3-Stage Gear Motor (2 UDL 1.5kW and 1 WPDS 80)

The 3-Stage Gear Motor (2 UDL 1.5kW and 1 WPDS 80) is a gear motor assembled from an electric motor, specifically a 3-phase electric motor, combined with a gearbox, specifically a 3-stage gearbox. Thanks to the right-angle output shaft design, the motor assembly is extremely compact and easy to install in spatially constrained positions or complex drive systems. This product line is especially suitable for applications requiring slow speeds, precise transmission, smooth movement, and long-term stable operation.

Overview of the 3-Stage Gear Motor (2 UDL 1.5kW and 1 WPDS 80)

The 3-Stage Gear Motor (2 UDL 1.5kW and 1 WPDS 80) is designed according to modern mechanical standards with high durability and superior load capacity. Three reduction stages are arranged in a logical sequence: speed adjustment → intermediate reduction → primary reduction. Thanks to this structure, the speed decreases step-by-step, helping to minimize load shock and generate a stable output torque even under heavy-duty conditions. The housing of the motor and gearbox is made of cast iron or solid aluminum alloy.

Structure of the 3-Stage Gear Motor (2 UDL 1.5kW and 1 WPDS 80)

The 3-Stage Gear Motor (2 UDL 1.5kW and 1 WPDS 80) is a gear motor ranging from 1.1kW to 3.7kW, assembled from a 3-phase electric motor 1.5kW 2Hp and a 3-stage gearbox (2 UDL 1.5kW and 1 WPDS 80) with detailed structure as follows:

Electric motor structure:

• Stator: Made of 100% copper wire with high efficiency and superior durability.
• Rotor: Used for good balancing, reducing vibration, and increasing smoothness during operation.

Gearbox structure:

• Stage 1 is the mechanical speed variator (UDL): Specifically, the 1.5kW 2Hp mechanical speed variator consisting of friction disc – cone disc assemblies, 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 – WPDS 80 2-stage gearbox creating a large transmission ratio and high torque for smooth operation.
• Housing, bearings, and lubrication system: Sturdy cast iron/cast aluminum housing, load-bearing bearings, and lubricating gear oil help reduce friction, dissipate heat, and increase durability.

Applications of the 3-Stage Gear Motor (2 UDL 1.5kW and 1 WPDS 80)

With the characteristic of generating extremely slow rotational speeds, very strong pulling force (thanks to the 1.5kW motor and WPDS 80), and flexible fine-tuning capabilities, this equipment assembly is applied in:

• Heavy-duty conveyor systems and large-volume feeding conveyors in the mining and cement industries.
• Thick chemical mixers, microbial incubation tanks, and large-capacity sludge aeration tanks requiring high resistance force but extremely slow mixing speeds.
• Winch mechanisms and slow rolling/pressing rollers in metallurgy plants, sheet metal rolling, or plastic extrusion mills.
• Continuous thermal drying conveyor systems with large batch workpieces requiring long drying time delays.

Instructions on how to install an electric motor with 2 UDL and 1 WPDS

To complete the electric motor system combining 2 UDL and 1 WPDS, installation must follow the correct procedure to ensure stable transmission, efficient speed reduction, and increased lifespan for the entire system.

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

Install the output shaft of the electric motor into the first UDL variator, while aligning the shaft center and flange so that the parts mesh accurately. Then tighten the connecting bolts to create a solid structure before moving on to the next step.

Step 2: Connect the second UDL unit

Continue coupling the output of the first UDL to the input of the second UDL. After checking the concentricity and meshing capability of the parts, tighten all bolts to ensure the speed variator assembly operates stably during power transmission.

Step 3: Install the drive assembly into the WPDS gearbox

Place the electric motor and two UDL units into the WPDS gearbox. Align the key, shaft, and flange in the correct position before fixing them with bolts. Finally, manually rotate the shaft to check the smoothness of the mechanism before putting the equipment into operation.

When two UDL speed variators are combined with the WPDS gearbox, the system will form a 3-stage drive system capable of deep reduction, maintaining high torque, and well meeting heavy-load, low-speed applications such as mixers, conveyors, presses, blenders, and many industrial production lines.
