Applications in energy and power generation

The 4500 kW medium and high voltage electric motor in the H27R-HD-Modular series is suited to heavy-duty drive systems in energy and power generation environments. Typical uses include boiler feed pumps, circulation pumps, induced draught fans, compressors and other auxiliary drives where stable operation and defined motor parameters are important.

Technical overview and variant selection

This H27R 4500 kW electric motor is available as a medium and high voltage asynchronous motor in 6000 V and 10 000 V versions, with 3300 V and 11 000 V available on request. Pole selection defines the fixed nominal speed group: 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. The design includes an IP55 enclosure, IC611 air-to-air cooling, welded steel frame, insulation class F, temperature rise class B and S1 continuous duty. PT100 sensors, 3 PTC thermistors and a 230 V space heater support monitoring and protection. The motor can also be configured for use with a frequency converter when the application requires it.

For project specification

These motors are used in mills, conveyors, ventilation systems and other industrial processes where a robust three-phase electric motor is needed.
