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

The 3-stage gear motor (2 UDL 1.5kW and 1 WPDA 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. Featuring a right-angle shaft design, it makes the equipment more compact and easier to install in tight spaces or systems with structural limitations. With the ability to generate very low speeds, smooth transmission, and high torque, this gear motor is suitable for applications requiring stable, uniform, and precise movement over long periods.

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

The 3-stage gear motor (2 UDL 1.5kW and 1 WPDA 80) is designed according to modern industrial mechanical standards, offering high durability and heavy-duty load capacity. The three reduction stages are arranged in a scientific sequence: stepless speed reduction → intermediate reduction → primary reduction, ensuring even speed reduction and stable torque transmission. The motor housing and gearbox housing are manufactured from cast iron or solid aluminum alloy.

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

The 3-stage gear motor (2 UDL 1.5kW and 1 WPDA 80), a gear motor ranging from 1.1kW to 3.7kW, is formed by combining a 3-phase electric motor 1.5kW 2Hp with a 3-stage gearbox (2 UDL 1.5kW and 1 WPDA 80), creating a multi-stage transmission assembly that operates stably and flexibly.

Electric Motor Structure:

• Motor Housing: Cast from iron or aluminum alloy with vertical ribs, providing optimal heat dissipation and excellent resistance to vibration when the system pulls heavy loads continuously.
• Rotor: Standard-sized centered rotating shaft, pressed from high-magnetic technical steel sheets, with precise dynamic balancing for powerful power transmission.
• Stator: Magnetic core wound from large-cross-section pure copper wire, with Class F insulation to withstand high temperatures during heavy-duty operation.
• Terminal Box: Contains the power terminal block, equipped with waterproof rubber gaskets and tightly secured cable outlets, meeting the IP55 dust and water protection standard.
• Motor Rear End: Integrates a high-power cooling fan and a rigid steel protective cover, maintaining a continuous cooling airflow.

Gearbox Structure:

• Stage 1 is a mechanical speed variator (UDL): Specifically, the 1.5kW 2Hp mechanical speed variator consists of a friction disc – cone disc assembly, input/output shafts, and an adjustment knob, allowing stepless speed changes before entering the gearbox.
• Stage 2 is a 2-stage gearbox: Specifically, the UDL 1.5kW – WPDA 80 2-stage gearbox creates a large gear ratio and high torque for smooth operation.
• Housing, Bearings, and Lubrication System: Sturdy cast iron/aluminum housing, load-bearing bearings, and gear oil lubrication help reduce friction, dissipate heat, and increase durability.

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

With high torque generated from the 1.5kW motor combined with the WPDA 80 32mm solid shaft gearbox and ultra-low rotational speed, this system is specialized in applications such as:

• Ore and rock feeding conveyors, bucket elevator systems in mining and cement plants.
• Thick adhesive mixers, large-capacity microbial incubation tanks, industrial sludge aeration tanks.
• Anchor cable winch mechanisms, heavy-duty discharge hopper lifting and lowering systems.
• Wood pressing roller shafts, recycled plastic pressing shafts, metal corrugated roofing roll-forming machines, or continuous thermal drying lines.

Guide on How to Install an Electric Motor with 2 UDL Units and 1 WPDA Gearbox

To form a 3-stage gear motor using 2 UDL units and 1 WPDA gearbox, the assembly process must be performed correctly to ensure stable power transmission, smooth operation, and extended equipment lifespan.

Step 1: Install the electric motor onto the first UDL unit

Insert the shaft of the electric motor into the input shaft of the first UDL speed variator. Check the installation position, ensure the shaft is properly centered, and tighten the connecting bolts to securely fix the transmission assembly.

Step 2: Connect the second UDL unit

Connect the output of the first UDL unit to the input of the second UDL unit. After coaxial alignment, tighten the bolts and check the shaft’s rotation capability to ensure the transmission system operates smoothly.

Step 3: Couple the transmission assembly with the WPDA gearbox

Install the assembly consisting of the electric motor and the two UDL units onto the WPDA gearbox, while aligning the keyway and flange so that all components fit accurately. After completing the installation, recheck all connection points before putting the equipment into operation.

When the two UDL speed variators are combined with the WPDA gearbox, the system forms a 3-stage drive unit capable of flexible speed reduction, increased torque, and effectively meeting the demands of equipment requiring low rotational speeds such as mixers, conveyors, blenders, or production lines.
