NMRV 2-Stage Gear Motor 90 – 110

The NMRV 2-Stage Gear Motor 90 – 110 is a gear motor line combined from an electric motor, specifically a 3-phase electric motor, with a gearbox, specifically a 2-stage gearbox. It is widely used in industrial zones, industrial parks, and factories.

Overview of NMRV 2-Stage Gear Motor 90 – 110

Electric Motor Unit

• Material: Die-cast aluminum housing stamped with parallel ribbed fins to optimize the air convection surface area. The terminal box is tightly sealed with heat-resistant silicone gaskets, meeting the IP55 protection standard.
• Characteristics: Winding design optimized for starting current in medium load ranges. The motor operates smoothly, with stable rotational torque and good heat generation amplitude control during continuous running.

2-Stage Gearbox (NMRV 90 + NMRV 110)

• Mechanism: Connects the large-sized aluminum housing primary NMRV 90 gearbox directly into the cavity of the cast iron housing secondary NMRV 110 gearbox. The system shifts the axis at a 90-degree right angle, stepping down speeds hierarchically to achieve an extremely large total transmission ratio for ultra-slow output speeds with high pulling torque.
• Characteristics: The uniform size combination (90 – 110) helps perfectly balance mechanical strength and installation footprint, avoiding the “small head, big base” phenomenon. Rigid frame structure, high static self-locking coefficient, preventing load drift when power is turned off.

Structure of NMRV 2-Stage Gear Motor 90 – 110

The NMRV 2-Stage Gear Motor 90 – 110 is assembled from a 3-phase electric motor 3kW 4Hp with a 2-stage NMRV gearbox precisely machined. The product is assembled from critical components, ensuring high precision and efficiency:

Electric Motor Structure:

• Stator: Located inside the motor, made of solid copper.
• Rotor: The rotating part of the motor, constructed from thin laminated steel sheets.

Gearbox Structure:

• Stage 1 is the NMRV 90 gearbox designed with a sturdy, modern style, suitable for continuous industrial working environments.
• Stage 2 is the NMRV 110 gearbox featuring an outer casing made of solid cast iron or aluminum.

Specifications of NMRV 2-Stage Gear Motor 90 – 110

The 2-stage transmission line NMRV 90 – 110 is configured by combining two worm gearboxes placed in series, providing a deeper speed reduction capability than single-stage configurations. Thanks to this arrangement, the output torque is significantly increased, while the rotational speed is more stably controlled during operation.

Specifications of 3-Phase Electric Motor 2.2kW 3Hp

The motor used in the transmission system has a capacity of 2.2kW, falling into the medium group, designed to maintain stable performance during continuous work. The flange mounting style makes the connection with the gearbox sturdy and limits shaft centerline misalignment during operation.

Specifications of NMRV 90 Gearbox

At the initial stage of the transmission process, the NMRV 90 receives speed from the motor and performs initial speed reduction, helping to stabilize rotational speed before moving to the next stage.

Specifications of NMRV 110 Gearbox

The NMRV 110 takes on the role of speed reduction at the subsequent stage, continuing to lower the output speed and increase torque, helping the system achieve higher transmission efficiency under stable load or medium load conditions.

Applications of NMRV 2-Stage Gear Motor 90 – 110

With the ability to generate high torque and low output speed, the NMRV 2-Stage Gear Motor 90 – 110 is widely applied in industries such as:

• Heavy-duty conveyors, large-scale industrial conveyor belts.
• Mixers, presses, crushers in the material, mineral, and food processing industries.
• Coiling and pulling systems such as steel coilers, cable spoolers, and industrial film winders.
• Woodworking machinery, large-format cutting machines, and metal processing equipment.
• Automation lines requiring continuous operation and high stability.

Guide on Installing Electric Motor with 2 NMRV Gearboxes

• Step 1: Assemble the electric motor to the first gearbox using the included screws.
• Step 2: Insert the intermediate coupling shaft into the output shaft hole of the first gearbox.
• Step 3: Plug the input shaft of the second gearbox into the protruding part of the intermediate coupling shaft.
• Step 4: Tighten the locking screws to securely fix both gearboxes together.

Note: Ensure axial alignment, clean thoroughly before proceeding, and tighten the flange bolts evenly.

The NMRV 2-Stage Gear Motor 90 – 110 is an industrial transmission line designed for systems requiring high torque, stable working capability, and continuous operation in medium to heavy load environments. Thanks to its two-stage worm reduction structure, the device optimizes power transmission capability, accurately controls output speed, and increases durability for the entire machinery system.
