Product Description:

The ADF164B-B35TC3-AS06-A2N1 is a liquid-cooled asynchronous main spindle motor built by Bosch Rexroth Indramat for the ADF Main Spindle Motors series. Designed for machine tools and production centers, the unit converts electrical energy into regulated spindle rotation for cutting, milling, and forming processes that require high duty cycles. Liquid cooling removes heat at the stator so rated torque can be sustained without external fans, making the motor suitable for enclosure installation where airflow is limited. This cooling method also supports continuous operation in applications where ambient cabinet air is not sufficient to remove heat from the spindle drive.

The motor size is 164, and it uses the compact B length, which provides a moderate axial dimension while preserving the active stack needed for spindle torque. Installation flexibility is provided by flange and foot mounting, allowing either rigid bed attachment or frame support. Heat is extracted through an axial coolant connection with a rapid-action coupling, so the machine side can be serviced quickly without draining the circuit. Position and speed data return to the inverter through digital servo feedback, and a plain shaft transmits torque directly to the toolholder without a shaft seal ring, which helps reduce radial drag during high-speed operation.

Dynamic balance is classified as R DIN ISO 2373, which helps limit residual vibration during prolonged spindle runs. Electrical power reaches the stator through a junction box mounted on top of the motor and oriented on side A, keeping cable routing clear of base mounts. It belongs to the Liquid-cooled asynchronous motors product family and is built without a holding brake, so the spindle can coast freely when power is removed. The motor also uses standard bearings and winding code AS, and it has no second shaft end.
