H17R 450-A-8-6 with an output of 500 kW delivers high power density in a solution prepared for 6 kV operation. This 700 rpm electric motor is designed for applications where stable traction, low losses and reliable continuous operation are decisive. In practice, this means reserve capacity for large technological systems as well as sensible use of space in the machine room.
700 rpm electric motor in a compact 6 kV design
The compact 6000 V electric motor is suitable where the drive must deliver full output within a frame corresponding to sizes H315 to H560. A three-phase electric motor with this concept reduces installation requirements and facilitates drive design in production lines, pumping stations and heavy process technology. For the operator, this means less intervention in the existing layout without compromising drive effectiveness.
Copper rotor for long service life in demanding operation
The copper rotor made of copper alloy helps limit losses and increases thermal resistance during long-term loading. This benefits the energy efficiency of the entire drive, especially in applications where the motor operates at high load for most of the shift. For OEM manufacturers and industrial operators alike, predictable thermal management is important, supporting longer service intervals and more stable performance over time.
Advanced temperature monitoring for control of bearings and winding
Integrated advanced temperature monitoring uses sensing in the winding as well as at the bearing points, allowing operators to detect rising temperature early and respond before it results in downtime. This configuration includes 6 x PT100 in the winding, 1 x PT100 in the NDE bearing, 1 x PT100 in the DE bearing, an anti-condensation heater and 3 x PTC thermistor, increasing control during starting, loading and shutdown. For projects with long cycles and high monitoring requirements, this equipment is a practical benefit.
Bearings and efficient starting in large technological systems
6328-C3 bearing arrangement on both the DE and NDE sides supports smooth operation under higher loads and helps keep the motor running in a stable mode. A starting current ratio of 4,6 % and efficiency of 95,5 % give the operation room for sensible sizing of the power supply and control of operating costs. Rated torque of 6435 Nm, rotor moment of inertia of 19,0 kg·m², rated current of 61,7 A, power factor of 0,82, insulation class F, temperature rise B, weight of 5100 kg, copper strip in the rotor cage, starting torque of 0,9 % and breakdown torque of 2 % confirm that this is a solution for demanding technological systems.
Applications where reliable performance is decisive
This model is suitable for stone crushers, raw-material mills, belt conveyors for bulk materials, fans for main technological systems, centrifugal pumps for cooling circuits, compressor stations, extruders, mixers for chemical compounds, drum dryers and rolling lines.
