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

The 3-stage gear motor (2 UDL 2.2kW and 1 WPDX 120) is a gear motor line assembled from an electric motor, specifically a 3-phase electric motor combined with a gearbox, specifically a 3-stage gearbox. The product operates smoothly, durably, is easy to install, and is compatible with various machines such as agitators, mixers, conveyors, processing equipment, and production lines requiring flexible speeds.

General Design of the 3-Stage Gear Motor (2 UDL 2.2kW and 1 WPDX 120)

The 3-stage gear motor (2 UDL 2.2kW and 1 WPDX 120) features a connected cylindrical body design with a bright aluminum surface for good heat dissipation. The UDL body has an easy-to-operate speed adjustment knob, allowing smooth speed changes while the machine is running. The connecting flanges between parts are precisely machined to ensure high concentricity.

The overall drive assembly creates an impression of sturdiness, compactness, and professionalism, suitable for systems requiring stable, flexible, and durable operation in industrial environments.

Detailed Structure of the 3-Stage Gear Motor

The 3-stage gear motor (2 UDL 2.2kW and 1 WPDX 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 2.2kW and 1 WPDX 120) with the following detailed structure:

Electric motor structure:

• The motor housing is made of cast iron or aluminum alloy, serving to fix the entire structure and support heat dissipation when the motor operates for long periods.
• The stator core and laminated steel core windings combined with copper windings create a stable rotating magnetic field, serving as the main pulling force for the rotor to operate.
• The squirrel-cage rotor and drive shaft attached to the steel shaft are the moving parts that receive force from the stator and output torque to the transmission system.
• The fan system and cooling fan shaft bearings installed at the rear of the motor help regulate temperature, while ball bearings keep the shaft rotating in balance, reduce friction, and increase motor lifespan.

Gearbox structure:

• Stage 1: Mechanical Speed Variator (UDL), specifically the 2.2kW 3Hp mechanical speed variator: Serves as the protective frame for all internal gears, containing lubricating oil and helping dissipate heat when the equipment operates continuously.
• Stage 2: 2-stage gearbox, specifically the UDL 2.2kW – WPDX120 2-stage gearbox with small-large gear sets or worm gear transmissions depending on the design, taking charge of initial speed reduction to increase transmission force.
• The output shaft, ball bearings, and output shaft oil seal receive the final force to transmit to the machine; ball bearings keep the shaft rotating smoothly; oil seals retain lubricating oil and limit dust ingress.

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

Thanks to its flexible speed variation capability and powerful power transmission, the 3-stage gear motor (2 UDL 2.2kW and 1 WPDX 120) is chosen for many modern production systems.

• Used for agitators and low-speed mixers where smooth speed adjustment is needed while maintaining high torque.
• Applied in long conveyors and material handling systems requiring stable operation.
• Installed in industrial mixers, supporting uniform mixing across various speed ranges.
• Suitable for continuous production lines that require durable operation and speed adjustment according to each production stage.

How to Assemble an Electric Motor with 2 UDLs and 1 WPDX Gearbox to Create a 3-Stage Gear Motor

Below are the steps to assemble an electric motor with 2 UDLs and 1 WPDX gearbox to form a 3-stage gear motor:

• Step 1: Insert the shaft of the electric motor directly into the female shaft of the first UDL unit, and tighten the flange securely. Immediately afterwards, continue connecting the output shaft end of UDL 1 to the second UDL unit. During this process, pay attention to the tightness of the connecting grooves to create a smooth and stable dual speed adjustment range.
• Step 2: Connect the WPDX worm gearbox. After having the primary assembly unit (Motor + 2 UDLs), the next step is to transmit this power through the WPDX right-angle gearbox. Align horizontally so that the keyway of the UDL 2 output goes into perfect engagement with the hollow shaft (input hole) of the WPDX. Use a wrench to tightly lock the entire circle of flange bolts to ensure the machine assembly does not shift or twist under heavy loads.

The 3-stage gear motor (2 UDL 2.2kW and 1 WPDX 120) integrating two UDL speed variators along with the WPDX 120 gearbox not only ensures smooth, jerk-free speed conversion processes but also maintains stable performance for the entire production line.
