Product Description:

The ADF160C-B05TA3-BS03-B2N1 is a liquid-cooled asynchronous main spindle motor produced by Bosch Rexroth Indramat for the ADF Main Spindle Motors series. As a spindle drive, it converts electrical energy into continuous rotary motion that supports machining centers, lathes, and other automated equipment that demand high torque at stable speed. The stator jacket is built for immersion cooling, so conditioned fluid can circulate through the motor body to keep winding temperatures steady during extended duty cycles. This cooling method helps the motor maintain consistent operation in applications that run for long periods under heavy load.

With a frame that corresponds to 160, the motor occupies the mid-range size in the series and delivers mechanical rigidity suitable for metal-cutting spindles. Length code C extends the active stator core so higher rated power can be extracted while keeping the envelope compact. Rotor balance complies with R DIN ISO 2373, which reduces residual vibration at the spindle. Installation relies on flange mounting, so alignment takes place on a single pilot diameter without auxiliary feet. Position feedback is handled by the integrated high-resolution motor feedback system, allowing the drive to regulate speed and position within tight tolerances. Heat removal and coolant supply enter through an axial port with a rapid-action coupling, which allows quick hose changes.

The unit is delivered without a holding brake, making it suitable for spindle applications where free coast-down after power is removed is acceptable or an external clamp is used. Power cables are oriented toward side A, and the connector housing is on top of the stator, which simplifies routing in vertical machine frames. The top-mounted connector layout also helps keep cable paths clear of nearby machine structures. Torque is transmitted through a keyway shaft balanced with the full key, so coupling elements can be mounted directly without additional balancing work.
