Product Description:

The ADF160C-B05TB1-BS06-D2N1 belongs to the ADF Main Spindle Motors series manufactured by Bosch Rexroth Indramat. This liquid-cooled asynchronous motor is intended for main spindle service in CNC machining centers, providing the rotational power required for cutting tools while remaining tightly regulated by the drive system. Within industrial automation cells, it functions as the prime mover for turning, milling, or grinding operations where constant speed accuracy is necessary.

The motor attaches to the machine frame through a flange mounting interface that ensures coaxial positioning with the spindle bearings. Rotor mass is balanced to quality grade R according to DIN ISO 2373, so vibration and noise stay within machine-tool limits. Torque is transmitted through a shaft with keyway that has been balanced with the complete key installed, eliminating supplementary trim. Standard roller bearings carry both radial and axial loads, and a shaft seal ring blocks coolant splash. Position and speed data are relayed via digital servo feedback, allowing the drive to correct errors during each control cycle. Continuous heat extraction is handled by the liquid-cooled stator jacket, keeping winding temperatures below allowable limits during long roughing passes.

Electrical supply conductors terminate on a plug-in connector positioned on the top of the housing, and the cable exit is directed toward Side B to simplify routing inside the machine enclosure. The unit is configured without a holding brake, so spindle clamping must be provided externally when the axis is idle. It occupies the 160 frame size with rotor length code C, giving a compact profile relative to its power output. A standard coolant connection is used across the series. The BS winding code identifies the coil set, and there is no second shaft end on Side B, which reduces overhang mass.
