Selection Notes
This 1500-2000 rpm winding uses open-circuit ventilation to reach up to 630 kW, trading the washdown-rated IP55 enclosure of the forced-ventilation variant for higher continuous output. Selecting the BLM/SLM connection yields 480 kW at 1500 rpm rising to 630 kW at 2000 rpm; the ALM connection instead delivers 560 kW at 1750 rpm and 910 A. The 22-minute thermal time constant means duty-cycle sizing should account for a faster thermal rise than the forced-ventilation frame at this power level.
