Product Description:

The 2AD280B-B03LL1-AS07-D2V1 is an AC induction motor produced by Bosch Rexroth Indramat within the 2AD 3-Phase Induction Motors series. This model drives conveyors, presses, and other continuous-duty loads in automated lines by converting three-phase electrical power into mechanical rotation. It is intended for industrial motion systems that require steady torque and repeatable speed control over long operating periods. Its housing follows the footprint used in this motor line, so it can be paired with Rexroth drive controllers and mounted directly on machine frames without additional adapter plates.

The mechanical package features heavy-duty bearings that support radial and axial forces during long production cycles. A frame size of 280 provides a broad stator diameter for higher magnetic flux while keeping the overall length in the mid-range B category. Installation uses foot mounting, allowing the housing to bolt to a baseplate or skid without end-flange brackets. Thermal management is provided by an axial blower attached to the non-drive side, and the fan pushes air along the finned stator jacket to keep winding temperature within the Class F limit under rated load. Power conductors enter through a junction box on the left side, which suits layouts where incoming conduit or cable trays approach from that direction and keeps terminal access clear of the shaft workspace.

Position and speed data are returned through a digital multiturn absolute encoder, enabling closed-loop regulation without homing after power loss. The output shaft is balanced, uses a full-key configuration, and includes a shaft seal to help prevent lubricant egress while transmitting torque to keyed couplings. Because the motor is supplied without a holding brake, zero-speed load retention must be provided by external locking devices when required. Dynamic behavior is aided by vibration grade R, and the Side B face is machined without a shaft end to simplify overhung load calculations. The AS windings correspond to Rexroth drive software tables for current limits and thermal models during operation.
