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

The 3-Stage Gear Motor (2 UDL 1.5kW and 1 WPDO 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. Thanks to the continuous three-stage reduction structure, the device delivers extremely low output speed, high torque, and stable performance under prolonged heavy-duty conditions.

Overall design of the 3-Stage Gear Motor (2 UDL 1.5kW and 1 WPDO 100)

The 3-Stage Gear Motor (2 UDL 1.5kW and 1 WPDO 100) is developed based on industrial mechanical standards, ensuring durability, stability, and high load capacity. The three reduction stages are clearly divided in order: input mechanical speed variator UDL stage → intermediate UDL stage → final WPDO stage. The housing of the motor and gearbox is manufactured from cast iron or solid die-cast aluminum alloy, providing good heat dissipation, corrosion resistance, and a long service life in industrial environments.

Detailed structure of the 3-stage gear motor

The 3-Stage Gear Motor (2 UDL 1.5kW and 1 WPDO 100) is a gear motor line 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 WPDO 100) with detailed structure as follows:

Electric motor structure:

• Cast iron or die-cast aluminum motor housing, durable with good heat dissipation.
• Electrostatic powder coating over the entire body, increasing corrosion resistance.
• 100% copper winding, good heat resistance during continuous operation.
• Dynamically balanced squirrel-cage rotor, helping the motor run smoothly and reducing vibration.
• Hardened steel shaft, excellent torsional load and wear resistance.
• High-quality bearings, helping the equipment operate stably for a long time.

Gearbox structure:

• Stage 1 is the mechanical speed variator (UDL): Specifically, the 1.5kW 2Hp mechanical speed variator consisting of friction disc – cone disc assembly, input – output shafts, and adjustment knob, allowing stepless speed variation before entering the gearbox.
• Stage 2 is the 2-stage gearbox: Specifically, the UDL 1.5kW – WPDO 100 2-stage gearbox creating a large gear ratio and high torque, operating smoothly.

Applications of the 3-Stage Gear Motor (2 UDL 1.5kW and 1 WPDO 100)

The 3-Stage Gear Motor (2 UDL 1.5kW and 1 WPDO 100) is widely applied in many industrial fields:

• Agitators, thick or high-viscosity material mixers
• Low-speed conveyors, heavy-duty conveyors
• Industrial dosing – feeding systems
• Food production, packaging, wood, and plastic processing lines
• Continuously operating mechanical machines
• Systems requiring high torque and stable 24/7 operation

How to install an electric motor with 2 UDLs and 1 WPDO to form a 3-stage gear motor

• Step 1: Complete assembly 1 (Connecting the motor – first UDL)
  • Align the center line carefully to push the electric motor shaft deep into the flange hole of the first UDL mechanical speed variator.
  • Use specialized tools to tighten the connection points, completely preventing misalignment that causes humming noises during operation.
• Step 2: Complete assembly 2 (Doubling the speed variator assembly)
  • Take the newly assembled assembly 1, connect its output shaft directly to the power-receiving flange of the second UDL unit.
  • Secure this assembly thoroughly. Two connected UDL units will work together smoothly to reduce rotational speed down to the desired extremely low level.
• Step 3: Integrate the final assembly (Connecting with the WPDO gearbox)
  • Install the completed speed variation system into the WPDO gearbox.
  • Carefully rotate the shaft so that the keyway matches precisely with the shaft hole of the WPDO. Tighten the bolt ring to eliminate any twisting risks during power transmission to the vertical shaft.

Integrating two UDL speed variator stages along with the WPDO 100 gearbox creates an ideal 3-stage drive system, providing ultra-slow speed control capability with maximum torque for agitators or heavy-duty conveyors.
