Product Description:

The ADF104B-B05TB1-BS06-A2N2 is a main spindle motor built by Bosch Rexroth Indramat and supplied within the ADF Main Spindle Motors series. As a dedicated spindle drive for machining centers and similar automation tasks, it converts drive power into continuous rotation while its liquid circuit removes excess heat so rated torque can be maintained during long production cycles. Standard bearings support radial and axial forces typical of spindle service.

The mechanical interface is prepared for flange mounting, enabling direct coupling to a machine frame without additional brackets. Power enters through cabling routed on side B, and the connector housing is located on the top of the stator so conduits can be dressed upward inside a cabinet. A sealed connector plug terminates the three-phase feed and keeps installation fast. The motor has size 104 and length code B, which correspond to the active iron stack and overall body length. A plain shaft carries the cutting load, and the shaft line remains single-ended because there is no second shaft on the rear.

This unit is a liquid-cooled asynchronous motor, and the coolant interface follows the standard pattern used across the family, allowing hose sets to attach without adapters. Dynamic balance reaches class S DIN ISO 2373, reducing vibration that could affect surface finish. Position data for the drive controller come from digital servo feedback, which transmits high-resolution rotor angle information over a serial channel. The motor is supplied without a holding brake, so braking must be handled by the inverter or an external clamp. It is also shipped without a shaft seal ring, a configuration used when the machine enclosure already prevents coolant ingress. A winding code BS identifies the stator coil set, and all hydraulic, electrical, and mechanical ports follow the standard build used across the family.
