Product Description:

The ADF134C-B05TA0-BS07-A2N1 is manufactured by Bosch Rexroth Indramat within the ADF Main Spindle Motors series. This liquid-cooled asynchronous spindle is intended for CNC machining centers, transfer lines, and other automated stations where high continuous power and tight speed control are required. Its flange housing lets the motor bolt directly to the machine frame, while internal coolant passages remove heat so the spindle can sustain demanding cutting cycles without derating.

The rotor is dynamically balanced to R DIN ISO 2373, limiting vibration that could otherwise mark workpieces or shorten bearing life. With a frame size of 134, the stator diameter provides ample magnetic surface for torque generation while still fitting common spindle envelopes. Installation uses flange mounting, so alignment with the machine headstock is set by the pilot diameter rather than an external foot. Liquid enters through an axial 1/4 in. thread port on the motor nose, which simplifies coolant manifold design. Position and speed data are supplied by digital servo feedback with an integrated encoder, allowing the drive to track spindle angle and synchronize tool changes. Standard rolling bearings carry the radial and axial loads generated during cutting.

Winding code BS gives resistance and inductance values matched to Indramat spindle drives. As a liquid-cooled asynchronous motor, it can operate at high power density without external fans, which helps reduce airborne debris in the machining zone. Power conductors exit on Side A through a top-mounted connector housing, so cable loops clear the machine bed. The rotor uses a plain shaft without a keyway, and torque is transferred by a shrink-fit toolholder to minimize imbalance. There is no holding brake, no shaft seal ring, and no second shaft end, which lowers inertia and avoids seal drag. Motor length code C identifies the axial size used when checking fit inside the spindle cartridge.
