Product Description:

The ADF132D-B05TR1-AS03-A2N1 is a main spindle unit produced by Bosch Rexroth Indramat for the ADF Main Spindle Motors series. It is a liquid-cooled asynchronous motor intended to rotate machine-tool spindles and other continuous-duty axes in automated lines. In service, it supports cutting, drilling, milling, and similar processes that require consistent spindle rotation. The asynchronous design suits long operating cycles where dependable thermal behavior and compact mounting are important.

This model is manufactured to the vibration grade R DIN ISO 2373, limiting residual imbalance so surface finish quality is not compromised at high speed. Position data are returned through high-resolution motor feedback, enabling the drive to close tight velocity loops during tool changes and threading cycles. Mechanical attachment is achieved with flange mounting, which keeps axial alignment within the machine frame without foot plates. Electrical power reaches the stator through a connector plug in a housing on top of the motor, while the cable exits to the right for cleaner routing inside vertical cabinets. A plain shaft transmits torque directly to the spindle cartridge. The unit also uses standard rolling bearings, liquid cooling through a standard hose interface, and standard balance quality to support continuous thermal loading.

The frame is cataloged as motor size 132 with motor length D, providing the magnetic volume needed for high continuous power in a relatively short body. Winding configuration AS indicates the stator conductor cross-section and impedance used by the matching drive amplifier. The motor is supplied without a holding brake, so deceleration must be controlled by the drive rather than by a mechanical brake. There is no shaft seal ring, and there is no second shaft end on side B, which helps reduce rotating mass and simplifies lubrication. A right-side power entry and a top-mounted connector housing support straightforward integration in CNC machine layouts.
