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

The 3-Stage Gear Motor (2 UDL 2.2kW And 1 WPDA 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-creating a powerful drive system with stepless speed adjustment capabilities and high traction force. The three-stage reduction design ensures stable operation, low speed, and high torque, making it ideal for heavy-duty applications or operations requiring continuous speed variations.

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

The 3-Stage Gear Motor (2 UDL 2.2kW And 1 WPDA 120) features a monolithic cast iron housing with stiffening ribs and a signature blue-gray industrial paint finish. The right-angle output shaft design allows for easy installation in tight spaces while enhancing load-bearing capacity thanks to the internal worm gear drive. The exterior surfaces are coated with anti-rust electrostatic paint, protecting the motor from environmental impacts and extending its lifespan. The overall design is both robust and aesthetically pleasing, well-suited for industrial systems requiring high stability.

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

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

Electric Motor Structure:

• Motor Housing: Cast from monolithic cast iron with large vertical fins, ensuring optimal heat dissipation and excellent shock and vibration resistance during continuous heavy-duty load pulling.
• Rotor: Large centered rotating shaft pressed from high-magnetic technical steel sheets, precisely dynamically balanced for powerful power transmission.
• Stator: Magnetic core wound from large cross-section pure copper wire, with Class F insulation to withstand high temperatures at maximum operating intensity.
• Terminal Box: Houses a large power terminal block, equipped with waterproof rubber gaskets and tightly secured cable outlets, meeting the IP55 dust and water protection standard.

Gearbox Structure:

• Stage 1:Mechanical speed variator (UDL)-specifically a 2.2kW 3Hp mechanical speed variator-consisting of helical friction steel discs that change position to continuously adjust the output speed.
• Stage 2:2-stage gearbox-specifically a 2.2kW UDL – WPDA 120 2-stage gearbox-featuring a consecutive two-stage reduction drive for deeper reduction and higher torque compared to standard 1-Stagegearboxes.
• Gearbox Housing: Made of cast iron or cast steel, protecting the transmission system and holding lubricating oil.
• Output Shaft – Bearings – Oil Seals: The output shaft transmits power, bearings ensure smooth rotation, and oil seals keep lubricating oil securely contained.

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

To install an electric motor with 2 UDLs and 1 WPDA, follow the correct sequence to ensure secure device connections and concentric shaft alignment.

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

Insert the electric motor shaft into the flange of the first UDL speed variator, ensuring precise alignment between the shaft and hole center. Then evenly tighten the bolts for a secure connection, helping the drive assembly operate stably and reducing vibration during use.

Step 2: Connect the second UDL unit

Install the output of the first UDL into the input of the second UDL. Check the concentricity between the two variators, then secure the connection points. The dual-UDL in-series configuration helps expand the speed adjustment range before transmitting power to the gearbox.

Step 3: Install the drive assembly onto the WPDA gearbox

Proceed to couple the entire motor and dual-UDL assembly with the WPDA gearbox. Align the keyway and flange properly, rotating the shaft slightly if necessary to ensure all components engage completely. Finally, tighten all bolts with appropriate torque to ensure stable torque transmission.

The combination of the two UDL speed variators and the WPDA gearbox forms a 3-stage drive system capable of flexible speed adjustment while increasing output torque. This configuration is suitable for applications requiring low speed and heavy loads such as agitators, conveyors, mixers, and various other industrial equipment.
