2-Stage NMRV Gear Motor 75 – 110

The 2-stage NMRV 75 – 110 gear motor is a gear motor line combined from an electric motor, specifically a 3 phase electric motor, with a gearbox, specifically a 2-stage gearbox, featuring fast heat dissipation, superior corrosion resistance, and excellent heavy-duty load capacity. The product is especially suitable for industries such as heavy-duty conveyors, wood processing lines, material pressing and rolling machines, industrial coiling systems, and automation lines requiring high stability, durability, and powerful transmission performance.

Overview of 2-Stage NMRV Gear Motor 75 – 110

Electric Motor Unit

• Material: Aluminum alloy housing embossed with vertical ribs to enhance the heat dissipation area. The terminal box is sealed with a shaped rubber gasket, meeting IP55 protection standards for good dust and water jet resistance.
• Characteristics: Optimized winding design for a stable starting torque range. The motor operates smoothly, with low no-load current and good temperature control during long cycle runs to protect the primary gear assembly.

2-Stage Gearbox (NMRV 75 + NMRV 110)

• Mechanism: Connects the primary aluminum-housed NMRV 75 directly into the cavity of the secondary cast-iron-housed NMRV 110. The system bends the axis at a 90-degree right angle and reduces speed in stages to achieve an ultra-large total transmission ratio for extremely slow output speeds and strong traction.
• Characteristics: The 75 assembly housing is made of aluminum to optimize hanging weight; the 110 assembly housing is made of thick cast iron to withstand torsional force and provide good impact resistance. The combination features high mechanical self-braking capability, preventing free load drift when power is disconnected.

Structure of 2-Stage NMRV Gear Motor 75 – 110

The NMRV 75 – 110 gear motor is assembled from a 3 phase electric motor 2.2kW 3Hp and a precisely machined 2-stage NMRV gearbox. The product is manufactured from high-precision components, delivering stable performance and a long lifespan. Details are as follows:

Electric Motor Structure:

• Stator: Cast from 100% pure copper with a thick, highly durable housing, serving as the stationary internal part of the motor.
• Rotor: Constructed from lightweight thin steel sheets to enhance operational capacity, serving as the rotating part driven by the action generated by the stator.
• The rear part of the motor is equipped with an additional cooling fan to cool the motor during operation.

Gearbox Structure:

• Stage 1 is the NMRV 75 gearbox featuring a sturdy, modern design suitable for continuous industrial working environments.
• Stage 2 is the NMRV 110 gearbox featuring an outer housing made of solid cast iron or aluminum.

Technical Specifications of 2-Stage NMRV Gear Motor 75 – 110

The 2-stage NMRV 75 – 110 gear motor unit is constructed with a configuration of two consecutive worm gearboxes connected in series to enhance reduction capability and improve output traction. The dual transmission stage design helps distribute the load reasonably between stages, thereby increasing stability when operating at low speeds and extending equipment lifespan.

Technical Specifications of 3-Phase 1.5kW 2HP Electric Motor

The power section of the system uses a 1.5kW motor, suitable for medium-load applications and continuous operation requirements. The flange structure supports a secure connection with the gearbox, ensuring high concentricity during transmission.

Technical Specifications of NMRV 75 Gearbox

NMRV 75 acts as the first reduction stage, receiving speed from the motor and performing preliminary reduction, helping to stabilize rotation before transferring to the next stage.

Technical Specifications of NMRV 110 Gearbox

NMRV 110 is the second reduction stage in the system, undertaking the task of deeper speed reduction and torque increase, helping the transmission system achieve higher working efficiency and greater stability under heavy loads or continuous operation.

Applications of 2-Stage NMRV Gear Motor 75 – 110

Thanks to its ability to generate high torque and high stability, the NMRV 75 – 110 gear motor is used in many industrial fields, especially systems requiring large loads:

• Heavy-duty conveyors and goods sorting conveyor lines.
• Mixers, grinders, and presses in the material, mineral, and food industries.
• Industrial coiling systems such as steel coilers, cable spoolers, and film winders.
• Wood processing machines, large-format cutting machines, and metal processing equipment.
• Automated production lines operating continuously in manufacturing workshops.

Guide to Installing Electric Motor with Dual NMRV Gearboxes

• Step 1: Firmly attach the electric motor to gearbox 1 using the available screws.
• Step 2: Insert the intermediate coupling shaft through the output shaft hole of gearbox 1.
• Step 3: Plug the input shaft of gearbox 2 directly into the intermediate coupling shaft bar.
• Step 4: Tighten the screws to secure the two gearboxes in place, preventing them from slipping out.

Note: The shafts must be completely straight, wipe the mating surfaces clean, and tighten the screws evenly.
