4GX TESLA 4" T motor - 1,5kW - 3x400V - double pole DAB.MOTOR 4GX

Product detailed description

This IVAR 4GX TESLA 4 inch motor is suitable for submersible applications in heating, plumbing, and irrigation systems. It is commonly used in deep well or sump environments where a high-torque, durable motor is required. The motor is designed for integration into closed-loop systems and is often found in industrial and commercial buildings, including factories, warehouses, and large residential complexes. Installers typically work with this motor in conjunction with submersible pumps, ensuring proper alignment, sealing, and electrical connections to maintain system integrity and operational safety.

The motor is built to operate under continuous load conditions and supports both single-phase and three-phase configurations depending on the system requirements. Its compact design and robust construction make it suitable for submerged environments where corrosion resistance and mechanical stability are critical. The motor’s double pole configuration allows for efficient starting and operation, particularly in systems with high inertia or heavy startup loads.

Technical parameters

The technical parameters define the motor’s suitability for specific applications. The 1.5kW power rating indicates the maximum mechanical output available for driving pumps or other equipment. The 3x400V three-phase input is ideal for larger installations where balanced phase supply is available. The motor’s double pole configuration ensures smooth acceleration and stable operation under load. These parameters are essential for determining compatibility with existing infrastructure and for selecting appropriate control systems such as starters or protection units.

Installation and connection

Installation begins with verifying the motor’s compatibility with the pump and the electrical supply. The motor must be securely mounted and aligned with the pump shaft to prevent mechanical stress. The flange connection (NEMA standard) should be checked for correct fit and sealing. The flat four-core cable exiting the motor must be connected to the power supply using a tight, waterproof junction. A control box or starter unit should be selected based on whether the motor operates in single-phase or three-phase mode. Common installation errors include incorrect alignment, poor cable termination, and failure to secure the motor flange properly, all of which can lead to vibration, leaks, or electrical faults.

Compatibility and accessories

This motor is compatible with submersible pumps and systems requiring a 4 inch flange connection. It works with single-phase and three-phase configurations, depending on the selected control unit. Additional components such as the CONTROL BOX or CONTROL HS system are recommended for managing motor startup and overload protection. Installers should also ensure that the power supply matches the motor’s voltage and frequency requirements. No alternative products are listed for direct comparison in this category.

Technical background for designers

The motor operates on asynchronous principles, converting electrical energy into rotational motion through electromagnetic induction. The rotor is supported by radial plain bearings and an axial thrust bearing, all lubricated and cooled by the surrounding liquid. The stator is housed in a stainless steel casing filled with inert gas, ensuring long-term insulation and protection against environmental factors. Integration into a system requires careful consideration of hydraulic load, flow rate, and power supply characteristics. Factors such as water quality, temperature, and mechanical stress affect the motor’s lifespan and efficiency over time.

Service and operation

Regular inspection of the motor’s electrical connections and sealing integrity is essential for ongoing performance. Any signs of vibration, unusual noise, or overheating should be investigated promptly. The motor does not require scheduled maintenance intervals beyond these visual checks. However, periodic testing of the control system and overload protection is recommended, especially in high-demand applications. The motor should be removed and inspected if the system experiences repeated failures or drops in performance.

Frequently asked questions

Can the motor be operated in single-phase mode?
Yes, the motor supports single-phase operation when used with an appropriate control box containing a start capacitor and overload protection.

Is the motor compatible with 3x230V supply?
Yes, the motor is designed to work with both 3x230V and 3x400V three-phase supplies, depending on the system configuration.

How is the motor cooled during operation?
The motor is cooled by the surrounding liquid, which circulates around the bearings and housing to dissipate heat.

What type of cable is used for the electrical connection?
A flat four-core conductor is used to connect the motor to the power supply, with an integrated connector for secure and watertight termination.
