Choosing the right 2800 kW drive for the duty

When selecting a 2800 kW medium and high voltage electric motor, the first decisions usually concern network voltage, required speed and the duty profile of the driven equipment. The H27R-HD-Modular series is designed for this type of project-specific selection, with variants for 6000 V and 10 000 V, plus 3300 V and 11 000 V available on request.

For mining conveyors and mine ventilation, the choice often depends on whether the driven machine needs a higher nominal speed or a slower speed group. The fixed nominal speeds depend on pole count: 2POL approx. 2900-3000 rpm, 4POL approx. 1400-1500 rpm, 6POL approx. 900-1000 rpm, 8POL approx. 700-750 rpm, 10POL approx. 550-600 rpm and 12POL approx. 450-500 rpm. These are fixed nominal speed groups, not a continuously adjustable range.

Typical application areas

The H27R 2800 kW electric motor can be specified for conveyor drives, mine ventilation fans, process pumps, compressors, mills and other heavy industrial machinery. As a three-phase electric motor built for S1 continuous operation, it suits installations where steady output and controlled configuration are more important than a standard catalogue fit.

Technical features that support selection

Key construction details include an IP55 enclosure, IC611 air-to-air cooling, a welded steel frame, insulation class F with temperature rise class B, and anti-friction bearings with grease or oil lubrication depending on the final specification. Monitoring and protection can include PT100 sensors for stator and bearings, 3 PTC thermistors and a 230 V space heater. The motor is also suitable for use with a frequency converter when configured correctly for the application.
