Product Description:

The 2AD100B-B05OB2-AS03-B2N1 is manufactured by Bosch Rexroth Indramat within the 2AD 3-Phase Induction Motors series. Designed for integration into CNC machines and other automated equipment, this motor converts electrical power into continuous rotary motion for spindles, transport rollers, and auxiliary axes. Its frame size of 100 supplies the torque margin needed for medium-duty tasks, while the compact motor length code B keeps the overall package length manageable when the unit is installed inside enclosed machinery.

A built-in axial blower provides forced-air cooling; the impeller is energized from 230 V and moves air across the stator housing to stabilize winding temperature. This cooling method is described as axial blower cooling, allowing the motor to sustain rated current without relying on external airflow. Mechanical attachment uses flange mounting, so the housing seats directly against a machine wall without foot brackets. The power connector exits on Side B, and the plug uses a Top entry orientation to simplify cable routing in vertical cabinets. A screened connector terminates the stator leads for EMC compliance, standard bearings support the rotor, and the absence of a shaft end on side B reduces overhung mass.

Control feedback is delivered by high-resolution motor feedback, enabling tight speed loops when paired with Indramat digital drives. The motor is supplied without a holding brake, which removes residual drag during high-speed operation and leaves position locking to external mechanics when power is absent. Dynamic balance is rated to vibration grade R, helping reduce structure-borne noise in precision machines. The stator uses winding code AS, so its electrical characteristics match compatible drive modules in the Indramat portfolio. The shaft has no seal but is balanced with the entire key, allowing coupling to standard clamping hubs, and the open design on side B omits a shaft end to leave space for the internal cooling hardware.
