Product Description:

The ADF132C-B05TA3-BS07-A2N1 is a liquid-cooled asynchronous main spindle motor supplied by Bosch Rexroth Indramat within the ADF Main Spindle Motors series. Designed for high-duty machining centers and other automated equipment, the unit converts electrical power into the controlled rotational motion required for cutting, drilling, or grinding heads. Liquid cooling helps the motor maintain stable torque during long production cycles, while integrated sensors send operating data to the drive controller so that spindle speed remains synchronized with process demands across long operating periods.

Its mechanical layout is governed by balance quality class R DIN ISO 2373, a vibration grade that minimizes runout at elevated speed. The motor attaches through a flange mounting interface that holds the 132 mm frame securely to the machine bed, and length code C indicates the axial envelope of the stator stack. Internal bearings use the standard configuration for this motor design. Winding code BS identifies the copper layout matched to the drive’s current range, and an axial rapid-action coupling coolant port allows hose changes without tools. Position and speed are relayed through digital servo feedback with an integrated encoder, enabling closed-loop control. For applications that stop solely through drive braking, the unit is supplied without a holding brake.

Electrical terminations are routed on side A of the housing, and the connector body is fixed at the top so cables clear adjacent modules. Power conductors use a plug-in connector for the main electrical connection. The rotor is fitted with a plain shaft, and there is no shaft seal ring, so external sealing is required if coolant mist is present. The motor is built without a second shaft end on side B, which reduces overhang length in tight spindle compartments and leaves more clearance around nearby machine parts.
