Product Description:

The ADF104D-B05TA1-AS06-A2N2 belongs to the ADF Main Spindle Motors series from Bosch Rexroth Indramat. It is intended for high-speed machining centers that use asynchronous motor technology for continuous spindle duty. As a main spindle motor, it converts electrical energy into rotary motion for cutting tools while a liquid circuit removes heat during demanding production cycles. This type of motor is suited to applications where stable spindle speed and controlled operating temperature are important during long machining passes.

The motor uses digital servo feedback, allowing the drive to read encoder data for precise speed and position regulation. Mechanical integration is handled through flange mounting, which aligns the motor with the machine structure. Its cooling method is liquid cooling, so temperature is controlled by a coolant jacket rather than ambient airflow. The motor has size code 104 and length code D, giving it a stator stack suited to the torque demands of heavy milling. It also uses a standard bearing configuration and a plain shaft without keyways. Winding code AS is matched to this frame for the intended electrical characteristics, and this arrangement supports rigid installation in machine layouts that require consistent thermal control.

The rotor is supplied without a holding brake, so static holding force must come from the drive or external machine hardware. There is no shaft seal ring, which keeps the shaft interface simple where that feature is not required. Balance quality conforms to S DIN ISO 2373. The motor uses a connector/plug connection on the top surface, and cabling exits on side A to help keep nearby axes clear. A standard coolant inlet supports hose connection, the bearing arrangement supports axial loads typical of spindle service, and the lack of a second shaft end shortens the overall assembly. Power routing from the upper connection point can also help keep hose and cable runs away from the rotating shaft area.
