Product Description:

The ADF104D-B05TA1-AS07-A2N1 is a liquid-cooled asynchronous motor manufactured by Bosch Rexroth Indramat as part of the ADF Main Spindle Motors series. In industrial automation, it functions as a primary spindle drive, supplying controlled rotational power to machine tools or production centers that demand constant torque and precise speed regulation. By pairing with a compatible drive controller, the motor allows closed-loop control of spindle motion, minimizing thermal drift and supporting high material-removal rates over extended duty cycles.

Mechanical dimensions start with frame size 104, which sets the stator outer diameter and the interface dimensions for the surrounding spindle housing. Axial depth is identified by length code D; this longer core increases copper volume and therefore continuous power density compared with shorter variants. The unit is prepared for flange mounting, so its centering pilot and bolt circle mate directly with a machine headstock without additional brackets. Power conductors exit toward side A through a sealed connector or plug, and the connector shell is fixed on the top of the stator, simplifying cable runs in vertical installations. Position and speed are reported through digital servo feedback generated by an integrated encoder, allowing the drive to correct load disturbances in real time.

Dynamic smoothness is reinforced by balance grade R DIN ISO 2373, which limits residual vibration at high spindle speeds and protects the attached tooling. The rotor is supplied without a holding brake, so any static clamping must be provided by an external spindle lock. A plain shaft with no keyway supports precision collet or shrink-fit adapters, and winding code AS identifies the stator’s electrical constants so the matching inverter can be parameterized for accurate current, torque, and thermal monitoring.
