Siemens 1PH8133-1AF00-2BA2 SIMOTICS M-1PH8 Asynchronous Motor 22 kW 2200 rpm IP55

The Siemens 1PH8133-1AF00-2BA2 is a SIMOTICS M-1PH8 compact asynchronous motor for variable-speed operation, delivering four rated points from 15 kW at 1500 rpm up to 22 kW at 2200 rpm (96 Nm across the range, up to 34 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 1PH8133-1AF00-2BA2 is rated across four points spanning 15 kW at 1500 rpm to 22 kW at 2200 rpm, placing it in the field-weakening band (1500 to 2200 rpm), covering higher shaft speeds at reduced torque as voltage rises toward the top point. 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 106 kg frame, the -1AD00 variant in the same frame stays in the constant-torque range below 1500 rpm where more torque is available at lower speed. The Pt1000 sensor allows winding temperature monitoring on the drive side without adding a separate encoder feedback loop.
