WPDO 120 Gear Motor 4kW 5.5Hp

The WPDO 120 Gear Motor 4kW 5.5Hp is a device used to reduce rotational speed and increase transmission force in mechanical systems. The gear motor device consists of two components: an electric motor and a worm gearbox, suitable for heavy-load applications requiring long-term stable operation.

Overview of WPDO 120 Gear Motor 4kW 5.5Hp design

The device uses a 3-phase electric motor to generate initial rotational movement, which is then transmitted through the worm gear mechanism to reduce speed and increase torque. This arrangement helps the system achieve stable performance and reduces vibration during operation. In some cases, it can be replaced with a 1 phase gear motor or a 3 phase gear motor if using residential power.

The gearbox housing is solidly cast from cast iron, ensuring load-bearing capacity and protecting internal components when working in industrial environments.

Detailed structure of WPDO 120 Gear Motor 4kW 5.5Hp

This section presents the main components to help users clearly understand how the device generates and transmits motion.

3-Phase Electric Motor 4kW 5.5Hp:

• Stator winding: Placed in the electrical steel core, consisting of many insulated copper turns. When powered, the winding creates a continuous rotating magnetic field, which is the main factor generating rotor motion.
• Rotating rotor: Consisting of conductor bars and short-circuit rings, tightly mounted on the shaft. When subjected to the stator magnetic field, the rotor rotates accordingly and generates output torque.
• Cooling fan: Mounted at the rear of the motor, rotating with the shaft to generate cooling airflow, helping maintain a stable temperature when the device operates continuously for a long time.

WPDO 120 worm gearbox

• Worm shaft: Having a helical thread shape, machined from alloy steel and surface heat-treated. When rotating, the worm shaft exerts thrust on the worm gear while determining the gear ratio of the system.
• Worm gear: The component that meshes directly with the worm shaft, usually made of brass to reduce friction. The worm gear rotates slower but generates greater output torque.
• Oil seal: Installed at the input and output shaft positions, helping retain lubricating oil inside the gearbox while preventing dust and water from entering from the external environment.

Instructions for installing the WPDO worm gearbox onto a 3-phase electric motor

Assembling the WPDO gearbox with a 3-phase electric motor must be performed correctly according to technical standards to ensure stable transmission performance, reduce vibration, and enhance equipment durability.

Step 1: Inspect components

Before installation, fully inspect the gearbox, electric motor, shaft, keyway, and included accessories. At the same time, thoroughly clean the contact surfaces to minimize dust or foreign objects affecting the assembly process.

Step 2: Check compatibility

Compare the motor shaft size with the gearbox bore hole. Check the flange, installation distance, and related specifications to ensure the parts can connect accurately.

Step 3: Perform assembly

Install the motor shaft straight into the gearbox, aligning the key and keyway in the correct position. Avoid using excessive force if the parts do not fully engage. Users can refer to the gear motor video to directly observe the steps for installation, alignment, and system inspection before operation.

Step 4: Tighten and test run

After assembly, tighten the bolts in a symmetrical order to ensure force is evenly distributed across the joint surfaces. Conduct a no-load test run and monitor vibration, noise, or abnormal signs before putting the equipment into official operation.

To better understand the structure, operating principle, and usage notes, users can refer to additional videos related to the WPDO gearbox and 3-phase electric motor. These contents help supplement practical knowledge as well as troubleshooting experience for common issues.
