Product Description:

The ADF132D-B05TR1-AS06-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 continuous duty on machine-tool spindles and other high-speed production axes where thermal stability and smooth rotation are critical to machining accuracy and surface finish. Its design is suited to applications that require steady speed control and consistent spindle behavior during long machining cycles.

The motor is built on size 132, so its stator diameter and mounting footprint match medium-frame spindles. The axial magnetic package with length code D uses a longer active iron stack for higher torque density. Winding code AS sets the voltage, current, and base-speed range for use with compatible inverters. Dynamic balance meets class R DIN ISO 2373, which helps limit vibration at elevated speeds. A set of heavy-duty bearings supports the radial and axial forces generated during aggressive cutting. Standard coolant ports simplify integration into closed-loop spindle chillers, the motor comes without a holding brake, a shaft seal ring helps keep cutting fluid out of the bearing cavity, and the design omits a second shaft end on side B to shorten overall length.

Mechanical attachment uses flange mounting, so the housing centers directly against the machine headstock for accurate alignment. Position and speed are reported through digital servo feedback, enabling the drive to correct load disturbances in real time. Three-phase power reaches the stator windings through a right-hand oriented conduit, with the connector housing on top of the frame and a connector plug interface for quick cable connection. The drive end uses a plain shaft that mates with commercially available tool retention systems, and the installed seal ring helps retain lubrication while reducing chip ingress.
