Product Description:

The ADF104C-B05TA1-BS07-C2N2 is a liquid-cooled asynchronous main-spindle motor manufactured by Bosch Rexroth Indramat for the ADF Main Spindle Motors series. Designed for machine-tool and production-cell spindles, the motor converts inverter output into continuous rotary motion while an internal coolant jacket removes heat generated during high-speed cutting. The combination of encoder feedback and liquid cooling helps it maintain stable speed and torque under changing load conditions typical of industrial automation. Because heat is carried away by coolant rather than external airflow, the motor can support sustained spindle duty in enclosed machine spaces.

This model is balanced to Class S under DIN ISO 2373, which helps limit residual vibration that can affect tooling and surface finish. Mechanical attachment relies on flange mounting, and the C-length frame keeps the overall package short. Motion feedback is provided by digital servo feedback with an integrated encoder, allowing the drive to monitor position directly during spindle operation. Power enters through a connector plug, and the connector housing is located on the top of the stator while the cable exits toward Side A for straightforward routing. A shaft seal ring helps protect internal parts from coolant splash, and the motor uses standard bearings with the standard hose set for the coolant connection.

The motor is supplied without a holding brake, so the spindle must be clamped externally when it is at rest. Its plain shaft supports coupling with hydraulic or mechanical tool-clamping systems, and frame size 104 provides the mounting diameter used for matching spindles in this size class. Within the liquid-cooled asynchronous motors product group, winding code BS gives copper fill and thermal behavior suited to continuous inverter duty. There is no second shaft end on Side B, which reduces mass and leaves the opposite end free of additional rotating output hardware.
