Product Description:

The 2AD280A-B03LL1-AS07-A2N1 is an AC induction motor produced by Bosch Rexroth Indramat as part of the 2AD 3-Phase Induction Motors series. In automated machine tools, material-handling lines, and other continuous-duty stations, this motor supplies constant torque while accepting digital position feedback from the drive controller to maintain closed-loop speed regulation. This frame is commonly used in larger conveyor sections, spindle auxiliaries, and process equipment that require steady operation across long production cycles.

Cooling air is moved through the housing by an axial blower, so stator heat is removed independently of machine airflow. Motion data are returned through digital feedback with a multi-turn absolute encoder, allowing the drive to track position after power loss. Installation is simplified by foot mounting, and the supply conductors reach the stator through a junction box that is factory oriented to the left side when the user faces the shaft. Because the connection hardware is on that flank, cables exit cleanly to the plant's cable trays without crossing the motor body. This model ships without a holding brake, so any static load must be restrained by the drive or external clamping. Mechanical output passes through a smooth shaft without a seal, minimizing friction where liquid contaminants are not expected. A separate statement notes that the opposite side B shaft end is absent, reducing overall length and eliminating an unused coupling surface. Standard bearings are fitted to handle radial forces generated by belts or direct-coupled pulleys.

The motor has frame size 280, so mounting hole pitch and foot height align with other IEC motors in that envelope. Length code A keeps the package compact. Dynamic tolerances correspond to vibration grade R, supporting operation on precision equipment without additional balancing. Electrical properties correspond to winding code AS, allowing the paired inverter to apply the correct voltage-to-frequency profile.
