Product Description:

The ADF104C-B05TB1-AS06-A2N2 is a liquid-cooled asynchronous spindle motor manufactured by Bosch Rexroth Indramat for the ADF Main Spindle Motors series. As a main-drive element, it converts electrical energy into continuous rotary motion for metal-cutting and forming machines that demand stable torque at high duty cycles. Liquid cooling removes heat directly at the stator so the motor can maintain rated output in tightly enclosed machine frames without relying on ambient airflow. This layout supports steady spindle performance during long machining cycles and changing load conditions.

The rotor is balanced to S DIN ISO 2373, limiting residual vibration that could mark finished surfaces during precision machining. The motor uses flange mounting for rigid attachment to the machine bed. Size code 104 corresponds to the stator diameter, while length code C indicates an extended active core that increases continuous power density. Winding code AS corresponds to the conductor cross-section and turns count used for the torque and speed curve expected in high-speed spindles. A plain shaft without a seal ring helps minimize rotational runout, and the lack of a second shaft end reduces overhung mass on the non-drive side. Standard rolling bearings support axial and radial loads, and the standard coolant connection fits typical plant quick-couplers.

Position and speed are returned to the drive through digital servo feedback, enabling tight closed-loop regulation during tool changes and rapid feed moves. The power leads terminate in a connector plug mounted at the top of the housing and oriented toward side B, so cable trays can follow the machine column without sharp bends. A built-in liquid jacket circulates coolant through the housing, which eliminates external fan noise. The motor is supplied without a holding brake, so spindle clamping or orientation devices must be handled by separate mechanisms.
