Product Description:

The 2AD280B-B03LL1-AS06-B2N1 is an AC induction motor engineered by Bosch Rexroth Indramat for the 2AD 3-phase induction motors series. In automated lines, it converts three-phase electrical power into controlled mechanical rotation that can be regulated by matching drives and controllers. Its output supports conveyors, metal-cutting spindles, and packaging axes, while matching drives can monitor operating feedback in real time to regulate flux and speed for repeatable motion during continuous industrial operation. This makes the motor suitable for applications that need steady speed, coordinated acceleration, and stable torque under varying process loads.

The unit is supplied without a holding brake, so load restraint must be provided externally when the system is de-energized. Cooling is handled by an integrated axial blower that forces air through longitudinal ducts to remove stator heat during continuous duty. Rotor position and speed are reported through digital servo feedback, which supports vector control and stable regulation across changing loads. With a motor size of 280, the motor uses a large frame for high torque capacity, and foot mounting supports installation on machine beds with standard base fastening. Standard bearings carry radial loads, the drive-side shaft is balanced with a full key, and side B is delivered without a shaft end to reduce overall length.

The motor has a length code of B, which gives a mid-range active iron depth and a balanced overall envelope for machines that need substantial output without the longest housing. Power enters through a sealed junction box, and the motor uses a left-side power connection to simplify cable routing along the frame or guard structure. It is built to vibration grade R, which helps limit transmitted oscillation during higher-speed operation. The AS winding is matched to standard 400 V class inverters, and the design omits a shaft seal to reduce friction at the drive end.
