Product Description:

The 2AD160B-B35RB2-BS03-B2N2/S025 is an induction motor optimized for industrial automation systems. This Bosch Rexroth motor is used in machine tools and production systems, where consistent torque and accurate positioning are required. It is part of the 2AD series of AC motors and corresponds to frame size 160. This model is manufactured with housing length B to indicate a medium construction length.

The 2AD160B-B35RB2-BS03-B2N2/S025 induction motor configuration follows the B35 mounting standard. With support for both flange and foot installation, it adapts easily to a wide range of machine setups. The power connection terminal of the motor is positioned on the right-hand side. Its outlet direction faces side B. The cooling of the motor is provided by an axial fan, which drives airflow from side A to side B. The winding code BS identifies the stator coil design. This 2AD160B-B35RB2-BS03-B2N2/S025 induction motor is supplied without an integrated holding brake. The position detection is enabled by a type 3 high-resolution encoder for precise motion feedback. The output shaft has a keyed design and is dynamically balanced to ensure effective torque transfer. The motor is equipped with standard bearings. Its vibration classification is indicated with code S. These design specifications support continuous-duty operation.

The 2AD160B-B35RB2-BS03-B2N2/S025 induction motor provides a nominal output of 30 kW with a rated torque of 191 Nm. The base speed of the motor is about 1500 RPM. The rated current of the motor is 72 A (rms value). The rotor moment of inertia is 0.174 kg·m², and the thermal response duration of the winding system is 60 minutes. This ensures predictable heat behavior under cyclic duty. The motor is designed to reach speeds up to 6000 RPM. The nominal supply voltage is 305 V (rms value).
