Product Description:

The ADF132C-B05TR1-ES03-B2N2 is a liquid-cooled asynchronous main spindle motor manufactured by Bosch Rexroth Indramat and supplied in the ADF Main Spindle Motors series. It serves as the core drive element for machine-tool spindles, converting three-phase electrical energy into precisely regulated rotary motion while moving heat through an internal coolant jacket. This cooling method helps the motor maintain stable operation during continuous-duty machining at high surface speeds. It is suited for applications that require controlled speed changes, repeatable torque delivery, and long operating cycles in enclosed machine spaces.

With motor size 132 and length code C, this spindle motor fits mid-range gantry mills and turning centers. Dynamic balance is trimmed to class S DIN ISO 2373, which helps reduce radial vibration during high-speed rotation. Mechanical retention uses flange mounting, and the standard angular-contact bearing set supports both cutting thrust and rapid acceleration. Mains power reaches the stator through a connector/plug oriented to the right, while the connector housing sits on top of the stator body so cables can clear the coolant manifold. Both the coolant and auxiliary service ports use a standard thread pattern for straightforward connection.

Closed-loop control uses high-resolution motor feedback to report rotor position to the drive. The rotor is supplied without a holding brake, which avoids added drag during high-speed machining. Torque is transmitted through a shaft with keyway that is balanced with the full key, while the B-side has no second shaft end to help limit rotating mass. There is no shaft seal ring because sealing is handled at the spindle nose. Electrical characteristics follow winding code ES, which is matched to the liquid-cooling circuit and rated inverter voltage.
