around the core, offering good electrical conductivity and generating a strong, stable magnetic field.
• Rotor – Rotating part: Consists of laminated electrical steel sheets pressed into a block, placed inside the core, moving under the influence of the rotating magnetic field.
• Cooling fan: Equipped at the rear of the motor body 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 110 gearbox, featuring an outer shell made of solid cast iron or aluminum.

Technical Specifications of the 2-Stage NMRV 50 – 110 Gear Motor

The 2-Stage NMRV 50 – 110 Gear Motor is a drive system utilizing two worm gearboxes connected in series, helping to create a high gear ratio and low output speed. Thanks to the two-stage reduction structure, the product delivers efficient torque increase while maintaining stability throughout operation.

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

The 3-phase electric motor 0.37kW 0.5Hp is designed with criteria of compactness, energy saving, and easy installation. Sturdy construction along with IP55 protection rating helps the motor operate stably in various working environments.

Technical Specifications of the NMRV 50 Gearbox

The NMRV 50 gearbox is positioned as the primary reduction stage, responsible for receiving power from the motor and transmitting drive to the second-stage gearbox with stable efficiency.

Technical Specifications of the NMRV 110 Gearbox

The NMRV 110 gearbox is the second reduction stage in the system, helping to complete the reduction process and generate greater torque at the output, well meeting transmission requirements that need high gear ratios.

Applications of the 2-Stage NMRV 50 – 110 Gear Motor

The NMRV 50 – 110 gear motor series is widely applied in various production fields, especially systems requiring high torque and low speed:

• Industrial conveyors, packaging lines, and cargo transportation systems.
• Mixers, presses, and grinders in the food and material industries.
• Cable winches, canvas pullers, and lifting equipment.
• Wood processing, pharmaceutical, and aquaculture production lines.
• Automation systems requiring durable, stable operation over long periods.

Guide on Installing an Electric Motor with 2 NMRV Gearboxes

• Step 1: Fit the electric motor onto the flange of the first gearbox and tighten the screws securely.
• Step 2: Insert the intermediate coupling shaft straight into the output shaft hole of the first gearbox.
• Step 3: Take the second gearbox, insert its input shaft part into the remaining end of the intermediate coupling shaft.
• Step 4: Use screws to fasten the two gearboxes tightly together to avoid any backlash.

Note: Clean the parts thoroughly before working, align the shafts straight, and tighten the screws evenly at all corners.

Guide on Installing an Electric Motor with 2 NMRV Gearboxes

• Step 1: Fit the electric motor onto the first gearbox and tighten the screws securely.
• Step 2: Attach one end of the intermediate coupling shaft into the output shaft hole on the first gearbox.
• Step 3: Take the second gearbox, insert its input shaft part into the remaining end of the intermediate coupling shaft.
• Step 4: Use screws to fasten the two gearboxes tightly together to secure them into a single unit.

Note: Align the shafts straight, clean the contact surfaces before assembly, and tighten the screws evenly.
