Product Description:

The ADF100B-B05TA1-BS03-A2N2 is a liquid-cooled asynchronous motor manufactured by Bosch Rexroth Indramat for the ADF Main Spindle Motors series. Serving as a main spindle drive, it delivers continuous rotary power to machine tools and automated production lines where high speed and thermal stability are required. Integrated high-resolution motor feedback supplies the connected inverter with precise rotor position data, enabling accurate speed regulation and orientation during cutting, milling, or drilling operations. This arrangement supports stable spindle behavior during long duty cycles and repeated speed changes.

This model is built on frame size 100, and its active stack uses length code B. These dimensions give the motor a compact installation envelope while supporting the output expected from this spindle class. A rigid flange mounting interface aligns the stator bore concentrically with the machine bed, which helps reduce runout during operation. The stator jacket incorporates channels that support a liquid-cooled temperature control circuit, allowing high continuous current without excessive winding heat. Rotor balance conforms to S DIN ISO 2373, which helps limit vibration and supports operation at elevated speeds while maintaining smooth rotation.

For applications that rely on mechanical clamping or drive torque to hold position, the motor is supplied without a holding brake. The output shaft is a plain shaft, suited for coupling sleeves or hydraulic chucks rather than keyed transmissions. Power conductors terminate in a sealed connector plug situated at the top of the side A housing, which keeps cabling clear of coolant manifolds and bearing service zones. The motor also uses standard bearings and a standard coolant connection. It has no second shaft end and no shaft seal ring, which keeps the layout straightforward for spindle installations that use external retention and sealing methods.
