Series benefits and application focus

The 1750 kW medium and high voltage electric motor from the H27R-HD-Modular series offers a practical balance of modular configuration, robust construction and wide application scope. It is intended for heavy-duty industrial drives where the exact electrical and mechanical parameters need to be matched to the installation rather than taken as a fixed standard.

Typical uses include oil and gas compressors, process pumps, booster pumps and large ventilation systems. The same motor platform can also be specified for other industrial duties such as fans, conveyors or mill drives, where a three-phase electric motor with defined operating parameters is required.

Voltage, pole count and speed groups

This power rating is available for 6000 V and 10 000 V networks, with 3300 V and 11 000 V available on request. Users can select from 2POL, 4POL, 6POL, 8POL, 10POL and 12POL versions, with the following fixed nominal speed groups: 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.

Configuration options and technical details

The H27R motor is a medium and high voltage asynchronous electric motor with IP55 protection, IC611 air-to-air cooling, insulation class F, temperature rise class B and S1 continuous duty. A welded steel frame supports the mechanical design, while anti-friction bearings may be grease or oil lubricated 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 unit can be configured for frequency converter use when appropriate for the application. Mounting forms such as B3, B35, V1 and V15 are available, and cooling can be adapted with IC616 or IC666 on request.
