Product Introduction
The WPX 135 Gear Motor 4kW 5.5Hp provides efficient speed reduction, increased pulling force, and stable operation for mechanical systems. The product is widely applied in various modern industries.
Thanh Thai Motor offers special policies and discounts for dealers and bulk purchasers. We are ready to provide in-depth technical consultation and fast nationwide delivery.
The WPX 135 Gear Motor 4kW 5.5Hp is a gear motor combined from an electric motor-specifically a 3-phase electric motor-and a gearbox, namely a worm gearbox. This worm gear motor helps reduce the rotational speed of the motor while increasing pulling force and enhancing operational productivity.
The exterior structure of the WPX 135 Gear Motor 4kW 5.5Hp is made of cast iron or aluminum housing, coated with electrostatic paint to increase aesthetics and prevent scratches during operation.
The rotating shaft of the device is machined from refined steel at high temperatures, with a smooth polished surface, high heat resistance, and heavy load capacity, delivering stable and smooth power transmission.

The 3-phase electric motor consists of basic components such as:


Evaluating the suitability of the WPX 135 5.5Hp gear motor for production lines requires high mechanical precision. Please refer to the standard technical measurement data table provided by the manufacturer below.
The selection of switching devices and power supplies depends entirely on the specifications of the 3-phase electric motor 4kW 5.5Hp integrated into the gear motor unit.
