Product Description:

The ADF160B-B05TA3-CS07-A2N1 spindle motor is manufactured by Bosch Rexroth Indramat for integration into the ADF Main Spindle Motors series. It is a liquid-cooled asynchronous drive built for continuous duty in machining centers and similar automation where thermal stability and high spindle speeds are required. The construction follows the B length designation inside the 160 frame, so the active stack is extended without enlarging the flange footprint, allowing higher power density while keeping mounting interfaces unchanged.

The rotor is dynamically balanced to R DIN ISO 2373, a grade that limits residual vibration and protects precision bearings during high-speed service. Coolant enters through an axial rapid-action coupling, enabling quick line changes and minimizing downtime when the spindle cartridge is serviced. Position and speed are monitored through digital servo feedback with an integrated encoder, which feeds high-resolution signals to the CNC for closed-loop regulation. The stator stack belongs to size 160 hardware and uses flange mounting, so the machine frame absorbs radial and axial loads directly. Winding code CS sets the electrical impedance and thermal profile used by the matching drive.

This configuration is supplied without a holding brake, so any static clamping must be provided by external actuators rather than motor torque. Power enters the unit on side A through a sealed connector mounted on the top of the housing, which simplifies cable routing above the spindle nose. The motor uses a plain shaft to transmit torque without keyways, and it does not include a shaft seal ring because sealing is handled by the machine's pressurized coolant barrier. The opposite end of the rotor is closed because the motor is supplied without a second shaft end, which reduces overall length and removes an unused coupling point.
