Product Description:

The 2AD280B-B03LL1-AS07-B2N1 is an AC induction motor produced by Bosch Rexroth Indramat for the 2AD 3-Phase Induction Motors series. It acts as a prime mover in industrial automation, converting three-phase electrical input into controlled mechanical torque for conveyors, machine tools, and packaging axes. Integrated position feedback enables closed-loop regulation by compatible drive controllers, giving consistent speed across the required operating band. Because the feedback is integrated into the motor package, the drive can monitor rotor movement without requiring a separate external sensing assembly.

The motor is supplied without a holding brake, so load retention must be handled by the machine mechanics or the connected drive. Cooling air is forced through the stator by an axial blower, maintaining temperature without external water or oil circuits. Position and speed are transmitted to the inverter by digital feedback with a multi-turn absolute encoder, enabling homing-free restart after power loss. The frame corresponds to size 280, and the B-length housing provides high continuous torque within the available footprint. Installation uses foot mounting, and the power leads exit to the left, which supports cable routing on left-oriented machine layouts. Standard bearings support the balanced rotor, and the shaft is machined with a full key for direct coupling to driven equipment. The keyed output supports positive torque transfer to pulleys, gearboxes, or couplings used on production machinery.

The shielded mains conductors terminate inside a junction box, simplifying service loops and keeping high-voltage paths separate from control wiring. Dynamic behavior meets vibration grade R, which helps limit displacement during rapid load changes. Electromagnetic performance is set by the winding code AS, allowing the inverter to apply the correct current limits for this motor. The drive-end shaft is balanced with the full key, while the opposite side has no shaft end. The assembly is without a shaft seal, so external sealing must be provided at the machine interface. Separating the power terminations from signal paths also helps keep the wiring layout orderly inside the machine cabinet or motor connection area.
