Siemens 1PH8186-1AD30-2BA2 SIMOTICS M-1PH8 Compact 98 kW 1350 r/min IP23 Asynchronous Motor

The Siemens 1PH8186-1AD30-2BA2 is a SIMOTICS M-1PH8 compact asynchronous motor rated across 3 speed points from 1000 to 1350 r/min, delivering up to 98 kW, 693 Nm and 152 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 422 kg.

Selection Notes

At 707 Nm and 74 kW down at 1000 r/min, this is the highest low-speed torque figure in this ten-part 1PH8 line-up, and it holds above 690 Nm across the whole 1000-1350 r/min band. Choose this open-circuit-ventilated 1PH8186 winding over the sealed IP55 winding in the same frame when the load needs more than the IP55 winding's 474 Nm ceiling and the site allows open ingress protection. Choose it over the smaller 1PH8184 frame's equivalent open-ventilated winding when 523 Nm is not enough torque for the application. The 152 A rated current at 1350 r/min and the 6,520 kgcm² rotor inertia both size the drive's output stage and the acceleration torque budget for this variant.
