Product Description:

The ADF132D-B05TR1-AS03-C2V1 is a main spindle motor manufactured by Bosch Rexroth Indramat for the ADF Main Spindle Motors series. It is a liquid-cooled asynchronous unit intended for high-speed machining centers and other industrial automation stations that require continuous torque delivery to the work spindle. By integrating the motor directly at the spindle, the design removes belt drives and delivers precise rotational power to cutting tools and workpieces. This direct arrangement also reduces mechanical compliance between the motor and spindle.

This motor is built as a liquid-cooled asynchronous machine, so internal heat is removed through a coolant jacket rather than ambient air to support long duty cycles. Mechanical attachment relies on flange mounting, which allows rigid alignment with the machine frame. A plain shaft is provided for direct coupling, and a shaft seal ring is installed to keep coolant and contaminants away from the bearing chamber. Rotor balance follows class R DIN ISO 2373, which limits residual vibration at rated speed. For axial and radial loads, the spindle uses heavy-duty bearings that withstand rapid tool changes and cutting forces. Standard coolant connection ports simplify hose routing, and the power leads terminate in a connector housing on top of the stator.

The frame size is 132, giving a stator diameter suited to medium-power machining centers, and the stator stack uses length code D for additional magnetic volume. Electrical characteristics follow winding code AS, matching ADF drives that supply the required current and frequency range. High-resolution motor feedback supports precise position estimation and stable spindle control during acceleration and speed changes. The power connection is oriented to the right. That arrangement leaves the rear side free for the spindle housing and adjacent machine components. There is no second shaft end on side B, and the motor does not include a holding brake, so an external clamping device or drive torque must secure the spindle when power is removed.
