Siemens 1PH8184-1AD00-2BA2 SIMOTICS M-1PH8 Compact 50 kW 1350 r/min IP55 Asynchronous Motor

The Siemens 1PH8184-1AD00-2BA2 is a SIMOTICS M-1PH8 compact asynchronous motor rated across 3 speed points from 1000 to 1350 r/min, delivering up to 50 kW, 354 Nm and 84 A at 450 V. It runs IP55-protected with forced 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 is the enclosed, IP55 forced-ventilation winding of the 1PH8184 frame's base 1000-1350 r/min speed band, capped at 50 kW / 354 Nm because the sealed housing limits how much heat the frame can shed. Choose it over the IP23 open-circuit winding covering the same speed band when the installation is exposed to dust, coolant mist or washdown and the extra 24 kW available from open ventilation is not needed. Against the higher-speed 1500-2000 r/min winding in this frame, this winding trades top speed for torque — 372 Nm at 1000 r/min is the highest torque figure this frame produces at IP55. The 4,890 kgcm² rotor inertia and 22-minute thermal time constant set how quickly the drive can cycle it under repeated starts before thermal limits intervene.
