Siemens 1PH8165-1AD00-2BA2 SIMOTICS M-1PH8 Compact 37.7 kW 1500 r/min IP55 Asynchronous Motor

The Siemens 1PH8165-1AD00-2BA2 is a SIMOTICS M-1PH8 compact asynchronous motor rated across 4 speed points from 1000 to 1500 r/min, delivering up to 37.7 kW, 240 Nm and 65 A at 430 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 230 kg.

Selection Notes

The 1AD00 winding is the low-speed end of the 1PH8165 frame, spanning 1000-1500 r/min and topping out at 37.7 kW / 240 Nm at 430 V. Pick this winding over a higher-speed winding in the same frame when the driven load's top speed sits near 1500 r/min and torque through the lower part of the range matters more than peak output at the high end — the 267 Nm available at 1000 r/min is the highest torque figure in this motor's whole speed table. Forced ventilation (DE to NDE) keeps the winding within its IP55 rating independent of shaft speed, and the Pt1000 sensor gives the drive direct stator winding temperature feedback without a separate encoder channel. The IM B3 foot mounting is also cataloged for IM V5 and IM V6 shaft-up/shaft-down installation, so the same winding fits a horizontal foot-mounted machine bed or a vertical spindle arrangement without a different order number. Standard fixed bearings at vibration severity grade R/A and shaft/flange accuracy grade R are the baseline mechanical tolerance for this frame; specify a closer grade only if the downstream coupling requires it.
