Product Description:

The 2AD280B-B03LL1-AS06-E2N1 is produced by Bosch Rexroth Indramat as part of the 2AD 3-Phase Induction Motors series. It is an AC induction motor intended for variable-speed spindle and auxiliary drives in automated lines. The motor couples to driven equipment through a keyed shaft and relies on external drive electronics for closed-loop torque and speed control. In automated equipment, it provides rotary power for machine sections that need stable speed regulation during continuous production or changing process loads. Its large-frame design suits installations that require substantial output while still fitting common industrial machine layouts.

Mechanical configuration starts with standard bearings that carry radial loads and maintain axial alignment. Cooling air is pushed across the stator by an axial blower, allowing the frame to shed heat without liquid circuits. Power conductors terminate in a junction box on the left when facing the shaft, so power cables exit to that side. Installation on a baseplate uses foot mounting, so no flange adapter is required. The drive receives rotor position through digital servo feedback, enabling closed-loop control during speed and torque changes. The motor is supplied without a holding brake, so position holding during power-off must be provided externally. The shaft is balanced with a half key and is supplied without a shaft seal. The B-side is machined without a shaft end.

Frame size code 280 indicates a stator diameter suited for high power at moderate base speed. Length code B extends the core to increase continuous torque, and vibration grade R limits residual imbalance to meet ISO class requirements for large rotating assemblies. Electrical characteristics follow winding code AS, which sets phase resistance and leakage inductance for compatibility with standard 400 V inverters. These identifiers describe the motor’s size, active length, balance quality, and winding arrangement without changing its basic application as a three-phase induction motor.
