This document is a catalog of low voltage water cooled motors produced by ABB Motors and Generators. These motors utilize water cooling for efficient heat dissipation and high output power. They are suitable for various applications including marine, water pumping, printing machines, and wind turbine generators.
The catalog describes ABB's low voltage water‑cooled motor range, which is optimized for variable‑speed and constant‑torque applications such as marine drives, water‑pumping, printing machines, and wind‑turbine generators. It outlines the mechanical design, cooling concepts, and the efficiency classification (IE2) of the motors.
Detailed technical data are provided, including frame sizes, power output, voltage ratings, degree of protection (IP55), cooling‑water requirements, terminal box configurations, and ordering codes. The document also contains dimension drawings, rating plate information, and variant codes for different mounting options. This manual is written in Chinese.
| IEC frame sizes | 280 to 450 |
|---|---|
| Efficiency class | IE2 |
| Degree of protection (standard) | IP55 |
| Maximum cooling water pressure | 5 bar |
| Output power range | 0.75 to 375 kW |
| Rated voltage | Up to 1000 V |
The standard protection class is IP55.
The cooling water pressure must not exceed 5 bar.
