Applications for energy and power generation drives

For turbine auxiliaries, boiler feed systems, cooling water duties, forced-draught ventilation and other plant services, a 3300 kW medium and high voltage electric motor needs to be selected around the actual duty rather than just the nameplate output. The H27R-HD-Modular series gives you that flexibility, with variants suited to pumps, fans, compressors, conveyors, mills and other heavy industrial machinery within energy and power generation environments.

Choosing voltage, pole count and speed

This power rating is available for 6000 V and 10 000 V networks, with 3300 V and 11 000 V offered on request. You can also match the drive to the required nominal speed by selecting the pole version: 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 speeds linked to the selected pole version, which makes specification clearer for procurement and engineering teams.

Technical features for project specification

The H27R 3300 kW electric motor is a three-phase electric motor with a welded steel frame, IP55 enclosure, IC611 air-to-air cooling, insulation class F, temperature rise class B and S1 continuous duty. Standard monitoring includes PT100 sensors for stator and bearings, 3 PTC thermistors and a 230 V space heater. Depending on the final configuration, anti-friction bearings may be grease or oil lubricated. The unit can also be configured for frequency converter use when the application calls for it.

If you are comparing drive options for a new build or a plant upgrade, VYBO Electric can adapt voltage, cooling, mounting form and accessories to suit the project.
