Group 1: Large machines with rated power above 300 kW;
electrical machines with shaft height H >= 315 mm.
These machines normally have sleeve bearings. The range of operating or nominal speeds is
relatively broad and ranges from 120 r/min to 15 000 r/min.
Group 2: Medium-sized machines with a rated power above 15 kW up to and including 300 kW;
electrical machines with shaft height 160 mm <= H < 315 mm.
These machines normally have rolling element bearings and operating speeds above 600 r/min.
