Product Description:

The 2AD280B-B03RL1-AS06-B2V1 is an AC induction motor manufactured by Bosch Rexroth Indramat and part of the 2AD 3-Phase Induction Motors series. The unit converts three-phase electrical power into continuous rotary motion for production equipment that requires closed-loop speed regulation and high uptime, such as machining centers and transfer lines. Its design is suited to applications that run for long periods and must maintain stable speed when process loads change. Because it is an induction motor, it is typically paired with a matching inverter that manages acceleration, speed holding, and load response during operation.

This motor is cooled by an axial blower that directs airflow along the stator housing to remove heat during heavy load cycles. Rotor position is returned to the drive by digital servo feedback, enabling tight velocity and torque control, and heavy-duty bearings support the radial and axial forces associated with this frame size. Installation uses foot mounting, so the base casting sits directly on machine beds without an added flange, and the motor is supplied without a holding brake for systems that hold position through drive torque or external locking devices. Power enters from the left side of the housing, and the conductors terminate on the right when viewed toward the shaft, which can simplify cable routing inside standard cabinets.

The motor has a frame size of 280, which sets the shaft height and bolt circle, while motor length code B sets the overall stack length for the intended continuous output. Line conductors land inside a junction box that helps protect the terminations from coolant spray, and dynamic balance conforms to vibration grade R. The shaft is supplied without a shaft seal and is balanced with the full key installed, while the secondary end of the rotor is closed because it is built without a second shaft end. This arrangement helps keep the rear of the motor compact where space behind the machine is limited. Electrical characteristics follow the AS winding code, matching the resistance and inductance values used by compatible Rexroth inverters.
