Siemens 1PH8228-1AF00-2BA2 SIMOTICS M-1PH8 Compact Asynchronous Motor 160kW 1500 r/min IP55

The Siemens 1PH8228-1AF00-2BA2 is a SIMOTICS M-1PH8 compact asynchronous motor rated 160 kW and 1019 Nm at 1500 r/min, extending to 196 kW at 2000 r/min in the field-weakening range. Built to IP55 with forced ventilation (DE to NDE), it has a 225 mm shaft height, carries a Pt1000 temperature sensor with no encoder, and weighs 870 kg.

Selection Notes

The IP55 enclosure and forced ventilation on the 1PH8228-1AF00-2BA2 suit installations with dust, moisture, or washdown exposure that an open-circuit-cooled winding in the same 225 mm frame cannot tolerate. Continuous output is 160 kW at 1500 r/min, rising to 196 kW once the field-weakening range is reached on a 480 V supply. Its 55-minute thermal time constant gives more margin against transient overload than the shorter time constant typical of an open-circuit-ventilated sibling in the same frame. Pick the open-circuit-ventilated version instead when the installation environment is clean and a higher continuous power rating in the same frame matters more than enclosure protection.
