Siemens 1PH8184-1AD30-2BA2 SIMOTICS M-1PH8 Compact 74 kW 1350 r/min IP23 Asynchronous Motor

The Siemens 1PH8184-1AD30-2BA2 is a SIMOTICS M-1PH8 compact asynchronous motor rated across 3 speed points from 1000 to 1350 r/min, delivering up to 74 kW, 523 Nm and 118 A at 450 V. It runs IP23-protected with open-circuit ventilation (DE to NDE), carries a Pt1000 temperature sensor and no encoder, and mounts IM B3 at a net weight of 350 kg.

Selection Notes

This open-circuit-ventilated winding covers the same 1000-1350 r/min base speed band as the sealed IP55 winding in this frame but reaches 74 kW / 523 Nm — 24 kW and 169 Nm more — because drawing cooling air straight through the frame instead of over a sealed housing removes the IP55 thermal ceiling. Choose it when the installation is a clean, controlled panel room where IP23 ingress protection is acceptable and the extra output is worth the exposed air path; choose the IP55 winding instead for a dusty or washdown-exposed location. The longer 26-minute thermal time constant against the IP55 winding's 22 minutes reflects the larger thermal margin the open air path gives this frame before it needs to derate.
