About the 1PH8288-1AD10-2BU2
About the 1PH8288-1AD10-2BU2
The Siemens 1PH8288-1AD10-2BU2 is a SIMOTICS M-1PH8 compact asynchronous motor covering 1000-1350 rpm at up to 305 kW, with forced ventilation (NDE to DE) and an IP55 degree of protection. Shaft height is 280 mm, and the winding supports ratings from 226 kW at 335 V up to 305 kW at 450 V. It ships in Anthracite RAL 7016 with a Pt1000 temperature sensor and no encoder.
Selection Notes
This 1000-1350 rpm winding, run on the forced-ventilation (NDE to DE) frame, holds IP55 for installations exposed to washdown or dust where an open IP23 enclosure would not be suitable. Selecting the BLM/SLM connection yields 226 kW at 1000 rpm rising to 305 kW at 1350 rpm; the ALM connection instead delivers 260 kW at 1150 rpm with a 385 V supply. With a 280 mm shaft height and 63,000 kgcm2 rotor inertia, the 53-minute thermal time constant gives more margin for load fluctuations than the open-ventilated variant of this frame.
