Product Description:

The ADF104D-B05TB1-AS07-D2N1 is a main spindle drive produced by Bosch Rexroth Indramat for the ADF Main Spindle Motors series. Classified as a liquid-cooled asynchronous motor, it supplies continuous torque for demanding cutting and grinding spindles in automated machining centers. The frame uses size 104 and length code D, giving the rotor the mass and magnetic volume needed for mid-range power output while still fitting standard machine columns. Liquid circulation through the internal jacket removes heat from the stator and bearings, so the unit can remain thermally stable during high-duty operation without external fan noise.

Rotor balance accuracy meets R DIN ISO 2373, which helps limit residual vibration and protect tool life at elevated speed. Mechanical integration is handled through flange mounting, allowing the housing to bolt directly to the spindle headstock. The three-phase power exit is on side B, and the supply connector sits on the top of the terminal box; this orientation, together with the connector/plug interface, simplifies cable routing and disconnection when the motor is removed. A standard bearing set supports the shaft, and winding code AS matches the stator impedance to compatible Rexroth drives.

Speed and position feedback are handled through digital servo feedback with integrated encoder, eliminating the need for external tacho devices. For machines that use a separate braking system, the motor is supplied without a holding brake and without a second shaft end on side B, which shortens the overall length. The drive end uses a shaft with keyway, balanced with entire key, and a shaft seal ring helps block coolant or chip ingress into the front bearing. The coolant manifold uses the standard thread for this series, and the motor uses the standard ADF cooling connection type.
