3-Stage Gear Motor (2 UDL 1.5kW and 1 WPDA 100)

The 3-Stage Gear Motor (2 UDL 1.5kW And 1 WPDA 100) is a gear motor assembled from an electric motor-specifically a 3-phase electric motor-combined with a gearbox, specifically a 3-stage gearbox of the right-angle shaft type. This gives the motor a compact design, making it easy to install in confined spaces or drive systems requiring a change in output shaft direction. Thanks to its three consecutive reduction stages, the motor delivers extremely low speed, strong pulling force, stable transmission, and well satisfies long-term working requirements in heavy-duty environments.

Design Overview of the 3-Stage Gear Motor (2 UDL 1.5kW And 1 WPDA 100)

The 3-Stage Gear Motor (2 UDL 1.5kW And 1 WPDA 100) is manufactured with a robust mechanical structure, high load capacity, and high-intensity operational capability. The reduction assembly consists of the UDL mechanical speed variator → intermediate reduction → WPDA reduction, allowing stage-by-stage speed reduction, limiting shock loads, and maintaining stable torque. The motor housing and WPDA gearbox are made of cast iron or solid aluminum alloy.

Detailed Structure of the 3-Stage Gear Motor (2 UDL 1.5kW And 1 WPDA 100)

The 3-Stage Gear Motor (2 UDL 1.5kW And 1 WPDA 100) is a gear motor line from 1.1kW to 3.7kW assembled from a 3-phase 1.5kW 2Hp electric motor with a 3-stage gearbox (2 UDL 1.5kW and 1 WPDA 100), with the following detailed structure:

Electric Motor Structure:

• Motor housing: Cast from iron or shaped aluminum alloy, providing the necessary rigidity and heat dissipation area when the machine runs continuously.
• Rotor: Manufactured with absolute concentricity to the transmission shaft, supporting smooth torque transmission to the reduction assembly.
• Stator: Magnetic core wound with 100% Class F standard insulated copper wire, maintaining operational capacity at rated load.
• Terminal box: Arranges safe electrical wiring terminals, using rubber gaskets for shielding to achieve IP55 water and dust resistance protection level.
• Motor rear end: Equipped with a cooling fan accompanied by a protective iron cage, helping to lower the motor temperature during long working cycles.

Gearbox Structure:

• Stage 1 and Stage 2 (Dual UDL Mechanical Speed Variators): Two UDL speed variator units compatible with a 1.5kW load connected in series. The device uses a friction cone disc mechanism and a mechanical knob for stepless speed change.
• Stage 3 (WPDA 100 Worm Gearbox): Acts as the final speed reduction stage. Uses a worm and brass worm wheel mechanism to create extremely slow output speed and high twisting torque.
• Bearing and lubrication system: The shafts are supported by heavy-duty bearings, combined with industrial lubrication oil immersion to reduce sliding friction and extend gear teeth lifespan.

Common Applications of the 3-Stage Gear Motor (2 UDL 1.5kW And 1 WPDA 100)

With a power rating of 1.5kW combined with a large size 100 gearbox, this configuration has the ability to squeeze rotation down to very slow levels while maintaining strong pulling force, applied effectively in:

• Large-volume material feeding conveyor systems, material bucket elevators in construction material and mining factories.
• Thick industrial chemical mixing tanks, large-capacity sludge stirring machines requiring slow rotation speed and high resistance.
• Cable pulling machine mechanisms, heavy-load steel/plastic film unwinding and rewinding machines requiring stability.
• Rubber calendering systems, thermal dryer rollers, or slow automatic feeding mechanisms.

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

To complete the electric motor assembly combined with 2 UDL and 1 WPDA, it is necessary to assemble step-by-step to ensure the drive system operates accurately, stably, and achieves optimal performance.

Step 1: Connect the electric motor to the first UDL unit

Install the output shaft of the electric motor into the input of the first UDL speed variator. Align the position between the shaft and the flange to ensure concentricity, then evenly tighten the bolts to create a secure connection and minimize vibration during operation.

Step 2: Attach the second UDL unit to the system

Continue installing the output of the first UDL to the input of the second UDL. Check the shaft meshing capability, then secure all joint locations. Two UDL units working in series will help adjust speed more flexibly before transmitting power to the gearbox.

Step 3: Install the drive assembly onto the WPDA gearbox

Bring the motor assembly and two UDL units into the input of the WPDA gearbox. Accurately align the key, shaft, and flange before tightening the bolts with appropriate torque. Upon completion, manually rotate the shaft to check the transmission capability and stability of the entire system.

The combination of two UDL speed variators and a WPDA gearbox creates a 3-stage drive system capable of effective speed reduction, increased output torque, and well-suited for low-speed, high-load applications such as stirrers, conveyors, mixers, and various industrial equipments.
