Product Overview
The AXR series represents the latest generation of multipurpose rib-cooled motors, designed to offer high power density, easy configurability, and built-in serviceability. Incorporating years of manufacturing experience, these motors set a new industry benchmark by delivering more watts per kilogram than previously achieved with rib-cooled designs.
Key Benefits:
- High Power Density: Allows for the use of a motor one frame size smaller than conventional products for a given output, saving space and enabling compact installations.
- Compliance: Meets main industry standards such as API 541 and Shell DEP, as well as specific customer requirements.
- Rugged Construction: Features a durable cast iron frame suitable for harsh environments.
Technical Features
- Cooling & Protection: Standard configuration includes IC411 cooling and IP55 protection. Optional IC416 cooling is available for low-speed applications (especially with variable speed drives), and IP66 protection is verified by independent testing organizations.
- Performance Range: Covers outputs up to 1,800 kW with shaft heights from 315 to 500 mm. Technical data is available for synchronous speeds from 500 to 3600 rpm at both 50 Hz and 60 Hz.
- Versatility: Capable of both horizontal and vertical mounting.
Mounting Arrangements
Standard mounting configurations include:
- IM B3 (Code II: IM 1001): Standard floor mounting with feet facing downwards (horizontal foot mounted).
- IM V1 (Code II: IM 4011): Flange and free shaft end facing downwards (vertical solid shaft, flange mounted).
- IM B35 (Code II: IM 2001): Foot-and-flange mounted horizontal configuration, with the flange part of the end-shield, one cylindrical shaft extension, and feet facing downwards.
Enclosure and Cooling Details
- IC411 / IP55 (Standard): Uses an external shaft-mounted fan to circulate surrounding air for cooling. The enclosure protects against dust ingress and water jets from any direction.
- IC416 / IP55: Utilizes an additional motor to drive the cooling fan, ensuring required cooling for low-speed applications.
- IP66 Protection: Provides a completely dust-tight enclosure and protection against powerful water jets (12.5 mm nozzle) from any direction.
- Cooling Principle: The primary coolant circulates in a closed circuit within the motor, transferring heat through the external ribbed surface to the surrounding medium via self-circulation dependent on rotational speed.
Packaging and Warranty
- Packaging: Export-standard seaworthy packages, including plywood or wooden fumigation packages, suitable for long-distance transportation by sea or land.
- Warranty: Standard warranty covers 12 months after commissioning or 18 months after delivery, whichever comes first. Extended warranty periods are available upon request.
