Product Description:

The ADF132D-B05TB1-AS03-A2S1 spindle motor is produced by Bosch Rexroth Indramat for the ADF Main Spindle Motors series. As a liquid-cooled asynchronous main drive, it converts electrical energy into high-speed rotation for milling, turning, and grinding centers where stable torque over long duty cycles is required. This motor is intended for machine-tool spindles that need repeatable speed control during both roughing and finishing passes. It is used with compatible drive controllers so machining axes can maintain constant surface speed with limited thermal drift.

In operation, the liquid-cooled asynchronous motor channels coolant through the stator jacket, preventing overheating during continuous duty cycles. The integrated high-resolution motor feedback system supplies precise rotor position data to the drive, enabling fine surface finishes. A flange mounting interface seats the housing directly against the machine bed, which helps reduce stack-up tolerance. The rotor is balanced to R DIN ISO 2373, limiting residual vibration that could mark the workpiece. Frame designation 132 indicates the outer diameter and gives the motor the footprint expected for mid-power spindle stations. A spindle bearing set carries axial and radial loads from cutting forces, and the standard coolant connection simplifies plumbing with existing hose hardware.

Length code D indicates the active core depth, which helps establish the torque-to-speed curve during sizing. Power is delivered through a top-mounted connector plug facing side B, keeping cable runs clear of the coolant unions. The shaft is a plain shaft, and no shaft seal ring is fitted because the motor is typically coupled to a sealing cartridge in the spindle head. Winding designation AS identifies the electrical characteristics presented to the drive, and the unit is supplied without a holding brake or a second shaft end on side B.
