Product Description:

The 2AD280B-B03LL1-AS07-B2V1 is an AC induction motor produced by Bosch Rexroth Indramat for the 2AD 3-Phase Induction Motors series. It serves as a main drive for conveyors, extruders, and other automated equipment by converting three-phase electrical power into controlled mechanical rotation. This motor type is well suited to applications that need stable speed under changing load and continuous industrial duty. A modular frame and standardized connections support integration into automated equipment with consistent mechanical and electrical interfaces.

The frame indicator 280 points to a large stator diameter for high continuous torque, while length code B indicates a medium active core that helps keep rotor inertia from becoming excessive. Cooling is supplied by an Axial Blower that forces air along the housing to keep the windings within their temperature range. Rotor support relies on heavy-duty bearings, which are intended to absorb substantial radial and axial forces from belt-driven or heavily loaded arrangements. The motor uses foot mounting, so the housing can be bolted directly to a machine base for rigid installation. Because the motor is supplied without a holding brake, any application that must lock the shaft during a power-off condition needs external braking or drive-applied holding torque.

The winding designation AS matches the motor's electrical characteristics to compatible Rexroth inverters for controlled current delivery. Position data come from digital feedback with a multi-turn absolute encoder, allowing accurate closed-loop speed regulation and retention of turn count after shutdown. Power and signal conductors terminate inside a left-oriented junction box, matching the left-side connection direction and helping keep cable routing orderly. The shaft is balanced with its full key, is configured without a shaft seal, and the rear face has no shaft end, which reduces drag and suits applications that do not require rear mechanical takeoff. Vibration grade R helps limit oscillation levels that can affect couplings, bearings, and connected drivetrain components during operation.
