Product description

The Siemens 1PH81841HD002DA2 is a SIMOTICS M compact asynchronous motor featuring a high-resolution HTL incremental encoder (1024 S/R) and a Pt1000 temperature sensor. It offers 39 kW of power at 1000 RPM with 372 Nm of torque (87 A, 340 V), and also provides 44 kW at 1150 RPM (365 Nm, 86 A, 390 V) and 50 kW at 1350 RPM (354 Nm, 84 A, 450 V). This motor is designed with forced ventilation (DE to NDE airflow) and has an IP55 protection rating. It is built in IM B3 design with a shaft that has a fitted key and half-key balancing.

This motor is ideal for applications requiring precise speed and position control, such as advanced machine tools, robotics, and automated assembly lines. The integrated encoder and temperature sensor enhance its suitability for closed-loop control systems.
