Product catalog summary

Model Overview: The D5U model is a high-power motor with capabilities up to 240 kW and voltages up to 690 V. It is designed for use in hazardous environments with ATEX protection (Ex de I Mb) and is suitable for various industrial applications such as compressors, conveyor systems, cranes, and pumps.

Specifications: The motor is available in frame sizes 160 to 315 and offers 2, 4, 6, and 8 pole configurations. It features a Totally Enclosed Fan Cooled (TEFC) enclosure with cooling options IC 411 and IC 416. The degree of protection ranges from IP 55 to IP 65.

Construction and Materials: The housing and shield are made from cast iron (EN 1561-GJL-200 or better), while the shaft is constructed from carbon steel (EN 10083-2 C45 or better). The main terminal box is also cast iron, and the fan is made from thermoplastic reinforced with glass fibers or metallic materials.

Cooling System: The standard cooling system is IC 411, with an option for IC 416 for variable speed applications. The system involves frame surface cooling and self-circulation of primary and secondary coolants.

Certificates and Testing: The motors are certified by CESI and comply with IEC/EN 60079-15 and ATEX directive 94/9/EC. Mechanical vibrations meet EN 60034-14 standards.

Components: The stator/rotor core is laminated and enamel-insulated to minimize eddy current losses. The rotor is a short circuit type, with options for aluminum or copper bar construction. Bearings are designed for durability, with options for regreasable bearings in larger frame sizes.

Impregnation and Insulation: The stator is treated with an unsaturated polyester amide resin and insulated with F class synthetic enamel, with H class available on request.

Optional Features: The motor can be customized with reinforced insulation for frequency converters, dual/multiple winding configurations, special shaft ends, increased protection degrees, encoders, vibration sensors, and insulated bearings.
