3-Stage Gear Motor (2 UDL 2.2kW And 1 WPDS 120)

The 3-Stage Gear Motor (2 UDL 2.2kW And 1 WPDS 120) is a gear motor assembled from an electric motor specifically a 3-phase electric motor combined with a gearbox specifically a 3-stage gearbox. With a compact vertical design, it is easy to install and optimized for industrial machinery that requires continuously variable speeds while demanding strong traction, such as large agitators, heavy-duty conveyors, material mixing systems, and processing equipment in large-scale production environments.

Overview Design of the 3-Stage Gear Motor (2 UDL 2.2kW And 1 WPDS 120)

The 3-Stage Gear Motor (2 UDL 2.2kW And 1 WPDS 120) features a bright aluminum alloy housing and a large disk-shaped speed control knob on top. When stacked together, the two UDL units form a seamless block, with surrounding heat dissipation ribs to ensure continuous heat dissipation during operation. The bottom flange of the second UDL unit is securely bolted to the underlying WPDS gearbox with an even array of bolts, ensuring stable power transmission across the three stages.

Detailed Structure of the 3-Stage Gear Motor (2 UDL 2.2kW And 1 WPDS 120)

The 3-Stage Gear Motor (2 UDL 2.2kW And 1 WPDS 120) is a gear motor line ranging from 1.1kW to 3.7kW, assembled from a 3-phase 2.2kW 3Hp electric motor and a 3-stage gearbox (2 UDL units and 1 WPDS gearbox) with the following detailed structure:

Electric Motor Structure:

• Motor Housing: Cast in monolithic cast iron with large vertical ribs, optimizing heat dissipation and withstanding extremely good vibration when the system pulls heavy loads continuously.
• Rotor: Large-sized centered rotating shaft, pressed from high magnetic technical steel sheets, dynamically balanced accurately for powerful power transmission.
• Stator: The magnetic core is wound from large cross-section pure copper wire, with Class F insulation layer to withstand high temperatures when operating at maximum intensity.
• Terminal Box: Contains a large power terminal block, equipped with a waterproof rubber gasket and tightly secured cable outlets, meeting the IP55 dust and water protection standard.
• Motor Rear Cover: Integrates a high-power cooling fan and a hard steel protective cover, maintaining a continuous cooling airflow.

Gearbox Structure:

• Stage 1:Mechanical speed variator (UDL), specifically a 2.2kW 3Hp mechanical speed variator consisting of a thick cast aluminum alloy housing surrounding the friction disk assembly and pressing ring to change the gear ratio.
• Stage 2:2-stage gearbox, specifically the UDL 2.2kW – WPDS 120 2-stage gearbox. The output shaft is a large solid shaft with a keyway, reinforced with large-sized bearings to withstand high loads. Oil filling, draining, and venting holes arranged around the housing body facilitate convenient lubrication and maintenance.
• Input Shaft: Receives speed from the motor and drives the transmission system.
• Output Shaft: Outputs the reduced speed in the form of a solid or hollow shaft with a keyway.

Applications of the 3-Stage Gear Motor (2 UDL 2.2kW And 1 WPDS 120)

Thanks to its wide speed adjustment capability and strong traction from the worm gear stage, the 3-stage gear motor is effectively applied in many industrial fields requiring flexible operation while enduring heavy loads:

• Large volume agitators requiring speed changes according to each processing stage.
• Heavy-duty conveyors running continuously and requiring strong torque at low speeds.
• Industrial material mixers requiring speed adjustment based on viscosity or individual stages.
• Food and chemical processing lines requiring equipment to operate stably yet flexibly in speed.
• Material lifting and pushing systems requiring high torque and precise speed control.

Guide on How to Install the Electric Motor with 2 UDL and 1 WPDS Units

To install the electric motor with 2 UDL and 1 WPDS units, the correct procedure must be followed to ensure that the drive assemblies mesh accurately, operate stably, and maximize speed reduction efficiency.

Step 1: Couple the electric motor with the first UDL unit

Place the shaft of the electric motor into the input shaft of the first UDL variator, while checking the concentricity between the two components. Once aligned, tighten the bolts in sequence to increase stability and minimize vibration during operation.

Step 2: Connect the second UDL unit

Continue linking the output of the first UDL to the input of the second UDL. After proper alignment, secure all joints and check the shaft’s rotational capability to ensure a smooth drive system.

Step 3: Connect with the WPDS gearbox

Bring the motor assembly and the two UDL units into the WPDS gearbox, aligning the key and shaft so that components mesh completely before tightening the flange. After installation, it is recommended to manually rotate to check the smoothness of the entire mechanism before supplying power for operation.

The combination of two UDL speed variators with the WPDS gearbox forms a 3-stage drive system capable of deep speed reduction, maintaining stable torque, and well-suited for low-speed applications such as agitators, conveyors, presses, or industrial production lines.
