3-Stage Gear Motor (2 UDL 1.5kW and 1 NMRV 75)

The 3-Stage Gear Motor (2 UDL 1.5kW and 1 NMRV 75) is a gear motor assembled from an electric motor-specifically a 3-phase electric motor-combined with a gearbox, specifically a 3-stage gearbox, which helps adjust speed, allowing speed changes while the machine is running. It increases flexibility for production lines with a wide adjustment range, suitable for various applications. This is a deep reduction gearbox with high torque, smooth operation, and reduced noise. The thick cast iron or aluminum housing is sturdy, offers high load capacity, and provides effective self-braking to ensure safety when stopping loads.

Overview of the 3-Stage Gear Motor (2 UDL 1.5kW and 1 NMRV 75)

The 3-Stage Gear Motor (2 UDL 1.5kW and 1 NMRV 75) is a compact product with excellent load performance, making the motor easy to install in systems with limited space or complex transmission layout requirements. Thanks to its three-stage reduction structure, the device allows for very slow output speeds, uniform and precise movement, and high stability. This is an ideal choice for applications requiring 24/7 operation or continuous heavy-duty loads in processing, manufacturing, and industrial mechanical sectors.

Structure of the 3-Stage Gear Motor (2 UDL 1.5kW and 1 NMRV 75)

The 3-Stage Gear Motor (2 UDL 1.5kW and 1 NMRV 75) is a gear motor line ranging from 1.1kW to 3.7kW (1.1kW to 3.7kW gear motor) structured from a 3-phase electric motor 1.5kW 2Hp combined with a 3-stage gearbox (2 UDL 1.5kW and 1 NMRV 75). Its detailed structure is as follows:

Electric motor structure:

• Motor housing: Machined from cast iron or aluminum alloy, protecting internal components and assisting with heat dissipation.
• Rotor: Precisely machined, transmitting rotational movement directly to the speed variator.
• Stator: Wound with Class F insulated copper wire, meeting continuous operation requirements.
• Terminal box: Sealed design, convenient for wiring connection and terminal protection.
• Cooling fan: Positioned at the rear of the motor, helping maintain a stable working temperature

Gearbox structure:

• Stage 1 is the mechanical speed variator (UDL): Specifically, the 1.5kW 2Hp mechanical speed variator features a friction disc – cone disc assembly, input/output shafts, and an adjustment knob, allowing stepless speed variation before entering the gearbox.
• Stage 2 is the 2-stage gearbox: Specifically, the UDL 1.5kW – NMRV 75 2-stage gearbox creates a large gear ratio and high torque with smooth operation.

Instructions on how to assemble the electric motor with 2 UDLs and 1 NMRV

To assemble the electric motor with 2 UDLs and 1 NMRV into a 3-stage transmission system, follow the correct sequence to ensure that the transmission assemblies are securely connected, transmit stable torque, and operate durably.

Step 1: Connect the electric motor to the first UDL

Insert the shaft of the electric motor into the input of the first UDL variator. Align the shaft and flange concentrically, then evenly tighten the bolts to create a firm connection, reducing vibration and increasing operational stability.

Step 2: Install the second UDL into the transmission assembly

Couple the output of the first UDL with the input of the second UDL. Check the meshing between parts, secure the connection bolts, and test-rotate the shaft to ensure the variator assembly operates smoothly.

Step 3: Connect with the NMRV gearbox

Install the electric motor and two UDL units assembly into the input of the NMRV gearbox. Align the key, shaft, and flange in the correct position, then tighten all bolts to the appropriate torque. Before powering on, check the shaft’s rotational capability to ensure the system operates safely.

Combining two UDL variators with an NMRV gearbox creates a 3-stage transmission system capable of flexible speed adjustment, increased torque, and excellent performance in low-speed applications such as agitators, conveyors, packaging machines, mixers, and various other industrial equipment.
