Siemens 1PH8186-1AD00-2BA2 SIMOTICS M-1PH8 Compact 67 kW 1350 r/min IP55 Asynchronous Motor

The Siemens 1PH8186-1AD00-2BA2 is a SIMOTICS M-1PH8 compact asynchronous motor rated across 3 speed points from 1000 to 1350 r/min, delivering up to 67 kW, 474 Nm and 112 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 422 kg.

Technical Specifications

Selection Notes

The 1PH8186 frame carries a 6,520 kgcm² rotor against the 1PH8184's 4,890 kgcm², and it shows in the torque figures: this IP55 winding holds a near-constant 112 A while torque only drifts from 487 Nm at 1000 r/min to 474 Nm at 1350 r/min, a flatter curve than the smaller frame's equivalent winding. Choose this frame over the 1PH8184 base-speed IP55 winding when the driven load needs more than 354 Nm through the 1000-1350 r/min band. Choose the IP23 open-circuit winding in this same frame instead when the extra 26 kW it delivers at the same speed band is worth accepting open ingress protection. The 422 kg net weight and larger rotor inertia both raise the mechanical and acceleration-torque budget the mounting structure and drive need to account for.
