Product Description:

The ADF132D-B05TR1-BD03-A3S1 is a main spindle motor produced by Bosch Rexroth Indramat in the ADF Main Spindle Motors series. Classified as a liquid-cooled asynchronous motor, it converts electrical energy into continuous rotary motion for cutting heads, boring spindles, and other high-speed tooling. By circulating coolant through its jacket, the motor maintains stable temperatures during sustained duty, permitting long machining cycles without thermal derating.

A balance quality rating of R DIN ISO 2373 keeps vibration within limits that protect tool faces and extend bearing life. The rotor is supported by a spindle bearing, a bearing class selected for high radial stiffness and low runout, so surface finish on the workpiece remains consistent. Installation is simplified through flange mounting, allowing the housing to bolt directly to the machine frame without additional brackets. Frame size 132 denotes the stator diameter group, giving a reference for envelope dimensions and compatible coupling hardware. Length code D identifies a medium-length stack that balances torque output with manageable mass for quick acceleration.

Closed-loop positioning is achieved via high-resolution motor feedback, enabling the drive controller to regulate spindle speed with fine incremental counts even at low revolutions. Power conductors terminate on a connector plug located at the top of the housing and oriented to the right, a layout that keeps cable bends shallow inside typical machine enclosures. The unit is delivered with a plain shaft, and a second shaft end on side B is provided for auxiliary encoders or manual handwheels. Because it is liquid cooled, only a standard coolant connection is required, and the design omits a shaft seal ring to avoid drag losses. The motor ships without a holding brake, so position holding must be provided by the drive during powered operation or by external equipment when the motor is stopped.
