Siemens 1PH8103-1AF00-2BA2 SIMOTICS M-1PH8 Compact Asynchronous Motor 5.5kW 1500rpm IP55

The Siemens 1PH8103-1AF00-2BA2 is a SIMOTICS M-1PH8 compact asynchronous motor rated 5.5 kW at 1,500 rpm with 35 Nm and 13.5 A at 368 V. Output climbs to 7.7 kW at 2,200 rpm across its four duty points as voltage rises to 480 V and current eases to 12.7 A. Forced ventilation and IP55 protection carry a Pt1000 winding temperature sensor.

Technical Specifications

Selection Notes

This winding is rated for a higher current class, delivering 5.5-7.7 kW against 33-35 Nm torque from a 368-480 V supply. Current eases from 13.5 A to 12.7 A as speed rises from 1,500 to 2,200 rpm, while torque holds in the 33-35 Nm band across the same range. IP55 sealing, forced ventilation, and fixed-bearing construction at vibration severity grade R/A suit continuous, enclosed machine-tool duty rather than exposed or intermittent installations.

Applications

Forced ventilation and IP55 sealing suit enclosed machine-tool bases rather than open, exposed mounts. The 5.5-7.7 kW output band across 1,500-2,200 rpm fits mid-range spindle or main-drive axes needing more continuous power than lighter windings in this frame size.
