Product Description:

The ADF104B-B05TA1-DS07-A2N1 is a liquid-cooled asynchronous main spindle motor produced by Bosch Rexroth Indramat for the ADF Main Spindle Motors series. Designed for machining centers and automated assembly equipment, the unit delivers continuous torque to machine spindles while its coolant jacket removes heat generated during extended high-speed operation. Integration with compatible Indramat drive controllers supports precise speed regulation along critical manufacturing axes and helps the spindle maintain stable operation when process loads change during cutting or other repetitive machine cycles.

As a liquid-cooled unit, the motor’s internal channels accept the standard coolant connection, so no custom manifolds are required. Its balance grade of R DIN ISO 2373 limits radial vibration that could affect surface finish. Position and velocity are returned to the drive through digital servo feedback with an integrated encoder, allowing tight electronic gearing and responsive control behavior. The frame corresponds to size 104 in the series and uses motor length B to keep the axial dimension compact. Mechanical attachment relies on flange mounting, and incoming three-phase power is routed through a sealed connector plug that keeps the electrical interface compact.

The stator winding follows the DS winding code, matching thermal and impedance characteristics to compatible ADF inverters. Power leads exit on side A, and the connector housing sits on top of the frame, which helps preserve clearance near adjacent guide rails in vertical spindle layouts. The rotor has a plain shaft with no keyway and is delivered without a holding brake, so standstill holding must be provided by the drive or an external mechanical device. A standard bearing set, the absence of a shaft seal ring, and the lack of a second shaft end keep the mechanical layout simple and help limit possible coolant entry points.
