Product Description:

The ADF104C-B05TA1-CS06-D2N2 is a spindle motor produced by Bosch Rexroth Indramat and supplied within the ADF Main Spindle Motors series. The unit delivers rotary power to machining spindles while an internal cooling jacket removes heat generated during high-duty cycles. In automated production lines, the motor translates inverter current into precise speed and torque, allowing cutting, drilling, or grinding operations to maintain dimensional accuracy across long shifts.

Balance quality per S DIN ISO 2373 limits residual vibration so the rotor can spin at rated speed without damaging bearings or affecting surface finish. Position data is returned through digital servo feedback, enabling the drive to correct speed errors in real time. The motor uses a flange mounting interface that centers the 104-frame stator and removes the need for feet. Motor length C places the core between shorter B and longer D variants, matching thermal mass to the intended duty. For applications that stop and hold with drive torque alone, the motor is supplied without a holding brake, which reduces length and inertia. Thermal class and resistance values are linked to the CS winding code, giving the drive accurate current data for this version.

As a liquid-cooled asynchronous motor, the unit uses standard coolant fittings that connect directly to plant manifolds, and the standard bearing set supports axial loads generated during heavy cutting. The power plug is located on side A, and the connector housing sits on the top of the frame so cable bends can clear the machine bed. Power is supplied through a connector plug rather than terminal lugs, which helps keep installation straightforward. A shaft with keyway, balanced with the full key, transmits torque to the clamping system, while a shaft-side seal ring helps prevent coolant ingress. The motor omits a second shaft end to save space at the rear housing.
