Product Description:

Bosch Rexroth Indramat’s ADF134C-B05TA0-BS06-C2H1 belongs to the ADF Main Spindle Motors series and is classified as a liquid-cooled asynchronous spindle motor for machine-tool drives. In automated machining centers, it rotates the work spindle at controlled speeds while the external inverter closes the position loop through a digital feedback channel. Position and speed are reported by the integrated digital servo feedback module, eliminating the need for external encoders in the drive system.

The motor sits in the 134 frame class and is built in the medium C length, a geometry that balances torque output against space constraints on the headstock. Internal windings carry the dedicated BS code, indicating the impedance pattern expected by the Rexroth drive. Rotor symmetry is trimmed to a balance quality of R DIN ISO 2373, so vibration transmitted to cutting tools stays low even at elevated speed. A high-speed bearing set supports the shaft to tolerate the radial loads generated during heavy milling or drilling. There is no integrated holding brake, allowing faster runout and reducing mass on the rotor. Power enters through a plug connector mounted on the top of the housing, and the conduit points toward side A of the machine for shorter cable routing.

Liquid coolant reaches the stator jacket through an axial 1/4-inch coolant port; this connection thread is pre-machined for rigid piping so flow resistance stays minimal. The housing flange provides flange mounting holes for direct fit to the spindle cartridge, and a plain shaft exits on side A while side B remains closed because the design omits a second shaft end. A shaft-seal ring is installed to prevent coolant or lubricant from migrating into the bearing chamber, and the top connector orientation keeps wiring clear of chip flow paths.
