Electric motor 1250 kW, 746 rpm, 6000 V, H17R 560-A-8-6 MV

In heavy-duty operation, a power supply without fluctuation is crucial, especially where the technology operates under long-term load. The H17R 560-A-8-6 with an output of 1250 kW is designed for operation in the 700-750 rpm range, making it suitable for applications requiring stable torque, precise operating characteristics and reliable performance under high energy demand. In this speed range, the medium-voltage drive offers a clear reserve for production continuity.

Stable operation at a speed class of 700-750 rpm

The motor design uses a 560 mm frame size and the corresponding frame dimension according to IEC, which makes integration into existing assemblies and OEM manufacturers’ projects easier. The rated current of 151 A, efficiency of 96.3 % and power factor of 0.83 support the efficient use of electrical energy under long-term load. The rotor inertia of 120.0 kg·m² also helps with smooth starting and drive stability under a variable operating profile.

• copper bars in the rotor cage supports robust behaviour under load and contributes to reliable torque transmission.
• The rated torque of 16002 Nm provides a sufficient basis for demanding starts and steady heavy-duty operation.
• The values Tst/Tn 0.9 %, Tmax/Tn 2 % and Ist/In 5.1 % help in drive design with regard to grid and process conditions.
• Insulation class F together with temperature rise B increases the operating reserve in environments with longer load periods.

Use in drives for heavy industrial operation

This three-phase 6 kV motor is suitable for drives for heavy industry, where convincing performance at stable speeds and high operating discipline are required. It is used in pumps, compressors, fans, mills, crushers, conveyors, mixers, rolling lines, extruders, vacuum pumps, drums, winders, rotary kilns, process units and power assemblies operating on medium-voltage infrastructure. For drive system integrators, the weight of 8400 kg is also important, reflecting robust construction for long-term service.

Monitoring bearings and winding under continuous load

The equipment includes PT100 sensors for the winding and bearings, an anti-condensation heater and a set of three PTC thermistors, supporting safer operational monitoring and timely response from the control system. The DE bearing and the NDE bearing are available on request, so the solution can be adapted to the project’s specific technical specification. For applications requiring a 6000 V electric motor with high reliability and continuous output, this is a suitable basis for long-term operation with a lower risk of unplanned downtime.
