Product Description:

The ADF134C-B05TC3-BS00-C2N1 is a main spindle drive motor built by Bosch Rexroth Indramat for the ADF Main Spindle Motors series. It is an asynchronous induction motor intended to rotate machining centers, turning lathes, and other production spindles at controlled torque and speed. In automated lines, the motor couples directly to the spindle to provide continuous motion and quick reversals, while its liquid-cooling circuit removes heat during high-duty metal-cutting or forming processes. Its induction design suits machine tools that need stable spindle operation across changing load conditions.

This model is a liquid-cooled asynchronous motor, and coolant is connected through an axial rapid-action coupling to shorten hose attachment time during installation. The stator housing is prepared for flange mounting, so the frame bolts directly to a machine wall without intermediate brackets. The dynamic balance grade is R DIN ISO 2373, which helps minimize residual vibration that could affect surface finish. The motor has a plain shaft for rigid force transmission through shrink-fit or keyed toolholders. It uses motor size 134 and length code C, and it is equipped with standard bearings for general load profiles.

Three-phase power enters through a junction box on the housing face that points on side A. The box is mounted on the top of the stator, which helps keep clearance available for coolant hoses and chip guards around the machine. The motor is supplied without a holding brake, so any static clamping must be provided by an external spindle lock. An encoder port is not included, allowing the motor to be paired with separate feedback devices or with sensorless vector drives. The design also omits a second shaft end on side B and includes a shaft seal ring to help limit coolant ingress.
