Product Description:

The ADF134B-B05TA0-BS06-A2N2 is a main spindle motor produced by Bosch Rexroth Indramat and organized under the ADF Main Spindle Motors series. As a liquid-cooled asynchronous unit, it supplies continuous torque to machine-tool spindles and other production axes in demanding industrial service. Its cooling arrangement supports high duty cycles and helps the motor operate for extended periods without overheating.

Rotation precision is supported by a balance quality grade of S DIN ISO 2373, which limits residual vibration and helps protect high-speed bearings. Cooling fluid enters through an axial 1/4-inch connection thread, so the plumbing can stay aligned with the shaft and connect through standard hydraulic fittings. Position data reaches the drive through digital servo feedback, enabling closed-loop speed control during tapping, milling, or boring. The motor is built without a holding brake, so stopping torque must come from the inverter or an external clamp. Mechanical attachment uses flange mounting, which helps reduce axial misalignment during installation. The motor uses a standard bearing arrangement, and the plain shaft simplifies coupling, but the lack of a shaft seal ring means the installation area should remain clean.

The remaining configuration values cover connectivity and dimensional fit. Frame size 134 sets the housing diameter, while length code B indicates the stack height for the required power range. Power is fed through a connector that points to Side A, and the connector housing is mounted on the top of the stator so cable bends can clear adjacent equipment. The winding identification BS matches the current limits and thermal model used by the compatible drive, and there is no second shaft end on side B, which leaves the rear of the motor clear for encoder-related components.
