About the 1PH8288-1AF40-2BU2
The Siemens 1PH8288-1AF40-2BU2 is a SIMOTICS M-1PH8 compact asynchronous motor covering 1500-2000 rpm at up to 630 kW, with open-circuit ventilation and an IP23 degree of protection. Shaft height is 280 mm, and the winding supports ratings from 480 kW at 345 V up to 630 kW at 455 V. It ships in Anthracite RAL 7016 with a Pt1000 temperature sensor and no encoder.
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.
