Product Description:

The ADF132B-B05TA1-DS03-A2N1 is a main-spindle motor manufactured by Bosch Rexroth Indramat and supplied in the ADF Main Spindle Motors series. As a liquid-cooled asynchronous drive, it converts electrical power into continuous torque for turning, milling, or grinding spindles. It is intended for applications that require steady speed and high duty cycles in industrial automation.

The motor frame uses size 132, giving the stator and rotor a diameter suited for medium-power machine tools. Its mounting interface uses DIN-spec flange mounting, so the housing bolts directly to the machine headstock without intermediate brackets. Rotor balance is rated to class R DIN ISO 2373, which helps reduce vibration transfer to cutting tools. Integrated high-resolution motor feedback supports precise spindle speed regulation down to small incremental movements. The unit is supplied without a holding brake, so an external clamping device must secure the spindle when power is removed. A standard bearing set with plain-race ball bearings supports axial and radial loads, while the coolant ports use the series’ standard connection pattern for closed-loop liquid circulation. Power enters from Side A, and the connection housing sits on top of the stator to help keep cables clear of chip flow.

This product is a liquid-cooled asynchronous motor, which transfers thermal energy to coolant rather than the surrounding air and allows full-load operation inside sealed enclosures. Its shaft is a plain shaft with no keyway, which eases high-speed balancing and simplifies collet clamping. Electrical power is supplied through a keyed connector plug, and the winding identification code is DS, indicating the conductor cross-section and slot fill matched to DS-rated inverters. There is no shaft seal ring, so external sealing must be provided when coolant mist is present. Cables exit toward Side A through the top housing, and a second shaft end is not provided on Side B, maintaining a compact axial length coded as B.
