Siemens 1PH8184-1AF30-2BA2 SIMOTICS M-1PH8 Compact 98 kW 2000 r/min IP23 Asynchronous Motor

The Siemens 1PH8184-1AF30-2BA2 is a SIMOTICS M-1PH8 compact asynchronous motor rated across 3 speed points from 1500 to 2000 r/min, delivering up to 98 kW, 468 Nm and 156 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 is the highest-output 1PH8184-frame variant in the 1500-2000 r/min speed band, reaching 98 kW at both 480 V-network extended points and at the standard 450 V 2000 r/min point — the power ceiling is set by current (156 A) rather than by voltage headroom at the top of the range. Choose it over the sealed IP55 winding covering the same speed band when the installation can accept IP23 open ingress protection and the application needs the full 98 kW; the IP55 winding caps out 30 kW lower at 68 kW. Against the 1000-1350 r/min winding in this frame, this winding gives up low-end torque (468 Nm vs 523 Nm) for a higher continuous speed range.
