Product Description:

The ADF160B-B05TB1-BS03-A2N3 is a main spindle motor built by Bosch Rexroth Indramat for the ADF Main Spindle Motors series. It is a liquid-cooled asynchronous motor intended for milling and turning centers where long duty cycles and sustained spindle loads generate significant heat. When paired with a suitable drive, the motor provides stable rotary power for machine tools that need continuous torque during extended production operation. Its compact spindle format supports installation in equipment where reliable thermal control and steady shaft output are required.

This model is dynamically balanced to S1 DIN ISO 2373, which helps limit vibration at higher spindle speeds. The housing uses flange mounting, so it can bolt directly to the machine structure without extra brackets. Position data is returned through high-resolution motor feedback, allowing the control system to monitor spindle speed and phase during operation. The motor has motor size 160 and length code B, giving it a medium axial length within this frame. The winding code BS indicates the electrical winding arrangement used for this version, and standard rolling bearings support the rotor during normal spindle operation.

The electrical interface is arranged on side B, with the connection housing on top of the stator and a detachable connector that helps simplify cable routing inside vertical machine columns. Torque is transmitted through a plain shaft, and there is no shaft seal ring because the spindle is enclosed by the machine’s own sealing system. The motor is supplied without a holding brake, so a separate clamping device must hold the driven system when power is removed. There is no second shaft end on the rear face, and the coolant fittings follow the standard pattern used across the product line. The top-mounted connection point also helps keep the cable exit clear of the shaft line in enclosed spindle compartments.
