Product Description:

The ADF104C-B05TA1-BS06-C2N1 is a main spindle motor produced by Bosch Rexroth Indramat for the ADF Main Spindle Motors series. It is a liquid-cooled asynchronous motor used for machine-tool spindles and other continuous-duty axes that require stable torque during long operating periods. Its internal liquid circuit removes heat directly from the stator, which helps the motor maintain consistent output during sustained cutting, drilling, and milling work.

With a frame size of 104 and a motor length of C, the unit fits standard spindle housings used in compact and mid-size machining platforms. The rotor is balanced to R DIN ISO 2373, which helps reduce vibration and supports smooth spindle rotation during high-speed operation. The motor uses flange mounting, so the housing can be aligned concentrically to the machine headstock. Position and speed signals are provided through digital servo feedback, allowing the inverter to monitor the axis in closed-loop control. The motor is supplied without a holding brake, so the spindle must be secured by an external clamp or another holding method when power is removed. Standard bearings support the expected radial and axial loads, and an integral shaft seal ring helps block coolant from entering internal areas.

The electrical supply interface uses a connector plug oriented toward Side A. Its enclosure is located in a top housing position, which helps keep cable routing clear of nearby coolant hoses and adjacent machine components. A plain shaft on side A transfers torque directly to the spindle nose. The motor has no second shaft end on side B, which reduces overhang in compact spindle assemblies. The coolant connection follows the standard arrangement used across the series, and winding code BS identifies the electrical characteristics used by compatible ADF drives.
