3-Stage Gear Motor (2 UDL 0.8kW and 1 WPDS 70)

The 3-Stage Gear Motor (2 UDL 0.8kW and 1 WPDS 70) is a gear motor assembled from an electric motor-specifically a 3-phase electric motor-combined with a gearbox-specifically a 3-stage gearbox-allowing stepless speed adjustment from high to extremely low speeds. After adjustment, the transmission force is further reduced deeply through the WPDS 70 worm gearbox, which features an eccentric output shaft design to steadily increase torque. All three reduction stages coordinate smoothly to produce a slow, steady output speed without jerking, ensuring the equipment operates smoothly in continuous production environments.

Overall design of the 3-Stage Gear Motor (2 UDL 0.8kW and 1 WPDS 70)

The 3-Stage Gear Motor (2 UDL 0.8kW and 1 WPDS 70) helps expand the speed adjustment range, allowing smooth speed changes without load shock. It plays the role of final speed reduction, generating high and stable torque with a characteristic eccentric shaft design, suitable for machinery with special transmission directions. Constructed from cast iron or pure aluminum, the outer casing is coated with electrostatic paint to prevent scratches during operation.

Detailed structure of the 3-Stage Gear Motor (2 UDL 0.8kW and 1 WPDS 70)

The 3-Stage Gear Motor (2 UDL 0.8kW and 1 WPDS 70) is assembled from a 3-phase 0.8kW 1Hp electric motor and a 3-stage gearbox (2 UDL 0.8kW and 1 WPDS 70). Its detailed structure is as follows:

Electric motor structure:

• Motor housing: Designed with vertical ribs to increase the heat dissipation surface area to the environment, usually cast from aluminum alloy or cast iron depending on the production batch, helping dissipate heat well when running under heavy loads.
• Rotor: The centered rotating shaft, pressed from high-magnetic technical steel sheets, ensures uniform rotation.
• Stator: The stationary magnetic part, with the magnetic core wound from pure copper wire capable of withstanding high temperatures.
• Terminal box: Contains the power terminal block, equipped with a waterproof and dustproof rubber gasket to meet the IP55 protection standard.
• Motor rear end: Integrates a cooling fan and protective cover, maintaining a safe temperature level for the motor during continuous operation.

Gearbox structure:

• Stage 1 is the Mechanical Speed Variator (UDL), specifically the Motor 0.8kW 1Hp Mechanical Speed Variator: Consists of friction disc – cone disc assemblies, input-output shafts, and an adjustment knob, allowing stepless speed changes before entering the gearbox.
• Stage 2 is the 2-stage gearbox, specifically the 2-stage UDL 0.8kW – WPDS 70 gearbox consisting of a hardened steel worm and a bronze worm gear, creating a large transmission ratio and high torque, operating smoothly.
• Driving motor 0.8kW: 3-phase motor with copper wire stator and dynamically balanced rotor, providing stable traction force for the entire 2-stage system.

Applications of the 3-Stage Gear Motor (2 UDL 0.8kW and 1 WPDS 70)

With the characteristic of producing extremely slow rotational speed, strong traction force, and adjustable capability, this 3-stage gear motor assembly is applied in:

• Drying conveyor systems, small drip-feed conveyors with fair loads in the food processing industry.
• Chemical stirrers, medium-capacity microbial fermentation tanks requiring slow and even mixing speeds.
• Rotation mechanisms of various kilns, industrial egg incubators, agricultural product drying equipment.
• Winding machine systems, nylon film and fabric take-up/pay-off machines requiring precise tension control.

Guide on how to install an electric motor with 2 UDLs and 1 WPDS

To assemble an electric motor with 2 UDL speed variator units and 1 WPDS gearbox, the correct procedure must be followed to ensure that the drive assemblies connect accurately, transmit stable torque, and operate durably over the long term.

Step 1: Install the electric motor into the first UDL

Insert the shaft of the electric motor into the input of the first UDL unit, while checking the concentricity between the shaft and the flange. Once the parts are correctly positioned, tighten all bolts evenly to create a secure connection and minimize vibration during operation.

Step 2: Connect the second UDL unit

Continue connecting the output of the first UDL to the input of the second UDL. Align the assembly positions, check the rotation capability of the shaft, and then tighten all bolts so that the speed variator assembly operates stably.

Step 3: Install the drive assembly into the WPDS gearbox

Bring the assembly consisting of the electric motor and the two UDLs into the WPDS gearbox. Adjust the keyway, shaft, and flange to mesh completely before securing with bolts. After completion, recheck all joints and manually test rotation to ensure the drive system operates smoothly.

The combination of two UDL speed variator units and the WPDS gearbox creates a 3-stage drive system capable of deep speed reduction, maintaining large torque, and effectively meeting applications requiring low speed and high load such as mixers, conveyors, blenders, presses, and various other industrial equipment.
