- Description
The Siemens 1PH8288-1AF10-2BU2 is a SIMOTICS M-1PH8 compact asynchronous motor covering 1500-2000 rpm at up to 385 kW, with forced ventilation (NDE to DE) and an IP55 degree of protection. Shaft height is 280 mm, and the winding supports ratings from 320 kW at 345 V up to 385 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, run on the forced-ventilation (NDE to DE) frame, holds IP55 for washdown-adjacent or dusty installations. Selecting the BLM/SLM connection yields 320 kW at 1500 rpm rising to 385 kW at 2000 rpm; the ALM connection instead delivers 340 kW at 1750 rpm with 580 A. Sharing the 280 mm shaft height and 63,000 kgcm2 rotor inertia of the lower base-speed variant of this frame, it suits applications needing higher rpm without a frame-size change.
