Product Description:

The ADF164B-B05TD0-AS06-A2N1 is a main spindle motor supplied by Bosch Rexroth Indramat within the ADF Main Spindle Motors series. It drives the primary spindle of machining centers, lathes, and grinding machines. It delivers controlled rotary motion under CNC or PLC command so cutting speed and surface quality remain consistent across varying loads.

The motor size and mounting features set its integration envelope. The size code 164 refers to the stator outside diameter, and the B length option provides a medium axial dimension for mid-range power ratings. A flange mounting interface positions the unit directly against the machine frame, supporting radial and axial forces without intermediary brackets. Rotor balance is certified to R DIN ISO 2373, a grade that keeps residual vibration low for high-speed finishing. Position and velocity operate in closed loop through digital servo feedback, enabling immediate correction of load disturbances. Power conductors exit the stator on side B, which simplifies cable routing inside vertical or longitudinal beds. Standard bearings carry radial loads, the motor is supplied without a holding brake, and the power housing sits on top of the stator to preserve clearance around the spindle nose.

The connection chamber is a sealed junction box that provides strain relief and separate terminals for the three-phase supply and temperature sensors. A plain shaft with a ground cylindrical surface accepts shrink-fit or keyed tool adapters while minimizing added inertia. Because the unit belongs to the liquid-cooled asynchronous motors product group, coolant passages in the stator jacket extract heat so continuous duty is possible inside enclosed spindle cartridges. Winding designator AS is used for the copper fill, insulation system, and electrical constants selected for medium-voltage inverters, allowing quick parameter entry. A shaft seal ring is omitted to reduce friction losses when the motor is installed within a sealed machine enclosure.
