Siemens 1PH8163-1AD00-2BA2 SIMOTICS M-1PH8 Asynchronous Motor 31 kW 1500 rpm IP55

The Siemens 1PH8163-1AD00-2BA2 is a SIMOTICS M-1PH8 compact asynchronous motor for variable-speed operation, delivering four rated points from 22 kW at 1000 rpm up to 31 kW at 1500 rpm (197 to 210 Nm, up to 55 A). It runs on forced ventilation independent of shaft speed, carries IP55 protection, and includes a Pt1000 temperature sensor but no encoder.

Technical Specifications

Selection Notes

The 1PH8163-1AD00-2BA2 is rated across four points spanning 22 kW at 1000 rpm to 31 kW at 1500 rpm, placing it in the low-speed constant-torque band (1000 to 1500 rpm). IM B3 foot mounting with forced ventilation keeps the cooling fan running independently of shaft speed, so torque output does not fall off at the low end of the range. For the same 196 kg frame, the -1AF00 variant in the same frame delivers higher speed and power for pump or fan duty above base speed. The Pt1000 sensor allows winding temperature monitoring on the drive side without adding a separate encoder feedback loop.
