Product Description:

The ADF134D-B05TC0-BS07-A2N1/S032 is a liquid-cooled asynchronous main spindle motor built by Bosch Rexroth Indramat for the ADF Main Spindle Motors series. Supplied as a self-contained rotating unit, it acts as the primary drive for milling heads, turning centers, and other automated machine tools where stable speed regulation and high continuous duty are required. The motor interfaces with Indramat drive electronics to provide closed-loop spindle positioning and feed force generation in industrial automation cells.

Its balance quality is rated at R DIN ISO 2373, which helps minimize radial vibration that could affect surface finish. An axial coolant connection with a 1/4-inch thread routes liquid directly through the stator jacket for high thermal throughput. The digital servo feedback with an integrated encoder supplies rotor position data to the drive, supporting fine speed control during threading or contour cutting. Installation uses flange mounting, and the terminal conduit faces side A so cables can align with the machine column. Mains power enters through a sealed junction box, which helps keep conductors isolated from coolant splash. The unit is delivered without a holding brake, without a shaft seal ring, and with standard bearings so the surrounding machine design can provide the required clamping or sealing arrangement.

The motor size 134 stator and motor length D stack provide an extended magnetic path that works with the BS winding code to support the continuous torque expected from this frame class. A plain shaft on the drive end allows direct coupling with toolholders by shrink fit, while the omission of a second shaft end on side B helps keep the overall length shorter. Because the power connection housing sits on the top of the frame, cable bends can clear nearby machine structures more easily. The coolant-ready housing also supports stable thermal operation so the standard rolling-element bearings can remain within their expected service life during continuous fluid circulation.
