Voltage and speed selection for steel plant drives

Choose the right 1000 kW medium and high voltage electric motor by matching supply voltage, pole count and nominal speed to the duty required in steel and metallurgy process drives. The H27R-HD-Modular series covers 6000 V and 10 000 V versions at this power rating, with 3300 V and 11 000 V available on request. Fixed nominal speed groups are offered by 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.

Technical features that support demanding operation

This H27R 1000 kW electric motor is a three-phase electric motor with a welded steel frame, IP55 protection, IC611 air-to-air cooling and insulation class F with temperature rise class B. It is intended for S1 continuous operation and can be configured for use with a frequency converter when the application requires it. Monitoring and protection options include PT100 sensors for stator and bearings, 3 PTC thermistors and a 230 V space heater. Anti-friction bearings are grease or oil lubricated depending on the final configuration.

Application suitability and modular options

Typical uses include pumps, fans, compressors, conveyors, mills, ventilation systems and other heavy industrial machinery. The modular design of the series supports adaptation of voltage, cooling, mounting, accessories and monitoring for project-specific requirements.
