Product Description:

The 2AD280A-B03RL1-AS06-A2N1 is an AC induction motor built by Bosch Rexroth Indramat for the 2AD 3-Phase Induction Motors series. As a squirrel-cage drive element, it supplies constant torque and speed for conveyors, extruders, and other industrial axes that require reliable three-phase power conversion in automated machinery. The motor uses length code A, which is the shortest rotor stack available in the 280 frame and helps reduce mass where space or inertia limits apply.

This model relies on an axial blower that pushes cooling air along the stator housing so continuous thermal loading can be maintained without derating. A frame size of 280 gives the motor a large stator diameter that pairs with high-current inverters for elevated shaft power. The motor is delivered without a holding brake, so external clamping or drive torque must retain loads during power loss. A high-resolution digital servo feedback encoder is integrated for precise speed regulation and position detection. Installation uses foot mounting on the base, while the three-phase supply enters through a right-side junction box whose terminals face left when viewed from the shaft end.

The mechanical interface uses a smooth shaft without a shaft seal, minimizing runout when coupled to gearboxes but requiring external protection against fluid ingress. Dynamic balance is graded at R, which limits vibration transmitted to the mounting structure during full-speed operation. The motor uses winding code AS, matching the impedance and thermal constants expected by compatible Indramat drive controllers. Standard bearings support the rotor, and side B is supplied without a shaft end to keep the overall footprint compact. Power connections remain on the right side of the fan housing, which helps keep cable routing clear in standard control enclosures.
