Product Description
The AXR series represents the latest generation of multi-purpose rib-cooled motors, integrating decades of professional motor manufacturing experience. It features high power density, flexible configurability and convenient maintainability, setting a new industry benchmark for rib-cooled motors.
Thanks to its superior high power density, the AXR motor can adopt a smaller frame size than traditional motors under the same power output, effectively saving installation space and realizing compact system layout.
The motor adopts a robust cast iron frame with excellent structural stability. It is equipped with standard IC411 cooling system and IP55 protection grade, with optional IC416 cooling and IP66 high-level protection (third-party verified). Covering a maximum power of 1,800 kW and shaft heights of 315 mm to 500 mm, the motor supports both horizontal and vertical installation. It adapts to synchronous speeds of 500–3600 RPM at 50Hz and 60Hz, and fully meets API 541, Shell DEP and other mainstream industrial specifications as well as customized customer requirements.
Mounting Arrangements
- IM B3 (IM 1001)：Standard floor mounting with downward feet for horizontal installation.
- IM V1 (IM 4011)：Flange mounting with downward free shaft end for vertical solid shaft installation.
- IM B35 (IM 2001)：Foot & flange combined horizontal mounting with cylindrical shaft extension and downward feet.
Enclosure & Cooling System
IC411 / IP55 (Standard)
Equipped with an external shaft-driven fan, the motor adopts ambient air for surface circulating cooling. The IP55 protection grade prevents harmful dust accumulation and resists water jets from all directions, ensuring stable operation in conventional industrial environments. Its self-circulating cooling system relies on motor rotation to drive airflow and realize automatic heat dissipation.
IC416 / IP55 (Optional)
Configured with an independent auxiliary cooling fan, it provides stable and efficient heat dissipation for low-speed operation and variable frequency drive working conditions, solving the insufficient cooling problem of self-fan cooling at low speeds.
IP66 Protection (Optional)
The fully enclosed structure achieves complete dust-tight performance and resists strong water jets (12.5mm nozzle) from all directions, suitable for severe dust and heavy water splash working scenarios.
Packaging
Adopts standard export seaworthy packaging, including plywood packaging and fumigated wooden packaging, which is suitable for long-distance sea and land transportation and ensures product safety during transit.
Warranty Period
- Standard Warranty: 12 months after commissioning or 18 months after delivery (whichever comes first)
- Extended warranty service is available upon customer request, please contact us for detailed terms.
