2-Stage NMRV Gear Motor 40 – 75

The 2-Stage NMRV Gear Motor 40 – 75 is a gear motor combined from an electric motor, specifically a 3-phase electric motor, with a gearbox, specifically a 2-stage gearbox. It is a compact solution for systems requiring slow movement and moderate pulling force.

Overview of 2-Stage NMRV Gear Motor 40 – 75

Electric Motor Unit

• Material: The housing is completely cast from ultra-light aluminum alloy, with fine striped heat-dissipation ribs on the surface to enhance air convection. The terminal box is sealed with an outer rubber gasket meeting IP55 protection standards.
• Characteristics: Usually compatible with small-capacity motors. The motor runs smoothly, has a low starting current, and optimizes heat dissipation to protect the oil seal of the primary gearbox assembly.

2-Stage Gearbox (NMRV 40 + NMRV 75)

• Function: Connects the mini NMRV 40 gearbox (primary stage) directly into the cavity of the NMRV 75 gearbox (secondary stage). The mechanism redirects the transmission angle by 90 degrees, multiplying the total transmission ratio to the maximum level to achieve a slow output rotation speed.
• Characteristics: Thanks to both gear sizes 40 and 75 being constructed from monolithic die-cast aluminum housing, the system features an ultra-compact structure, lightweight, and easy mounting in various directions. The mechanism has an absolute static self-locking coefficient, preventing free load drift when power is turned off.

Structure of 2-Stage NMRV Gear Motor 40 – 75

The 2-Stage NMRV Gear Motor 40 – 75 is assembled from a 3-phase electric motor 0.18kW 0.25Hp and a 2-stage NMRV gearbox precisely machined. It is precisely machined with many important components:

Electric Motor Structure:

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

Gearbox Structure:

• Stage 1 is the NMRV 40 gearbox designed with a sturdy, modern style, suitable for continuous industrial working environments.
• Stage 2 is the NMRV 75 gearbox designed with an outer casing made of cast iron or monolithic aluminum.

Specifications of 2-Stage NMRV Gear Motor 40 – 75

The 2-Stage NMRV Gear Motor 40 – 75 is a drive system using two stages of worm gearboxes, helping to expand the transmission ratio range and increase output torque. Thanks to the two-tier connection structure, the device operates more stably in systems requiring low speed and high accuracy.

Specifications of 3-Phase Electric Motor 0.18kW 0.25Hp

The 3-phase electric motor 0.18kW 0.25Hp features a compact design and lightweight, suitable for light-load transmission systems. The IP55 protection class and Class F insulation class help the device operate stably and durably in various environmental conditions.

Specifications of NMRV 40 Gearbox

The NMRV 40 gearbox plays the role of the first reduction stage, helping to reduce speed from the motor and transmit it stably to the next stage in the two-stage system.

Specifications of NMRV 75 Gearbox

The NMRV 75 gearbox is the second reduction stage, helping to increase output torque and complete the reduction process, ensuring the system operates stably and smoothly.

Applications of 2-Stage NMRV Gear Motor 40 – 75

The NMRV 40 – 75 gear motor is widely used in many systems requiring low speed and high torque, such as:

• Production conveyors, goods sorting conveyors.
• Agitators, mixers, and grinders in the food and materials industries.
• Winding systems such as film winders, wire winders, and fabric winders.
• Fabric cutting machines, woodworking machines, metal processing equipment.
• Automation systems operating continuously and requiring high precision.

Instructions for Installing Electric Motor with 2 NMRV Gearboxes

• Step 1: Place the electric motor close to the face of gearbox 1, then tighten the bolts securely.
• Step 2: Place the intermediate coupling shaft into the exact output shaft hole position of gearbox 1.
• Step 3: Position gearbox 2 so that its input shaft aligns precisely with the intermediate coupling shaft.
• Step 4: Tighten the bolts connecting the two gearboxes to keep them stationary and free from vibration.

Note: Keep the shaft straight, clean off any dust adhering to the shaft, and tighten the bolts in a rotating pattern.

The 2-Stage NMRV Gear Motor 40 – 75 is a compact transmission solution, suitable for systems requiring low speed, stable torque, and long-term durable operation, widely applied in many production lines and industrial machinery.
