Product Description:

The 2AD134B-B05OB1-ES37-A2N1 Servo Motor of Bosch Rexroth features a digital servo feedback system that includes an integrated multiturn absolute encoder for accurate positioning and motion control. Its mechanical power is rated at 11.9 kW and is equipped with standard bearings to ensure reliable rotational support under load. It falls under the 2AD 3-Phase Induction Motors series and has a rated speed of 1500 revolutions per minute.

The 2AD134B-B05OB1-ES37-A2N1 servo motor servo motor includes a holding brake that delivers 100 Nm braking torque that can be electrically released and designed for heavy load work. The vibration severity is categorized under Grade R that complies with standard mechanical stability requirements. In this servo module cooling is provided through an axial blower that directs airflow inwards to maintain thermal conditions for continuous duty cycles. The module mounting style is flange mounting that supports rigid and secure installation and also simplifies mechanical assembly. The motor protection class is IP65 that protects against dust ingress and low pressure water and its blower has a separate protection class of IP24 that allows ventilation with limited exposure. It comes with a plain type shaft without a shaft sealing ring and the rated current required for operation is 28 A that ensures proper electrical supply. It can effectively transmit power with its rated power capability of 76 nm

The 2AD134B-B05OB1-ES37-A2N1 servo motor has a moment of inertia of 0.054 kgm² that supports dynamic control and its maximum speed capacity is 7500 rpm. Its encoder feedback supports accurate positioning and monitoring and its heavy duty holding brake enhances operational safety during standstill conditions. It supports a wide range of applications that demand stable performance and long term reliability.
