High-voltage electric motor 560 kW, 990 rpm, 6 000 V, H17R 400-D-6-6

In metallurgy, cement plants, water management and heavy process manufacturing, the drive determines whether a line remains in a stable operating mode or loses output with every start. The 900 rpm electric motor in the H17R 400-D-6-6 version with an output of 560 kW is designed precisely for such use, where compact power, long-term operational reliability and space efficiency within the technology are required. In the VYBO Electric range, it is a solution for operations that need starting reserve, reasonable losses and a design prepared for prolonged loading.

Copper rotor for long service life in heavy-duty operation

The copper rotor provides the greatest value in real operation because the copper alloy reduces rotor losses and also handles thermal load better during repeated starts. During long production cycles, this design results in less overheating, more stable torque transmission and lower wear of components exposed to continuous operation. For operators of large factories, this means fewer interventions in the line and better scope for maintenance planning.

The design with a 400 mm frame size gives the motor a firm basis for integration into technological units requiring precise installation and resistance to vibration. A three-phase electric motor in this class fits well into drives that operate with frequent starts, changing loads or long operating hours. From the perspective of OEM manufacturers, the option to adapt the supply to the specific grid is also important because the model is prepared for voltage levels of 3 300 V, 6 000 V, 10 000 V and 11 000 V.

IE4 Super Premium for lower losses and greater operating discipline

IE4 Super Premium efficiency supports energy efficiency wherever the drive operates daily under demanding conditions and every kilowatt-hour saved reduces operating costs. Combined with a rated current of 65,5 A and power factor of 0,86, the motor helps maintain a sensibly designed electrical system while providing reserve capacity for technological peaks. For plants with high utilization, this is a practical tool for improving the overall economics of production.

HV electric motors in this category are often used for pumps, fans, mills and other units where requirements for continuous load and thermal resistance are above average. This high-voltage electric motor maintains power reserve even during long operation because its rated speed of 990 rpm and rated torque of 5402 Nm support even energy transmission to the driven machine. In practice, this results in calmer operation of the technology and lower mechanical stress on downstream units.

Balanced starting for operations with high load capacity

Motor starting takes into account the requirements of large drives where not only the rated state but also behaviour during start-up is important. Starting and breakdown torque ratios together with starting current provide designers with data for precise sizing of switchgear, protection and the transmission system. A 6-pole electric motor in this version therefore fits well into applications requiring controlled starting without unnecessary mechanical shocks.

Readiness for condition monitoring is also important for service teams. 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 a 3 x PTC thermistor are available, simplifying temperature supervision and reducing the risk of unplanned shutdowns. We are the largest company in our sector in Central Europe, which in large projects is also reflected in the ability to supply technically connected solutions without unnecessary delays.

Precise deployment in heavy industrial units

The H17R 400-D-6-6 model is suitable for a process-water pumping station, a blower in the energy sector, a crusher drive in a stone-processing operation, a compressor unit in a chemical plant, an agitator in a paper-production process, a cooling-tower fan, a belt conveyor in a mine, a rolling stand in metallurgy, a rotary dryer in mineral processing, an extruder in material production, a raw-material mill, a discharge pump in a sugar refinery and a homogenization line in the food industry. In each of these applications, the combination of power reserve, high efficiency and a robust arrangement of 6326-C3 bearings on both the DE and NDE sides is utilized.

Design prepared for long service intervals

A weight of 4290 kg and rotor moment of inertia of 14,2 kg·m² support stability during operation in technological assemblies where damping of short-term load fluctuations is required. Insulation class F and temperature rise B give the motor room for reliable operation even in adverse ambient conditions. For manufacturers of large machines, it is important that such an assembly reduces pressure on planning service shutdowns and simplifies drive standardization within a single project.

VYBO Electric offers a solution based on experience with large industrial drives and practical supply to technologically demanding operations. If you need a motor for a 6 000 V mains voltage with an emphasis on service life, efficiency and a stable load profile, take advantage of the offer and choose an electric motor prepared for long-term operation in a demanding environment.

900 rpm electric motor for production focused on efficiency

In real operations, a 900 rpm electric motor is suitable wherever smooth power transmission to a process machine is needed without unnecessary losses in energy conversion. This approach is particularly advantageous for pumps with higher delivery resistance, large fans, mixing systems and conveyors that operate continuously. Combined with the VYBO Electric design, this is a solution that supports a long operating cycle and reasonable energy and service costs.
