Product Description:

The ADF134D-B05TA3-BS07-A2N1 belongs to the ADF Main Spindle Motors series manufactured by Bosch Rexroth Indramat. It is a spindle motor intended for machine tools and other automated stations where continuous, controllable torque is required at high rotational speeds. Because the motor is integrated into the machine structure rather than used as a separate gearbox-driven unit, it helps simplify wiring, cooling, and feedback connections in industrial automation.

The rotor is dynamically balanced to the R DIN ISO 2373 quality grade, which helps limit vibration during rapid acceleration. Cooling fluid reaches the stator through an axial rapid action coupling, and this quick-disconnect connection keeps the liquid channels sealed during removal. Position and speed are monitored by a digital servo feedback system with an integrated encoder, allowing closed-loop control from the connected drive. The motor is supplied without a holding brake, so external clamping is required when the shaft must remain locked at standstill. A rigid flange mounting face mates directly to the machine frame, and the housing corresponds to motor size 134 within the series. The D length code indicates the overall motor length in the product family, while winding code BS corresponds to the resistance and inductance values expected by the inverter.

Power enters the unit through a connector oriented on Side A, and the connector's top housing position helps keep cables clear of coolant manifolds. The assembly is a liquid-cooled asynchronous motor, so forced coolant circulation removes heat without relying on ambient airflow. Standard bearings support the plain shaft, and there is no shaft seal ring because the machine enclosure provides the required barrier. Only one shaft end is provided, with the Side B end closed, which helps reduce the axial space needed inside compact spindle cavities.
