2-Stage NMRV Gear Motor 50 – 75

The 2-Stage NMRV Gear Motor 50 – 75 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 is designed with an international standard flange, allowing for quick assembly, easy replacement, and convenient system expansion or upgrading.

Overview of 2-Stage NMRV Gear Motor 50 – 75

Electric Motor Block

• Material: The housing is entirely cast from lightweight aluminum alloy, integrated with heat dissipation ribs to optimize convective airflow. The terminal box is tightly sealed with a heat-resistant rubber gasket, meeting the IP55 protection standard for good dust and water jet resistance.
• Characteristics: Compatible with small capacity motors, low starting current, smooth operation, and minimal electromagnetic heat generation, helping to protect the ultra-small gear stages of the primary stage.

2-Stage Gearbox (NMRV 50 + NMRV 75)

• Function: Connects the smaller NMRV 50 gearbox in series with the central NMRV 75 gearbox in a modular design. The system redirects the drive at a 90-degree right angle, creating a maximum transmission ratio range for output speeds approaching zero with high pulling torque.
• Characteristics: Both sizes 50 and 75 use monolithic die-cast aluminum alloy housings, providing an ultra-lightweight, highly aesthetic overall structure and easy mounting on vertical machine walls. The worm gear mechanism provides high static self-locking capability, holding the load fixed when power is cut.

Structure of 2-Stage NMRV Gear Motor 50 – 75

The 2-Stage NMRV Gear Motor 50 – 75 is assembled from a 3 phase gear motor 0.55kW 0.75Hp and a 2-stage NMRV gearbox precisely machined. The system includes the following important components:

Electric motor structure:

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

Gearbox structure:

• The 1-Stage is the NMRV 50 gearbox featuring a sturdy, modern design, suitable for continuous industrial working environments.
• The 2nd stage is the NMRV 75 gearbox with an outer casing made of solid cast iron or aluminum.

Specifications of 2-Stage NMRV Gear Motor 50 – 75

The 2-Stage NMRV Gear Motor 50 – 75 is a transmission unit consisting of two worm-worm gear reduction stages, helping to expand the transmission ratio and increase output torque capacity. Thanks to a reasonable coupling structure, the device operates stably, minimizes vibration and noise, and is suitable for systems requiring low speed and stable load.

Specifications of 3 phase electric motor 0.37kW 0.5Hp

The 3-phase electric motor 0.37kW 0.5Hp is designed to be compact, easy to install, and ensures stable working performance over a long period. The IP55 protection class increases dust and moisture resistance, making it suitable for various industrial environments.

NMRV 50 gearbox specifications

The NMRV 50 gearbox acts as the first reduction stage, helping to reduce rotational speed from the motor and stably transmit it to the next reduction stage in the two-stage system.

NMRV 75 gearbox specifications

The NMRV 75 gearbox is the second reduction stage, helping to complete the reduction process, increase torque, and ensure stable transmission efficiency for the entire system.

Applications of 2-Stage NMRV Gear Motor 50 – 75

The NMRV 50 – 75 gear motor is widely applied in production lines requiring low speed but high torque. Some common applications:

• Industrial conveyors, conveyor belts in manufacturing plants.
• Mixers, agitators, crushers in the food, agricultural product, and material industries.
• Traction – winding systems such as film winders, fabric winders, wire winders.
• Fabric cutting machines, woodworking machines, mechanical processing equipment.
• Continuous automation lines requiring high stability and precision.

Instructions for installing electric motor with 2 NMRV gearboxes

• Step 1: Fasten the electric motor tightly to the first gearbox and tighten the screws.
• Step 2: Insert the intermediate coupling shaft neatly inside the output shaft hole of the newly installed gearbox.
• Step 3: Engage the input shaft of the remaining gearbox to mesh with the exposed end of the intermediate coupling shaft.
• Step 4: Tighten the screws to lock the two gearboxes tightly into a single solid block.

Note: Align the shafts, clean the installation area thoroughly, and tighten the screws gradually and evenly.

The 2-Stage NMRV Gear Motor 50 – 75 is a suitable transmission solution for systems requiring low speed, high torque, and stable operation.
