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

The 3-Stage Gear Motor (2 UDL 2.2kW and 1 WPDO 120) features a compact and balanced appearance, coupled from two UDL speed variators and a WPDO 120 gearbox in an integrated assembly. The input section is a 2.2kW electric motor with an aluminum or cast iron housing machined as a single piece with cooling ribs, creating a robust feel and increasing durability during continuous operation.

Detailed Structure of the 3-Stage Gear Motor

The 3-Stage Gear Motor (2 UDL 2.2kW and 1 WPDO 120) is a gear motor 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 WPDO 120) with the following detailed structure:

Electric Motor Structure:

• Motor housing: made of cast iron or aluminum, protecting internal parts and assisting with heat dissipation.
• Stator: core steel and coils creating a magnetic field when energized.
• Rotor & rotating shaft: moving part receiving force from the stator to transmit outward.
• Cooling fan & bearings: keep the shaft rotating smoothly, reduce heat, and increase durability during continuous operation.

Gearbox Structure:

• Stage 1: Mechanical speed variator (UDL), specifically a 2.2kW 3Hp motor speed controller with a cast iron housing protecting the transmission and containing lubricating oil.
• Stage 2: 2-stage gearbox, specifically a UDL 2.2kW – WPDO 120 2-stage gearbox with a cast aluminum housing: lightweight, good heat dissipation, and standard connecting flange.
• Friction disc system: changes the gear ratio for stepless speed adjustment.
• Speed adjustment knob: allows smooth adjustment and direct speed changes while the machine is running.

How to Assemble an Electric Motor with 2 UDL and 1 WPDO to Form a 3-Stage Gear Motor

Below is the guide on assembling an electric motor with 2 UDL and 1 WPDO to form a 3-stage gear motor from Thanh Thai Motor:

• Step 1: Couple the Electric Motor with UDL 1
  • Insert the electric motor shaft to fit into the female shaft hole (input) of the first UDL speed variator.
  • Align concentrically, press the flange tightly, and use a wrench to tighten the fixing bolts.
• Step 2: Install UDL 2 (Create Dual Speed Variator Assembly)
  • Connect the output shaft of UDL 1 directly into the input hole of UDL 2.
  • Securely lock the flange connecting bolts between the two devices to form a monolithic variable speed motor assembly.
• Step 3: Integrate the Assembly (Motor + 2 UDL) into the WPDO Gearbox
  • Accurately align the keyway, and fit the output shaft of UDL 2 into the hollow shaft of the WPDO gearbox (a characteristic gearbox series with the load shaft pointing upward).
  • Ensure the flange fits tightly without shaft distortion, then completely tighten all screws.

The 3-Stage Gear Motor (2 UDL 2.2kW and 1 WPDO 120) allows businesses to easily install it into various complex machinery systems without taking up too much space. The speed adjustment knob is scientifically arranged, helping operators smoothly fine-tune the working tempo of the agitator and eliminate any unnecessary jerking impact forces.
