4GG TESLA 4" T motor - 0,55kW - 3x400V - water-powered, two-pole DAB.MOTOR 4GG

Product detailed description

This submersible motor is commonly used in professional heating, plumbing, and irrigation systems where reliable and efficient pump operation is required. It is typically installed in underground or submerged pump stations, such as in boreholes, wells, or sump pits. The motor is designed to operate in environments where water is the primary coolant and lubricant, ensuring long-term durability and performance. Installers working on industrial or commercial water supply systems, drainage solutions, or large-scale irrigation setups will find this motor suitable for integration with 4 inch diameter pumps.

As a two-pole asynchronous motor, it is ideal for applications requiring high-speed operation and stable performance under continuous load. The motor is compatible with both single-phase and three-phase power supplies, making it adaptable to a range of electrical configurations. The installation process involves securing the motor to the pump, ensuring correct alignment, and connecting the power supply through a suitable control system. Proper sealing and insulation are critical to prevent water ingress and ensure safe operation.

Technical parameters

Code	60122748
Brand	IVAR

The motor is rated for 0.55kW and operates on three-phase 400V or single-phase 230V at 50 Hz. The IP68 rating ensures full protection against dust and water immersion, while the F insulation class indicates its ability to withstand high operating temperatures. The NEMA 4 inch flange allows for standardised mounting with compatible 4 inch diameter pumps. These parameters are essential for correct sizing and system compatibility, particularly when selecting matching control units and protection systems.

Installation and connection

Installation begins with verifying the pump and motor compatibility, particularly the flange size and alignment. The motor is connected to the pump using the provided flange and secured with bolts. The four-core flat cable is routed from the motor to the control panel, ensuring that the connection is protected from mechanical stress and water exposure. The cable includes a protective conductor and is terminated via a tight connector above the pump. Installers should ensure that the electrical connections are made in a dry, accessible location and that the motor is grounded correctly. Common mistakes include incorrect cable routing, failure to secure the motor properly, and neglecting to install a suitable control box for single-phase operation.

Compatibility and accessories

This motor is designed for use with 4 inch diameter submersible pumps and requires a compatible control system for operation. For single-phase applications, a control box such as the CONTROL BOX or CONTROL HS system is necessary to provide starting and overload protection. The motor is not self-protected in three-phase configurations and requires external protection from the user. Additional accessories may include sealing compounds, mounting brackets, and electrical enclosures to ensure safe and efficient operation.

Technical background for designers

The motor operates on the principle of a three-phase asynchronous motor, with the rotor supported by radial and thrust bearings. The bearings are lubricated and cooled by the surrounding water, eliminating the need for external cooling systems. The stator is housed in a stainless steel casing filled with argon-based gas to prevent corrosion and ensure long-term insulation. The use of AISI 304 stainless steel for mechanical components ensures resistance to corrosion and mechanical stress. The motor is integrated into the system via a standard NEMA flange and is designed to operate continuously under submerged conditions. The service life and efficiency of the motor depend on proper installation, correct alignment, and the use of appropriate control and protection systems.

Service and operation

Regular inspection of the motor should include checking the integrity of the sealing system, the condition of the electrical connections, and the alignment of the pump and motor assembly. The motor does not require scheduled maintenance beyond these checks, as the bearings are lubricated by the surrounding water and do not require additional servicing. Any signs of vibration, unusual noise, or electrical faults should be investigated immediately. The motor should be removed and inspected if it is suspected of being damaged or if performance issues arise.

Frequently asked questions

Can the motor be used with a single-phase power supply?
Yes, the motor can be connected to a single-phase 230V supply, but it requires a control box with a starting capacitor and overload protection for safe operation.

Is the motor self-protected against overload?
No, the motor is not self-protected in three-phase configurations. External protection must be provided by the user, while single-phase operation requires a control box with overload protection.

What type of cooling does the motor use?
The motor is cooled by the surrounding water, which also serves as the lubricant for the bearings. No additional cooling system is required.

Can the motor be used with non-4 inch diameter pumps?
No, the motor is specifically designed for 4 inch diameter pumps and requires the NEMA flange for secure mounting.
