Series benefits for large industrial duties

The H27R-HD-Modular series gives you a flexible way to specify a 1250 kW medium and high voltage electric motor for large-scale industrial fans, ventilation systems and other heavy-duty drive systems. Its modular concept supports a wide choice of voltages, pole counts and configuration options, helping buyers match the motor more closely to the application rather than adapting the application to the machine.

For this power rating, the main network options are 6000 V and 10 000 V. Versions on request can also be prepared for 3300 V or 11 000 V. The motor family covers 2POL, 4POL, 6POL, 8POL, 10POL and 12POL, with fixed nominal speed groups depending on the selected pole version: around 2900-3000 rpm, 1400-1500 rpm, 900-1000 rpm, 700-750 rpm, 550-600 rpm and 450-500 rpm.

Technical features that support industrial operation

Built as a three-phase electric motor with a welded steel frame, the H27R unit is specified for robust service in severe industrial environments. Standard features include IP55 enclosure protection, IC611 air-to-air cooling, insulation class F, temperature rise class B and S1 continuous duty. Depending on the final configuration, bearings may be grease or oil lubricated, and monitoring can include PT100 sensors for stator and bearings, 3 PTC thermistors and a 230 V space heater.

• Frequency: 50 Hz as standard, 60 Hz available on request
• Efficiency: up to 97.4 %, depending on configuration
• Mounting forms: B3, B35, V1 and V15
• Converter use: suitable for frequency converter operation when configured for the application

This H27R 1250 kW electric motor range suits fans, induced draught systems, compressors, pumps, conveyors and mills where a technically defined industrial drive is required.
