Siemens 1PH8105-1AF00-2BA2 SIMOTICS M-1PH8 Compact Asynchronous Motor 7kW 1500rpm IP55

The Siemens 1PH8105-1AF00-2BA2 is a SIMOTICS M-1PH8 compact asynchronous motor rated 7 kW at 1,500 rpm with 45 Nm and 17.5 A at 348 V. Output climbs to 9.9 kW at 2,200 rpm across its four duty points as voltage rises to 485 V and current eases to 17 A. Forced ventilation and IP55 protection carry a Pt1000 winding temperature sensor.

Technical Specifications

Selection Notes

At 65.0 kg with 45 Nm starting torque, this is the largest and highest-torque frame in this specification. Current holds close to 17-17.5 A across the full 1,500-2,200 rpm range while torque steps down from 45 Nm to 43 Nm as speed rises, so the drive's current rating is set almost entirely by the base-speed point. The Pt1000 sensor lets the drive trip on actual winding temperature instead of a thermal model. IP55 sealing, forced ventilation, and fixed-bearing construction at vibration severity grade R/A suit continuous, enclosed machine-tool duty.

Applications

Forced ventilation and IP55 sealing suit enclosed machine-tool bases rather than open, exposed mounts. The 43-45 Nm torque band and 7-9.9 kW output suit heavier spindle or main-drive axes that need more continuous torque than lighter-frame 1PH8 motors.
