Product Description:

The ADF134D-B35TA0-BS06-A2N1 is a main spindle motor produced by Bosch Rexroth Indramat and supplied within the ADF Main Spindle Motors series. The unit is intended for machine tools and other automated systems where high-speed rotation and regulated torque are required on the primary spindle. By integrating a liquid cooling circuit and digital position feedback for the drive controller, the motor supports continuous duty cycles and precise speed regulation in demanding production cells.

Dynamic behavior starts with its balance classification of R DIN ISO 2373, a grade that limits residual vibration so the spindle can operate at speed without chatter. Frame designation 134 sets the stator diameter and the overall mechanical envelope. An axial 1/4-inch threaded coolant port routes liquid through the housing to remove heat from the rotor and stator. Position data is returned via digital servo feedback, allowing tight speed loops. Power reaches the windings through a connector on the top of the terminal box, and the connection is oriented toward Side A for straightforward cable routing. A standard rolling bearing set supports the rotor, while the BS winding code aligns impedance with Indramat inverters.

The motor supports flange and foot mounting, giving a choice between face or base attachment. It uses a plain shaft that mates directly with tool-holding assemblies and is supplied without a holding brake to avoid drag during continuous rotation. As a liquid-cooled asynchronous motor, it is suited for extended cutting cycles where stable temperature control is important. Length class D increases stack height for higher power, and the design omits a shaft seal ring because the machine enclosure protects the coupling. Only one shaft emerges, because the Side B end is closed and there is no second shaft extension.
