Product Description:

The ADF132C-B05TB1-BS03-A2N3 is a main spindle motor produced by Bosch Rexroth Indramat for the ADF Main Spindle Motors series. As a liquid-cooled asynchronous motor, it serves as the primary drive on machining centers and other automated equipment where continuous torque and stable speed are required. Its mechanical layout supports direct integration with machine structures and allows the motor to operate with a matched inverter in closed-loop spindle applications. This arrangement is commonly used where spindle speed must remain consistent across long duty cycles and varying cutting loads.

The ADF design uses a liquid-cooled asynchronous motor construction that channels coolant through the stator jacket to remove heat without external fans. Its frame size is 132, and the unit uses flange mounting, so it can seat directly against the spindle housing without extra brackets. Position data are returned through high-resolution motor feedback, which supports precise speed regulation and stable spindle response under changing loads. The three-phase power lead terminates on a connector plug located at the top of the housing and routed on side B, which helps keep cable routing orderly inside enclosed machine spaces. By removing heat through the housing, the motor suits installations where fan-driven airflow is less desirable around chips, dust, or coolant mist.

Dynamic smoothness is indicated by balance class S1 DIN ISO 2373, which helps reduce vibration at high spindle speeds. The electromagnetic package uses winding code BS, matched to the electrical characteristics required for this motor length. Because the motor is supplied without a holding brake, the shaft remains free of brake drag during rapid acceleration and deceleration. A standard bearing arrangement supports the shaft, and the motor is built without a shaft seal ring or second shaft end. The absence of those external shaft features can simplify coupling arrangements on machines that use a single driven end.
