NMRV 2-Stage Gear Motor 75 – 90

The NMRV 2-Stage Gear Motor 75 – 90 is a gear motor combined from an electric motor (specifically a 3-phase electric motor) and a gearbox (specifically a 2-stage gearbox). The device creates a high transmission ratio, smooth operation, low vibration, and is suitable for various medium to heavy load applications such as industrial conveyors, crushers, mixers, winding systems, and factory automation lines.

Overview of the NMRV 2-Stage Gear Motor 75 – 90

Electric Motor Block

• Material: Extruded aluminum alloy housing stamped with parallel wavy ribs to optimize cooling airflow. Terminal box sealed with heat-resistant rubber gaskets, meeting IP55 protection standards.
• Characteristics: Optimized winding design for stable starting torque in the mid-range power band, low no-load current, smooth operation, and good control of heat generation amplitude to protect the oil seal of the primary reduction unit.

2-Stage Gearbox (NMRV 75 + NMRV 90)

• Mechanism: Connects the primary NMRV 75 gearbox directly into the secondary NMRV 90 gearbox cavity. The pair turns the power flow at a 90-degree right angle, providing tiered speed reduction to achieve a super-large overall transmission ratio for slow output speeds.
• Characteristics: Thanks to both stage 75 and 90 housings being constructed from monolithic die-cast aluminum, the system features a very compact structure, high aesthetics, and easy multi-directional suspension mounting on vertical machine walls without worrying about support base weight overload. The mechanism features high static self-locking performance, preventing free load drift.

Structure of the NMRV 2-Stage Gear Motor 75 – 90

The NMRV 75 – 110 gear motor is assembled from a 3-phase electric motor 1.1kW 1.5Hp with a 2-stage NMRV gearbox (NMRV gearbox) manufactured with high precision, comprising several key components:

Electric Motor Structure:

• Stator: Cast from 100% pure copper, with a thick, high-durability shell, serving as the stationary part located inside the motor.
• Rotor: Constructed from lightweight steel laminations, enhancing operational capability. It is the rotating part, driven by the magnetic field created by the stator.
• The rear of the motor is fitted with a 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 90 gearbox featuring an outer housing made of solid cast iron or aluminum.

Specifications of the NMRV 2-Stage Gear Motor 75 – 90

The NMRV 2-Stage Gear Motor 75 – 90 is a transmission solution designed to meet the demand for large reduction ratios while maintaining a compact structure. The combination of two NMRV gearboxes allows the device to create a diverse output speed range, while enhancing torque transmission efficiency and reducing motor load during operation.

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

The 3-phase electric motor 1.5kW 2Hp is used to provide a stable power source for the entire transmission assembly. Designed to IP55 standards and Class F insulation, the motor is capable of continuous operation, minimizing the effects of dust and industrial environments.

Specifications of the NMRV 75 Gearbox

The NMRV 75 is positioned first in the two-stage transmission assembly, functioning to receive power directly from the motor and perform the initial reduction process.

Specifications of the NMRV 90 Gearbox

After power is transmitted from the first stage, the NMRV 90 gearbox performs the second reduction stage, increasing torque and optimizing the efficiency of the entire system.

Applications of the NMRV 2-Stage Gear Motor 75 – 90

The NMRV 75 – 90 gear motor series has high load-bearing capacity and stable transmission, suitable for various industries:

• Heavy-duty conveyors and conveyor belts in sorting and transportation lines.
• Mixers, agitators, and crushers in the food, pharmaceutical, and material industries.
• Winding systems such as film rollers, fabric rollers, and industrial wire rollers.
• Woodworking machinery, large-format cutting machines, and mechanical processing equipment.
• Automation lines requiring continuous, stable, and precise operation.

Instructions for Installing the Electric Motor with 2 NMRV Gearboxes

• Step 1: Attach the electric motor to gearbox 1 and tighten the screws firmly.
• Step 2: Insert the intermediate coupling shaft into the hole of the output shaft on gearbox 1.
• Step 3: Mount gearbox 2 by connecting its input shaft to the intermediate coupling shaft.
• Step 4: Use screws to secure both gearbox bodies firmly together.

Note: Align the shafts perpendicularly, wipe the contact points completely clean, and tighten all screws evenly.
