The 700 rpm electric motor in the H17R 450-B-8-6 design delivers compact power for technologies where smooth starting, stable load and long operating endurance are expected from the drive. This high-voltage electric motor with an output of 560 kW is designed for 6 kV industrial drives where reliable continuous operation and precise interaction between the motor and the technological system are decisive.
Copper rotor helps maintain performance under long-term load
Copper strip in the rotor cage limits rotor losses and at the same time better withstands thermal stress during repeated duty cycles. In practice, this helps maintain stable machine behavior even in demanding applications where the drive is exposed to long-term loads without unnecessary outages. For operators of large factories, it is important that the solution supports a long service life and reduces the need for frequent maintenance interventions.
IE4 efficiency reduces operating demands
The motor belongs to the category of three-phase electric motor with an efficiency of 95,6 %, which at this power level is particularly important in long-running applications and drives that operate practically continuously. The IE4 Super Premium efficiency class supports more economical operation and reduces energy losses in applications where the cost of every kilowatt-hour is monitored. Such a solution makes particular sense when powering a large technological system and every percentage point of efficiency affects the economics of the line.
Speed and torque for large technological systems
Rated speed of 743 rpm together with rated torque of 7198 Nm provides a suitable basis for applications in which the drive must deliver reliable traction while maintaining a controlled load profile. An eight-pole electric motor in this category fits well into machines where lower speed is required without unnecessary overloading of the gearbox.
- Mills for processing mineral raw materials.
- Rolling lines for heavy metallurgical operations.
- Main extraction fans in steelworks.
- Compressor stations for process gas.
- Circulation pumps in the energy industry.
- Conveyors with continuous feeding of bulk materials.
- Aggregate crushers in quarries.
- Mixing units in chemical production.
Motor protection helps in dusty and humid environments
For technological areas with dust, condensation or increased humidity, it is crucial that the motor maintains stable parameters even outside ideal conditions. Therefore, this drive is used in configurations with protection suitable for demanding environments, selected in practice according to the type of operation and the level of environmental exposure. A weight of 5300 kg and robust frame construction also support secure installation in heavy technological systems.
Accessories simplify motor monitoring
For more precise operating monitoring, 6xPT100 in the winding, 1xPT100 in the NDE bearing, 1xPT100 in the DE bearing, an anti-condensation heater and 3xPTC thermistor are available. Such equipment helps service teams assess temperature conditions more quickly, protect the winding during starts and plan maintenance more effectively according to the actual load.
