Product Description:

The ADF104B-B05TA1-BS06-C2N1 is a liquid-cooled asynchronous main spindle motor manufactured by Bosch Rexroth Indramat within the ADF Main Spindle Motors series. It is intended for integration into machining centers and other automated machine tools where continuous, thermally stable torque is required. The liquid circuit removes heat directly from the stator windings, allowing the spindle to sustain high speeds for extended duty cycles while supporting precise, sensor-guided positioning during milling, drilling, and turning operations.

Key construction parameters govern vibration control, mounting, and cabling. The rotor is balanced to R DIN ISO 2373, reducing residual motion that could affect surface finish. A flange mounting face lets the housing bolt directly to the machine frame, and supply conductors are brought in through a connector plug. Power is routed to side A, simplifying cable runs in vertical heads, while the housing carries the connection on the top surface for coolant clearance. Stator windings follow the BS code, aligning electrical resistance and thermal limits with the liquid-cooling capacity. Standard deep-groove bearings, a motor length code B, and a standard coolant port complete the mechanical envelope.

The motor uses frame size 104, which establishes the outer diameter compatible with ADF jackets. A plain shaft delivers torque without taper or external threads, and no shaft is present on the opposite end. The unit is supplied without a holding brake, so static load retention must be provided by external clamping devices. Motion control feedback is handled by digital servo feedback, which tracks rotor position for closed-loop drives. A shaft seal ring is fitted, coolant connections remain in the standard arrangement, and the top-mounted power box keeps electrical terminations clear of fluid lines.
