H27R 4501-8-6 provides operations with high loads with scope for noticeably lower energy losses and more stable operating economics. This 700 rpm electric motor with an output of 560 kW is designed for systems where efficiency, reliable starting and long-term drive availability are decisive. In the HV drive category, reduced energy loss during continuous operation lowers operating costs while improving the balance of the entire technological unit.
The H27R-HD-Modular series design uses IE4 Super Premium efficiency, which helps limit unnecessary thermal losses at high outputs. The welded steel frame increases assembly rigidity while facilitating handling during transport and installation in confined production spaces. For operators in drive technology, standard thermal protection and monitoring are also important, so motors in this series are prepared for supervision of both the winding and bearings.
Efficiency and robustness for long operation
In this three-phase electric motor, rated current of 67,8 A and a power factor of 0,84 are matched to high-power networks where both power-supply stability and precise protection design matter. Insulation class F together with temperature rise class B supports reliable reserve during operation in demanding technological units. Combined with a package weight of 4560 kg and robust frame construction, the motor is suitable for integration into large linear and rotary systems.
- Rated torque of 7208 Nm provides sufficient force for heavy starts and steady load.
- Starting torque reaches 0,7 times the rated torque and breakdown torque 1,8 times the rated torque when designing torque reserve.
- Starting current reaches 4,5 times the rated current, which is important when designing power supply and protection components.
- Rotor inertia of 42,0 kg·m² helps provide predictable behavior during starting.
- Load inertia of 1530,0 kg·m² allows suitability for massive process assemblies to be assessed.
Precise mounting for high loads
The bearing arrangement is designed for long service life under high axial and radial demands. NU228-C3+6030-C3 is used on the DE side and NU228-C3 on the NDE side, supporting stable operation under continuous load and precise installation of the connection to gearboxes or directly to the driven machine. For motors with a 6000 V voltage rating, this level of mechanical reliability is key to long-term operation without unnecessary downtime.
Use in industrial units
H27R 4501-8-6 is used in mill lines, compressor stations, fan fields, pumping units, conveyor systems and drives for mixing and crushing technologies. In each of these applications, precise sizing at 742 rpm helps stabilize the process and simplify connection to technology with high inertia.
Solution for OEMs and large operations
H27R 4501-8-6 is suitable for OEM manufacturers of large technological units who need to combine efficiency, robustness and predictable servicing in one drive. The H27R-HD-Modular series can be integrated into new assemblies and modernizations where long service life, lower energy demand and safe starting under demanding conditions are monitored.
