Product Description:

The ADF132C-B05TA1-BS06-A2N2 belongs to the ADF Main Spindle Motors series manufactured by Bosch Rexroth Indramat. It is a liquid-cooled asynchronous spindle unit intended for machine-tool spindles and other rotating assemblies in automated production lines. Continuous coolant flow through internal channels removes heat from the stator so the motor can sustain high speeds with stable thermal behavior. This helps the drive maintain consistent speed and positioning accuracy during long machining cycles. Because heat is carried away by circulating liquid instead of relying only on ambient air, the motor also fits enclosed spindle housings where external ventilation is limited.

The frame size of 132 mm establishes the mounting footprint, while length code C indicates the active core depth and corresponding torque range. Position information is returned through digital servo feedback, giving the drive controller fine control over velocity and orientation during cutting cycles. Mechanical attachment is achieved through flange mounting, which aligns the housing to the spindle carrier without additional brackets. A plain shaft delivers torque directly to the toolholder, and its smooth surface is suited to clamping elements that do not use a keyed connection. The motor is supplied without a holding brake, so any required static locking must be provided by the machine design. The motor uses a standard coolant connection, and winding code BS indicates the electromagnetic characteristics matched to compatible drive inverters.

Dynamic behavior is improved by balance class S DIN ISO 2373, which limits residual vibration at operating speed. Power conductors terminate in a connector plug mounted on the top of the stator and routed to side A, which can simplify cable routing in vertical or horizontal spindle heads. This arrangement can also keep the cable outlet away from the shaft end on many spindle layouts. A standard bearing set supports the rotor. There is no shaft seal ring for pressurized fluid containment, and the design omits a secondary shaft end to reduce overall length. The compact single-ended layout is suited to spindle assemblies with limited installation space.
